[6.222.11] But I got up and said to them: "Yes, I also mean the likes of you! You blind fools! What goes through the mouth in and through the mouth into the body and leaves the body again through the natural way, does not defiles a person; however, what comes out of the mouth from the heart, like evil thoughts, bad and scurrilous talk, dishonouring, perjury, lies of all kind, deception, jealousy, stinginess, fornication, whoring and adultery, gormandising and gluttony, also with your pure foods, really defiles the whole person!
[6.222.12] Look it up in the scriptures and you will find why Moses has recommended the enjoyment of only cleans foods! He did this because of your too great meat voraciousness and because of your unbound sensuousness and lecherousness. But I say now, that for him who is pure in the heart, also everything else is pure, however, to the impure everything else is impure.
