What does Romans 12:2 mean?

The Greek noun is age, not world; interpreters dispute whether the two verbs differ, how to render 'reasonable service', and what renewal means for reason.9 sources9 sources1.

Established: the noun usually translated world is aion, 'age'; the verb for 'be conformed' appears elsewhere in the New Testament only in 1 Peter 1:14, and the verb for 'be transformed' otherwise only in 2 Corinthians 3:18 and the transfiguration accounts; English editions split three ways on logike latreia in 12:1. Interpretation: Sanday and Headlam, after Lightfoot, read the verbs as outward fashion against inner nature, while Peterson (1993) reports that they are now widely held to be near-synonyms; Bruce, as Summers quotes him, reads 'spiritual worship' as probably set against the temple cult, while Schreiner argues for 'rational'.

The Greek wording and its English renderings are documented; whether the two verbs differ, how to render logike latreia, and what renewal means for reason and culture are disputed among interpreters; divine renewal is a theological claim.

What people get wrong

Text

Things people commonly believe the text says, checked against it.

  • A common belief among believers

    Myth World in this verse translates kosmos and means the physical world.

    Actually The Greek noun is aion, glossed age. Sanday and Headlam explain its moral force through the contrast between the present age and the age of the Messiah, and Calvin takes it as the sentiments and morals of men.5 sources5 sources2. this site's data3. Romans 12:224. Sanday 190225. Sanday 190226. Calvin 1849

  • A common belief among believers

    Myth Romans 12:2 says not to let the world squeeze you into its mould.

    Actually That wording comes from J. B. Phillips' paraphrase in The New Testament in Modern English, which also has God re-moulding minds from within. The Greek verbs are syschematizo, 'be conformed', and metamorphoo, 'be transformed'.4 sources4 sources27. Phillips 1960, 197228. this site's data29. 1 Peter 1:1430. this site's data

  • A common belief among believers

    Myth To 'prove' God's will means to demonstrate it to others.

    Actually In older English prove meant test. Owen gives the verb's chief senses as to test, to approve what is tested and to discern, and the BSB has test and approve.31 32

  • A common belief among believers

    Myth Every Greek edition prints the two verbs as commands.

    Actually The Robinson-Pierpont Byzantine text prints infinitives, continuing the appeal of 12:1, while the SBL Greek New Testament, Textus Receptus and Scrivener print commands. The meaning hardly changes.33

  • A common belief among skeptics

    Myth Anabaptist readers simply equate plain clothing with a transformed mind.

    Actually Conservative Anabaptist Asher Witmer argues that refusing certain clothes transforms no one and criticizes plain circles that mistake plainness for renewal. Roth acknowledges that nonconformity has sometimes become legalistic and oppressive.20 34

  • A common belief among skeptics

    Myth Christian interpreters use this verse to tell believers to stop thinking.

Hard questions

The strongest case, the strongest responses, then a plain assessment of where the logic holds.

Do 'conformed' and 'transformed' contrast outward fashion with inner nature?

The two verbs are documented; whether their roots contrast outward fashion with inner nature is disputed, with Peterson reporting in 1993 that they are widely held to be near-synonyms.

See the argument

The strongest case

Sanday and Headlam, following Lightfoot's distinction between schema and morphe, paraphrase the verse as forbidding the adoption of the external and fleeting fashion of this world and calling for transformation in one's inmost nature. Chrysostom had argued that Paul wrote 'be transformed' rather than 'change the fashion' to show that the world's ways are a fashion, while virtue is a real form with a natural beauty of its own.9 sources9 sources28. this site's data29. 1 Peter 1:1430. this site's data5.

  1. P1. The verb for 'be conformed' (syschematizo) contains schema, 'fashion, outward form'; the verb for 'be transformed' (metamorphoo) is the one used of Jesus' transfiguration.4 sources4 sources28. this site's data29. 1 Peter 1:1430. this site's data5. Sanday 1902No listed response challenges this premise
  2. P2. The two roots keep their difference here, so Paul is contrasting a surface fashion with a change of inner form.

→ Conclusion. Romans 12:2 forbids taking on the world's passing outward fashion and calls for a change in one's inmost nature.

