Theophylact of Ohrid, on Rom 14:22

“Hast thou faith? Have it to thyself before God. Blessed is he that condemneth not himself in that which he alloweth.”

“Here he secretly hints that the mature one was displaying his maturity out of vainglory. He says: you want to show me that you are mature in faith regarding food, believing that everything is good and clean? Do not show me, but be content with the testimony of conscience before God, to Whom you show this. Even if no one else sees your blessedness, be content with yourself, if you yourself do not condemn yourself and your conscience does not condemn you in a matter that you have approved or chosen. Understand this only concerning the present subject, that is, concerning food.”
