Thematic Bible: Unbelieving spouses

I command the married-not I, but the Lord-a wife is not to leave her husband. But if she does leave, she must remain unmarried or be reconciled to her husband-and a husband is not to leave his wife. But to the rest I, not the Lord, say: If any brother has an unbelieving wife, and she is willing to live with him, he must not leave her. read more.
Also, if any woman has an unbelieving husband, and he is willing to live with her, she must not leave her husband. For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the Christian husband. Otherwise your children would be unclean, but now they are holy. But if the unbeliever leaves, let him leave. A brother or a sister is not bound in such cases. God has called you to peace. For you, wife, how do you know whether you will save your husband? Or you, husband, how do you know whether you will save your wife?
