Saying, Thou wentest in to men uncircumcised, and didst eat with them.

People's New Testament

11:3 Thou... didst eat with them. This was a positive violation, not of the laws of Moses, but of the rules of the orthodox Jews. Though Peter laid aside his Jewish exclusiveness at Caesarea, he at least once afterwards relapsed (Gal 2:12).

Jamieson-Fausset-Brown Bible Commentary

3, 4. Thou wentest in . But Peter rehearsed the matter, &c.-These objectors scruple not to demand from Peter, though the first among the apostles, an explanation of his conduct; nor is there any insinuation on Peter's part of disrespect towards his authority in that demand-a manifest proof that such authority was unknown both to the complainers and to himself.

Matthew Henry's Concise Commentary

11:1-18 The imperfect state of human nature strongly appears, when godly persons are displeased even to hear that the word of God has been received, because their own system has not been attended to. And we are too apt to despair of doing good to those who yet, when tried, prove very teachable. It is the bane and damage of the church, to shut out those from it, and from the benefit of the means of grace, who are not in every thing as we are. Peter stated the whole affair. We should at all times bear with the infirmities of our brethren; and instead of taking offence, or answering with warmth, we should explain our motives, and show the nature of our proceedings. That preaching is certainly right, with which the Holy Ghost is given. While men are very zealous for their own regulations, they should take care that they do not withstand God; and those who love the Lord will glorify him, when made sure that he has given repentance to life to any fellow-sinners. Repentance is God's gift; not only his free grace accepts it, but his mighty grace works it in us, grace takes away the heart of stone, and gives us a heart of flesh. The sacrifice of God is a broken spirit.
