But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God has called us to peace.
All Commentaries on 1 Corinthians 7:15 Go To 1 Corinthians 7
Ambrosiaster
AD 400
A marriage contracted without devotion to God is not binding, and for that reason it is not a sin if it is abandoned because of God. But the unbelieving partner sins both against God and against the marriage, because he or she is unwilling to live in a marriage relationship dedicated to God. It is not right to go to court over this because the one who leaves the marriage is doing so out of hatred for God, and for this reason he or she is not to be considered worthy of such attention. Commentary on Paul’s Epistles.
