Origen

“ For if there are two laws, the law in our members warring against the law of the mind, and the law of the mind, [1] we must say that the law of the mind—that is, the spiritual—is man, to whom the soul was given by God as wife, that is, to the man who is law, according to what is written, “A wife is married to a man by God;” [2] but the other is a paramour of the soul which is subject to it, which also on account of it is called an adulteress. ”

“ But this very saying, “So then while her husband liveth, she shall be called an adulteress,” we have brought forward, wishing clearly to show why in answer to the Pharisees and Sadducees who were tempting Him and asking Him to show them a sign from heaven, He said not only “a wicked generation,” but an “adulterous” generation. [8] In a general way, then, the law in the members which wars against the law of the mind, [9] as a man who is an adulterer, is an adulterer of the soul. ”

“ But now also every power that is hostile, which gains the mastery over the human soul, and has intercourse with it, commits adultery with her who had a bridegroom given to her by God, namely, the Word. ”
