1 Corinthians 7:12-15  English Standard Version

¹² To the rest I say (I, not the Lord) that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her. ¹³ If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him. ¹⁴ For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. ^(A)Otherwise your children would be unclean, but as it is, they are holy. ¹⁵ But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you^{[a] (B)}to peace.
