1 Corinthians 7:12

Irenaeus Against Heresies Book IV

But why say I these things concerning the Old Testament? For in the New also are the apostles found doing this very thing, on the ground which has been mentioned, Paul plainly declaring, But these things I say, not the Lord."[180]

Tertullian To His Wife Book II

the ground of that passage of the first (Epistle) to the Corinthians, where it is written: If any of the brethren has an unbelieving wife, and she consents to the matrimony, let him not dismiss her; similarly, let not a believing woman, married to an unbeliever, if she finds her husband agreeable (to their continued union), dismiss him: for the unbelieving husband is sanctified by the believing wife, and the unbelieving wife by the believing husband; else were your children unclean."[9]