Strongest responses

Protestant: evangelical challenges P2

The verbs are near-synonyms, with a difference of emphasis. Peterson (1993) reports that the two verbs are now widely held to be more or less synonymous in Koine Greek, his own characterization of the field rather than a cited survey. He still finds a difference of emphasis. The passive 'be transformed' suggests God's work through his Spirit, and the present imperatives point to ongoing human responsibility.6

Protestant: evangelical challenges the framing

Inward first, outward included. Piper notes that the verb for 'transformed' is used in the Gospels of Jesus' transfiguration, and argues that nonconformity to the world does not primarily mean the external avoidance of worldly behaviours, while adding that such avoidance is included.21

Protestant: Methodist challenges the conclusion

Judgment, spirit and behaviour. Wesley glosses 'that ye may prove' as 'know by sure trial', and says that not being conformed to the world applies 'neither in judgment, spirit, nor behaviour'.39

Protestant: Reformed challenges the framing

The world as an outlook and morals. Calvin says the term world has several meanings, but here it means the sentiments and the morals of men.26

Plain assessment

The word data are not disputed. Schema sits inside the first verb, and the second is the transfiguration verb. Sanday and Headlam, after Lightfoot, and Chrysostom build an outward-versus-inward contrast on that. Peterson (1993) reports that they are now widely held to be near-synonyms in Koine Greek, yet keeps a difference of emphasis between God's work and human responsibility. Piper reaches an inward-first reading through the transfiguration link, and Wesley names behaviour alongside judgment and spirit.

What would change this assessment: A current lexical study of syschematizo and metamorphoo in Koine texts, read directly rather than through Peterson's summary.

Is logike latreia 'spiritual worship' or 'reasonable service'?

No cited interpreter settles it; Bruce leans to spiritual with a 'probably', Schreiner argues for rational, Peterson for understanding worship, and editions split among reasonable, spiritual and intelligent.

See the argument

The strongest case

F. F. Bruce, as Summers quotes him, allows that logikos may mean 'reasonable' or 'spiritual', but judges that 'spiritual worship' is probably set in contrast with the externalities of Israel's temple cult. Chrysostom, as Owen reports, took the word as spiritual, belonging to the mind; the ASV, WEB, BSB, ESV and RSV all render it spiritual.9 sources9 sources40. this site's data4.

  2. P2. Paul's contrast is with the externals of temple sacrifice, so the adjective names inward, spiritual worship rather than material offering.

→ Conclusion. Spiritual worship is the better rendering.

Strongest responses

Protestant: evangelical challenges the conclusion

Rational and reasonable. Schreiner, as Summers reports, bases his reading on parallel uses in Greek philosophy and concludes that Paul intends the sacrifice to be 'rational and reasonable', denying that spiritual alone does justice to the phrase.16

Early church: Greek challenges P2

Against the law's sacrifices, yet reasonable. Owen reports that OrigenOrigenA Christian scholar and teacher of Alexandria, born in 185 and deceased probably in 253 or 254, according to the Catholic Encyclopedia. Marco Rizzi explains that he interpreted the Septuagint allegorically, like Philo.From: Prat; Prat; Prat; Rizzi; PratAll terms →, and many after him, took the word as designating Christian service consonant with reason, in opposition to the sacrifices under the law.41

Protestant: evangelical challenges the framing

Understanding worship. Peterson thinks spiritual worship risks over-stressing inwardness, while rational worship may suggest only a contrast with irrational animals. It may be best, he says, to read understanding worship, consonant with the truth of the gospel and offered by those who understand it.17

Protestant: Reformed challenges the framing

Reasonable means bounded by God's word. Calvin reads reasonable service as excluding every self-devised form of worship. Paul, he says, repudiates as foolish whatever is attempted beyond the rule of God's word.42

