1 Corinthians 7

10 These are my instructions to those who are married—in fact not from me but the Lord: The wife should not leave her husband 11 (or if she does, she should not remarry, or she should return to her husband); and the husband should not leave his wife.*7:11. One particular problem in the early church was of one spouse becoming Christian, and how then to relate to the non-Christian spouse. This seems to be what is addressed here.
