4 But when you have gotten the three loaves, that is, to feed on and understand the Trinity, you have that whereby you may both live yourself, and feed others. Now you need not fear the stranger who comes out of his way to you, but by taking him in may make him a citizen of the household: nor do you need fear lest you come to the end of it. That Bread will not come to an end, but it will put an end to your indigence. It is Bread, God the Father, and it is Bread, God the Son, and it is Bread, God the Holy Ghost. The Father Eternal, the Son Coeternal with Him, and the Holy Ghost Coeternal. The Father Unchangeable, the Son Unchangeable, the Holy Ghost Unchangeable. The Father Creator, and the Son, and the Holy Ghost. The Father the Shepherd and the Giver of life, and the Son, and the Holy Ghost. The Father the Food and Bread eternal, and the Son, and the Holy Ghost. Learn, and teach; live yourself, and feed others. God who gives to you, gives you nothing better than Himself. O you greedy one, what else were you seeking for? Or if you seek for anything else, what will suffice you whom God does suffice not?