Catholic challenges the framing

Reasonable means measured. Aquinas reads the VulgateVulgateA Latin Bible closely associated with Jerome, with contributions from other translators. Dionisio Candido writes that it was the official Bible of Western Christianity for centuries.From: CandidoAll terms →'s rationabile obsequium as presenting one's body to God with discretion, whether by martyrdom, abstinence or any work of justice. He goes on to quote JeromeJeromeA Latin Church Father associated with the Vulgate, born in the fourth century and deceased in 420. Birth dates differ: Louis Saltet gives about 340–342, while Dionisio Candido gives 347.From: Saltet; CandidoAll terms → against fasts and vigils so extreme that they damage a sound mind.9

Plain assessment

Bruce reads spiritual worship as probably set against the temple cult, a hedged judgment; Owen reports that Origen drew that contrast but read the word as reasonable. Schreiner argues for rational from Greek philosophy, and Peterson proposes understanding worship. Calvin and Aquinas give reasonable their own sense, bounded by God's word or measured with discretion. Summers calls the phrase elusive and enigmatic, and the cited editions split three ways.

What would change this assessment: A direct study of logikos in first-century Greek worship language, beyond its single other New Testament use in 1 Peter 2:2.

What is the 'will of God' you can test and approve, and how is it known?

The verb means testing that leads to approval or discernment; whether God's will is known chiefly by experience, commandments, renewed judgment or prayer differs by tradition.

See the argument

The strongest case

Luther, preaching on Romans 12, says God's will is ever good, but human reason imagines it to be the evil, unfriendly, abominable will of the devil. Therefore, he says, Christian experience must come to the rescue and decide; it must feel and prove, test and ascertain that will.9 sources9 sources31. this site's data4.

  1. P1. The verb, dokimazein, is rendered prove (KJV, ASV, WEB), test and approve (BSB), and in the ESV 'by testing you may discern'.31 4No listed response challenges this premise
  2. P2. Because reason misjudges God's good will, the testing is done by experience rather than by reasoning.

→ Conclusion. To prove God's will is to come to know its goodness by Christian experience, against reason's verdict.

Strongest responses

Tradition unspecified challenges P2

Test, approve, discern. Owen, Calvin's 1849 translator, gives the verb's chief senses as to test, to approve what is tested and to discern, and judges discern the most suitable sense here. He records Jerome's 'carefully search' and Theophylact's 'know'.32

Academic (critical) challenges P2

The intellect made exact. Sanday and Headlam say the result of renewal is to make the intellect, the seat of moral judgement, true and exact in judging spiritual and moral questions.25

Protestant: Methodist challenges the conclusion

Sure trial of God's commands. Wesley glosses 'that ye may prove' as 'know by sure trial', and takes the will of God to be all the preceptive, or commanding, part of Christianity.39

Protestant: Reformed challenges the conclusion

God's commandments as the measure. Calvin says that, against the world's confidence in its own inventions, Paul teaches that what is good and right must be ascertained from God's commandments.44

Catholic challenges the framing

Discernment through prayer. The Catechism, citing Romans 12:2 in its teaching on the Lord's Prayer, says that by prayer we can discern what is the will of God and obtain the endurance to do it.45 46

Plain assessment

The editions agree that the verb involves testing; Owen adds approving and discerning and prefers discern here. Luther hands the decision to Christian experience because reason misjudges God's good will. Wesley speaks of sure trial and of God's commands, Calvin of God's commandments as the standard, Sanday and Headlam of a renewed intellect judging exactly, and the CatechismCatechism of the Catholic ChurchAn official summary of Catholic teaching that John Paul II ordered published in 1992, declaring it a sure norm for teaching the faith. He approved and promulgated its Latin typical edition in 1997.From: II; II; II; II; IIAll terms → of prayer.

Does nonconformity call for a visibly separate life, or for changing the culture?

The verse is read both ways; Anabaptist writers ground visible nonconformity in it and Yu applies it to transforming culture, while Witmer and Roth caution against equating plainness with renewal.

See the argument

The strongest case

Amish writer David Wagler, in Family Life (1996) as quoted on Amish America, calls Romans 12:2 'the banner verse'. He says the Amish and other plain groups read it to mean Christians are to be different from the world in every part of their lives, nonconformed in thoughts, appearance and actions, resulting in distinctive attire. Mennonite historian John Roth writes that persecution reinforced a theology of nonconformity that has been central to Amish, Mennonite and Brethren identity ever since.10 sources10 sources18.

