1 Corinthians 7:12-15

Moffatt(i) 12 To other people I would say (not the Lord): — if any brother has a wife who is not a believer, and if she consents to live with him, he must not put her away; 13 and if any wife has a husband who is not a believer, and if he consents to live with her, she must not put her husband away. 14 For the unbelieving husband is consecrated in the person of his wife, and the unbelieving wife is consecrated in the person of the Christian brother she has married; otherwise, of course, your children would be unholy instead of being consecrated to God. 15 (Should the unbelieving partner be determined to separate, however, separation let it be; in such cases the Christian brother or sister is not tied to marriage.) It is to a life of peace that God has called us.
