1 Corinthians 7:17

Each one should go on. The false teacher at Corinth (who was probably one of the Circumcision Party) taught that when you became a Christian, all former moral and political obligations vanished. This caused some wives to abandon their marriages (1 Corinthians 7:10-11), and some men to quit their jobs and beg the church to support them (1 Thessalonians 4:11-12; 2 Thessalonians 3:6-15). Paul says that every Christian should fulfill all the moral and political obligations which he had before becoming a Christian, unless he can change his condition lawfully.