  2. P2. Nonconformity to this age must show in every part of life, appearance and dress included.

→ Conclusion. Romans 12:2 calls Christians to a visibly distinct way of life, set apart from the surrounding culture.

Strongest responses

Protestant: Anabaptist challenges P2

Plainness is not renewal. Asher Witmer, a conservative Anabaptist writing in Mennonite World Review (2020), argues that people are not transformed by refusing to wear certain clothes, and that some plain circles mistake plainness for the renewing of the mind. He reads being conformed to this world as deciding for ourselves what is good and evil.20

Protestant: Anabaptist challenges the framing

A principle that can turn legalistic. Roth himself acknowledges that the principle of nonconformity has sometimes become legalistic and oppressive and has led to divisions among Anabaptist groups, while still treating it as an important expression of faith.34

Protestant: evangelical challenges the conclusion

Not escape, but life under other controls. Peterson says Paul in Romans 12:2 does not call for escape from the world and its pressures, but for a life in the world that is impelled and controlled by other factors.6

Protestant: Reformed challenges the framing

Transforming the culture. Steven Yu, writing in Australian Presbyterian on Abraham Kuyper's neo-Calvinism, cites Romans 12:2 to argue that the gospel should transform the culture. The saved materials do not show Kuyper's own use of the verse.19

Catholic challenges the framing

Distinction without separation. The Catechism, in a paragraph that does not cite Romans 12:2, says Christians must distinguish the growth of God's Reign from the progress of culture and society, but that this distinction is not a separation; the duty to act in this world is reinforced.47

Plain assessment

Wagler and Roth document a long Anabaptist reading of the verse as a call to distinct thought, appearance and conduct. From inside the tradition, Witmer warns that plainness is not itself renewal, and Roth that nonconformity has sometimes turned legalistic and divisive. Peterson reads the verse as life in the world under other controls, Yu applies it to transforming culture, and the Catechism distinguishes God's Reign from cultural progress without separating them.

What would change this assessment: Direct monastic readings of the verse, and Kuyper's own use of it, would complete the comparison.

Assessment uses: Protestant: Anabaptist · Protestant: evangelical · Protestant: Reformed · Catholic · Named interpreters apply Romans 12:2 both to a visibly distinct communal life and to transforming culture.

Does renewing the mind mean you should stop questioning?

The cited readers limit unrenewed reason's authority but give the renewed mind work to do; none describes renewal as ceasing to question, and Hume's charge targets faith in general, not this verse.

See the argument

The strongest case

The worry rests on real texts. Luther, preaching on this verse, says Christians must follow neither the customs of the world nor their own reason or plausible theories, and must not obey the dictates of reason and desire. Calvin says Paul pulls reason down from her throne. Piper says our minds are fallen, with a bent hostile to God's supremacy, and Joyce Meyer applies the verse to disciplined minds that think in agreement with God's Word and not the devil's lies.12 sources12 sources8. Luther 190948. Calvin 184941. (translator 184921. Piper49. Meyer50. Peterson9. Aquinas36. Chester35. Peterson37. Wesley 175538. Witnesses51. Hume

  1. P1. Luther and Calvin, reading this verse, deny the believer's own reason the last word, and Owen calls it a perversion to set up reason as an umpire in matters of faith.8 48 41No listed response challenges this premise
  2. P2. Peterson reads 12:2 as implying that the human mind, apart from renewal, cannot guide a person in the life that pleases God, the conclusion he finds in Romans 1:28.50No listed response challenges this premise
  3. P3. If the unrenewed mind cannot be trusted, doubts that arise from one's own reasoning are to be set aside rather than followed.

→ Conclusion. Renewing the mind, so read, means distrusting one's own questions about faith.

