And if a woman has an unbelieving husband and he consents to dwell with her, she must not divorce him.
And if a woman divorces her husband and gets married to another, she commits adultery.”
Now to the rest I say this (I, not the Lord): If any brother has an unbelieving wife, and she consents to dwell with him, he must not divorce her.
For the unbelieving husband is sanctified through his wife, and the unbelieving wife is sanctified through her husband. Otherwise your children would be unclean, but as it is, they are holy.
