For it is sanctified through the word of God and prayer.
Justly, therefore, does Paul connect lawful enjoyment with “the word”, by which alone we regain what was lost in Adam; for we must acknowledge God as our Father, that we may be his heirs, and Christ as our Head, that those things which are his may become ours. Hence it ought to be inferred that the use of all the gifts of God is unclean, unless it be accompanied by true knowledge and calling on the name of God; and that it is a beastly way of eating, when we sit down at table without any prayer; and, when we have eaten to the full, depart in utter forgetfulness of God.