Strongest responses

Catholic challenges P3

Reason repaired, not set aside. Aquinas identifies the 'sense' to be renewed as reason, by which a person judges what is to be done. Sin corrupted it, so on his reading renewal repairs reason rather than setting it aside.9

Protestant: Anglican challenges the conclusion

Anti-intellectualism is the worldliness. John Stott, as Tim Chester quotes him from Your Mind Matters, called anti-intellectualism in some Christian groups not true piety but part of the fashion of the world, and therefore a form of worldliness.36

Protestant: evangelical challenges P3

Renewed minds reason better. Peterson, following Käsemann as he reports him, writes that God has given minds to assess ethical demands, and that in the light of the new aeon Christians can do a better job with reason than the world in general does. He adds Käsemann's paradox that Christians may do what seems irrational, as God did in the cross.35

Protestant: Methodist challenges the conclusion

The highest reason. Wesley glosses reasonable service by saying a Christian acts in all things by the highest reason, inferring his own duty from the mercy of God.37

Jehovah's Witnesses challenges the conclusion

Neither blind faith nor skepticism. The Witnesses' study note on 'prove to yourselves' says Paul was advising neither blind faith nor skepticism, but testing God's requirements in a positive way in order to understand and apply them.38

Plain assessment

The texts behind the worry are real. Luther, Calvin and Owen deny unrenewed reason authority over faith, though Luther's examples are poverty, suffering and other things reason condemns, and Peterson grounds the point in Romans 1:28. Aquinas reads renewal as reason repaired, Peterson as better ethical reasoning, Stott as a rebuke to anti-intellectualism, Wesley as acting by the highest reason, and the Witnesses' note as testing, not blind faith. None of the cited readers describes renewal as ceasing to question. Hume's charge that faith subverts the understanding is aimed at Christian belief in general, not at this verse.

What would change this assessment: A named critic arguing directly that Romans 12:2 suppresses doubt, which the research did not find, would let the charge be tested in its own terms.

Background

Mercy before conduct Scholarship

Sanday and Headlam hold that the 'therefore' of 12:1 refers less to what immediately precedes than to the result of Paul's whole argument. Peterson argues that the praise of 11:33-36 leads into the appeal, whose 'therefore' should be given full force. Calvin says Paul, having shown that salvation comes from God's mercy alone, passes on to show how Christian life is to be formed. Lee Bond reports Käsemann and others reading 12:2 as a bridge from the doctrine of chapters 1-11 to the ethics of 12-16.4 sources4 sources56. Sanday 190253. Peterson57. Calvin 184958. Bond

The present age and social pressure Scholarship

Sanday and Headlam explain 'this age' from Jewish theology, which contrasted the present age with the age to come, the age of the Messiah; aion came to carry a moral sense, as here.

Comparisons: rational sacrifice and study as offering Scholarship

Peterson notes that logikos was a favourite term of the philosophers, especially the Stoics, for what belongs to reason, and that some writers advocated 'rational sacrifice' in place of traditional sacrifices. Epictetus says that as a rational creature, not a nightingale, he must praise God.

The wider argument about faith and reason Scholarship

Hume, closing his essay on miracles and writing about Christian belief in general rather than this verse, says that whoever is moved by faith to assent to it is conscious of a continued miracle that subverts all the principles of his understanding. Owen, Calvin's translator, calls it wholly a perversion to use 'reasonable service' to set up reason as an umpire in matters of faith, while in the same note calling the service consistent with the dictates of reason.51 41

Romans 12:2 · “aion: age or world”

The noun is aion, glossed age in the STEPBible data, not kosmos. Young's, the LSV and the NRSVUE have this age; the KJV, ASV, WEB, BSB, Darby, Douay-Rheims and Geneva have this world, and the NIV 'the pattern of this world'. The New World Translation has 'this system of things'. Sanday and Headlam explain the moral sense from the Jewish contrast between the present age and the age of the Messiah.7 sources7 sources2. this site's data3. Romans 12:213. this site's data4.

Romans 12:2 · “syschematizo and metamorphoo: conformed and transformed”

Syschematizo occurs in the New Testament only here and in 1 Peter 1:14; metamorphoo only here, in 2 Corinthians 3:18 and in the transfiguration accounts of Matthew 17:2 and Mark 9:2. Sanday and Headlam, following Lightfoot's distinction between schema and morphe, contrast the world's external and fleeting fashion with transformation in one's inmost nature. Peterson (1993) reports a 'strong consensus' that the two verbs are more or less synonymous in Koine Greek, while finding a difference of emphasis. J. B. Phillips' paraphrase speaks of not letting the world 'squeeze you into its own mould'.6 sources6 sources28. this site's data29. 1 Peter 1:1430. this site's data5. Sanday 19026. Peterson27.

