1 Corinthians 7:12-14

New Revised Standard Version Catholic Edition

¹² To the rest I say—I and not the Lord—that if any believer^[a] has a wife who is an unbeliever, and she consents to live with him, he should not divorce her. ¹³ And 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 through his wife, and the unbelieving wife is made holy through her husband. Otherwise, your children would be unclean, but as it is, they are holy.
