But some from the sect of the Pharisees who had believed [in Jesus as the Messiah] stood up and said, “It is necessary to circumcise the Gentile converts and to direct them to observe the Law of Moses.”

Brothers and sisters, you know that those of the household of Stephanas were the first converts in Achaia, and that they have devoted themselves for ministry to God’s people—now I urge you

Before certain men came from James, he used to eat [his meals] with the Gentiles; but when the men [from Jerusalem] arrived, he began to withdraw and separate himself [from the Gentile believers], because he was afraid of those from the circumcision.

But we should and are [morally] obligated [as debtors] always to give thanks to God for you, believers beloved by the Lord, because God has chosen you from the beginning for salvation through the sanctifying work of the Spirit [that sets you apart for God’s purpose] and by your faith in the truth [of God’s word that leads you to spiritual maturity].