Romans 12:1 · “logike latreia: reasonable, spiritual or intelligent worship”

The KJV and Douay-Rheims have reasonable service; the ASV, WEB and BSB spiritual service; Darby, Young's and the LSV intelligent service. The ESV and RSV have spiritual worship, the NRSVUE a reasonable act of worship and the NIV true and proper worship. Classicist Kirk Summers calls the phrase elusive and enigmatic. Logikos occurs elsewhere in the New Testament only in 1 Peter 2:2, of milk. Owen reports that Origen took it as service consonant with reason, and Chrysostom as spiritual.6 sources6 sources40. this site's data4. Romans 12:1-2 (NIV, ESV, RSV, NRSVUE), Bible Gateway7.

Romans 12:2 · “dokimazein: test, approve or discern”

The KJV, ASV and WEB have prove, the BSB test and approve, and the ESV 'by testing you may discern'. In older English prove meant test. John Owen, Calvin's 1849 translator, gives the verb's chief senses as to test, to approve what is tested and to discern, judges discern the most suitable here, and records Jerome's 'carefully search' and Theophylact's 'know'.31 4 32

Romans 12:2

BSBDo not be conformed to this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what is the good, pleasing, and perfect will of God.

KJVAnd be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.

Romans 12:2 · “Commands or a continued appeal”

The SBL Greek New Testament, Textus Receptus and Scrivener print the two verbs as commands (-esthe); the Robinson-Pierpont Byzantine text prints infinitives (-esthai), continuing the appeal of 12:1. The meaning hardly changes. Sanday and Headlam find a preponderance of evidence for the commands, citing B, L and P, the versions and most Fathers against A, D, F and G.33 5

How it has been interpreted

Tradition

How different traditions read these texts, in their own terms.

Early church: Greek · John Chrysostom — renewal through repentance

Chrysostom says Paul wrote 'be transformed' rather than 'change the fashion' to show that the world's ways are a fashion, while virtue is a real form with a natural beauty of its own. Renewal is daily: by repentance, tears, confession and good deeds, as a house is repaired when it wears. The body becomes a sacrifice when the eye looks on no evil, the tongue speaks nothing filthy and the hand does no lawless deed, and good works are needed too.14 67

Early church: Latin · Augustine — true sacrifice

AugustineAugustineA North African theologian (354–430), born at Tagaste, who served as bishop of Hippo from 396 until his death, according to the Catholic Encyclopedia.From: Portalié; PortaliéAll terms → quotes these verses in The City of God and defines a true sacrifice as every work done so that we may be united to God in holy fellowship. He applies the renewal of the mind to the soul losing the shape of earthly desire and being remoulded in the image of permanent loveliness.68

Catholic · Aquinas and the Catechism — reason repaired, prayer and worship

Aquinas explains this age as the things that pass away in time, to which a person is conformed by clinging to them in love. The 'sense' to be renewed is reason, by which a person judges what is to be done, corrupted by sin. The Catechism calls the moral life spiritual worship, with its source and summit in the Eucharistic sacrifice, and, citing Romans 12:2, says that by prayer we can discern God's will and obtain the endurance to do it.4 sources4 sources9.

Orthodox · Hieromonk Damascene — renewal of the nous

In a 2005 pastoral talk, Hieromonk Damascene says the renewal of the mind is the renewal of the nous, which Orthodox theology calls the highest faculty of the soul, the one that knows God directly. He quotes Chrysostom on daily renewal by repentance, and points the verse's transformation toward the purpose of life, unending union with God, called deification or theosis, a never-ending growth. It is a talk, not an official teaching document.70 71

Protestant: Lutheran · Martin Luther — experience against reason's verdict

Luther tells Christians to follow neither the customs of the world nor their own reason or plausible theories. His immediate examples are valuing poverty, suffering and other things that human reason condemns. God's will, he says, is ever good, though human reason imagines it evil, so Christian experience must feel, prove, test and ascertain it.8 43

