Galatians 2:14

“But when I saw that they walked not uprightly, etc..] Or “did not foot it aright”; or “walked not with a right foot”: they halted, as the Jews of old did, between two opinions, being partly for God, and partly for Baal; so these seemed, according to their conduct, to be partly for grace, and partly for the works of the law; they seemed to be for joining Christ and Moses, and the grace of the Gospel, and the ceremonies of the law together; they did not walk evenly, were in and out, did not make straight paths for their feet, but crooked ones, whereby the lame were turned out of the way; they did not walk in that sincerity, with that uprightness and integrity of soul, they ought to have done:…”

“walked not uprightly--literally, "straight": "were not walking with straightforward steps." Compare Gal 6:16. truth of the gospel--which teaches that justification by legal works and observances is inconsistent with redemption by Christ. Paul alone here maintained the truth against Judaism, as afterwards against heathenism (Ti2 4:16-17). Peter--"Cephas" in the oldest manuscripts before . . . all-- (Ti1 5:20). If thou, &c.--"If thou, although being a Jew (and therefore one who might seem to be more bound to the law than the Gentiles), livest (habitually, without scruple and from conviction, Act 15:10-11) as a Gentile (freely eating of every food, and living in other respects also as if legal…”

“But when I saw that they walked not uprightly - To walk, in the Scriptures, is usually expressive of conduct or deportment; and the idea here is, that their conduct in this case was not honest. According to the truth of the gospel - According to the true spirit and design of the gospel. That requires perfect honesty and integrity; and as that was the rule by which Paul regulated his life, and by which he felt that all ought to regulate their conduct, he felt himself called on openly to reprove the principal person who had been in fault. The spirit of the world is crafty, cunning, and crooked. The gospel would correct all that wily policy, and would lead man in a path of entire honesty and…”

“I said to Cephas before them all - See Paul single against Peter and all the Jews! If thou being a Jew, yet livest, in thy ordinary conversation, after the manner of the gentiles - Not observing the ceremonial law, which thou knowest to be now abolished. Why compellest thou the gentiles - By withdrawing thyself and all the ministers from them; either to judaize, to keep the ceremonial law, or to be excluded from church communion ? Galatians 2:15”

“2:14-21 The actions of Peter and the others implied that faith in Christ was not enough. Paul eloquently argues against such a compromise of the truth of the gospel message, showing that the law plays no role in defining a Christian’s position before God, which is by grace through faith (Eph 2:8-9). • It is not clear where Paul’s public rebuke of Peter ends and his message to the Galatians resumes (see study note on Gal 2:16). While Paul was recounting his address to Peter, he was also speaking to the Galatians. His rebuke of Peter was also a rebuke of them (see 3:1). 2:14 By living like a Gentile—eating with Gentiles and not observing Jewish food laws—Peter communicated God’s acceptance of…”
