1 Corinthians 6:18

That is the truth, of which the other is the lie. Just as in the truth man cannot separate himself from the Lord, for there is but one Spirit, so in the false, in the carnal action, man cannot separate himself from the sin to which he surrenders, he sins not against another only, nor does the wrong of his action merely affect that which is outside himself. He cannot excuse himself by saying “it has nothing to do with my true being, it is inherent in the body only, and I disclaim its connection with me, though as a physical being I am forced by the power of Nature to submit to it, even as I am forced by other appetites to eat and drink!” The reasoning is false.
