“It remains to speak of that spiritual bread which also is the object of this petition of the Lord’s Prayer, which takes in everything that is necessary for the health and safety of the spirit and soul. Just as the food by which the body is nourished is of various sorts, so is the food which preserves the life of the spirit and soul not of one kind. Thus, the word of God is the food of the soul” (”Roman Catechism,” “loc. cit.,” 18).