Protestant: Reformed · John Calvin — the mind renewed under God's word

Calvin takes 'world' here to mean the sentiments and morals of men. The mind itself, which philosophers make the ruling power, must be renewed: Paul pulls reason down from her throne. What is good and right must be ascertained from God's commandments, and 'reasonable service' rules out whatever is attempted beyond the rule of God's word. Steven Yu, writing on Abraham Kuyper's neo-Calvinism, cites the verse to argue that the gospel should transform the culture.5 sources5 sources26. Calvin 184948. Calvin 184944. Calvin 184942.

Protestant: Anabaptist · Nonconformity, and a debate about plainness

Amish writer David Wagler, quoted on Amish America, calls Romans 12:2 'the banner verse' and says plain groups read it as requiring nonconformity in thoughts, appearance and actions, with distinctive attire. Mennonite historian John Roth traces its central place to persecution, while acknowledging that it has sometimes turned legalistic and oppressive and caused divisions. Conservative Anabaptist Asher Witmer argues that refusing certain clothes transforms no one, and that some plain circles mistake plainness for the renewing of the mind.18 34 20

Protestant: Methodist · John Wesley — the highest reason and sure trial

Wesley glosses 'reasonable service' by saying a Christian acts in all things by the highest reason, inferring his own duty from the mercy of God. He reads 'prove' as 'know by sure trial', takes the will of God as all the preceptive, or commanding, part of Christianity, and applies nonconformity to judgment, spirit and behaviour alike.37 39

Protestant: Anglican · John Stott — anti-intellectualism as worldliness

John Stott, as Tim Chester quotes him from Your Mind Matters, called anti-intellectualism in some Christian groups not true piety but part of the fashion of the world, and therefore a form of worldliness. Stott thus turns the language of Romans 12:2, the fashion of the world, against anti-intellectualism.36

Protestant: evangelical · John Piper and Joyce Meyer — the Spirit's work and a disciplined mind

Piper says our minds are not only finite and short of information but fallen, with a bent hostile to God's supremacy. From Titus 3:5 he argues that renewing the mind is first and decisively the Spirit's work, with our efforts following, through hearing the gospel, reading the Bible and meditating on Christ. Joyce Meyer, in a devotional adapted from Battlefield of the Mind, applies the verse to disciplined minds that think in agreement with God's Word and not the devil's lies.21 49

Academic (critical) · Sanday and Headlam — two ages and exact judgment

Sanday and Headlam explain 'this age' from the Jewish contrast between the present age and the age of the Messiah. Following Lightfoot, they contrast the world's external and fleeting fashion with transformation in one's inmost nature, and they say renewal makes the intellect, the seat of moral judgement, true and exact in judging spiritual and moral questions.24 25 5

Jehovah's Witnesses · The New World Translation — testing God's requirements

The New World Translation renders the verse 'stop being molded by this system of things', and its study note gives aion the basic meaning age, glossing the system as the standards, customs and styles of the Roman world. Its note on testing says Paul was advising neither blind faith nor skepticism, but testing God's requirements in order to understand and apply them; its note on logikos speaks of the God-given power of reason.38

Where else the Bible mentions it

Text
  • Matthew 17:2 Jesus is transfigured before Peter, James and John; transfigured translates the same verb as 'be transformed' in Romans 12:2. Piper uses the link to argue that nonconformity is not primarily external avoidance of worldly behaviours, while including it.

    2There He was transfigured before them. His face shone like the sun, and His clothes became as white as the light.

  • 1 Peter 1:14 The only other New Testament use of the verb for 'be conformed': readers are told not to be conformed to the passions of their former ignorance.

    14As obedient children, do not conform to the passions of your former ignorance.

  • Titus 3:5 The only other New Testament use of the noun for 'renewing', where it is the renewal of the Holy Spirit. Piper argues from it that renewing the mind is first and decisively the Spirit's work.

    5He saved us, not by the righteous deeds we had done, but according to His mercy, through the washing of new birth and renewal by the Holy Spirit.
