1 Corinthians 7:12-16 Revised Standard Version (RSV)
12 To the rest I say, 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 consecrated through his wife, and the unbelieving wife is consecrated through her husband. Otherwise, your children would be unclean, but as it is they are holy. 15 But if the unbelieving partner desires to separate, let it be so; in such a case the brother or sister is not bound. For God has called us[a] to peace. 16 Wife, how do you know whether you will save your husband? Husband, how do you know whether you will save your wife?
