Jer 5, 7 Your sons have forsaken me

(Jer 5, 7) Your sons have forsaken me

[7] Why should I pardon you these things? Your sons have forsaken me, they swear by gods that are not. I fed them, but they committed adultery; to the harlot's house they throng.

(CCC 2380) Adultery refers to marital infidelity. When two partners, of whom at least one is married to another party, have sexual relations - even transient ones - they commit adultery. Christ condemns even adultery of mere desire (Cf. Mt 5:27-28). The sixth commandment and the New Testament forbid adultery absolutely (Cf. Mt 5:32; 19:6; Mk 10:11; 1 Cor 6:9-10). The prophets denounce the gravity of adultery; they see it as an image of the sin of idolatry (Cf. Hos 2:7; Jer 5:7; 13:27).
