1 Corinthians talks about a Christian who has an unbelieving mate. At one point, Paul says, “But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases” (v. 15). Jesus said in Matthew 5:32 and Matthew 19:8-9 that one can divorce a spouse only in the case of marital unfaithfulness. Does Paul advocate divorce or abandonment?
1 Corinthians 7:10 - 16
ESV - 10 To the married I give this charge (not I, but the Lord): the wife should not separate from her husband 11 (but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.
