“To eat and drink with thanksgiving to God all that is served up or prepared for one is not in any way opposed to the rule of knowledge. For everything is very good (Genesis 1.31).
But voluntarily to abstain from what is agreeable and abundant is a sign of great discernment and higher knowledge. We do not readily despise the delights of this life if we do not taste with complete satisfaction the sweetness of God.”St. Diadochus of Photike, Gnostic Chapters, 44.
