1 Corinthians 7:13-15

New Revised Standard Version, Anglicised

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. ¹⁵ But if the unbelieving partner separates, let it be so; in such a case the brother or sister is not bound. It is to peace that God has called you.^[a]
