New Defender's Study Bible Notes
3:2 dogs. The epithet of “dogs” was sometimes applied by Jews to Gentiles in general, but Paul would not do this; indeed, he was writing to Gentile Christians. In the Old Testament, sodomites were called dogs (Deuteronomy 23:17-18). In view of Paul’s strong condemnation of this typically pagan Gentile sin (Romans 1:25-27; I Corinthians 6:9), it is probable that Paul’s warning here had reference to the sin of homosexuality or bestiality.
