[Cronos]

So, SR, do read rather than excerpting. Now note you posted the cuts of the Early Fathers first. Read these if you want

Justin Martyr,First Apology,66(A.D. 110-165),in ANF,I:185
"For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Saviour,having been made flesh and blood for our salvation,so likewise have we been taught that the food which is blessed by the prayer of His word,and from which our blood and flesh by transmutation are nourished,is the flesh and blood of that Jesus who was made flesh."

[Natural Law]

"So, SR, do read rather than excerpting."

One only needs a single excerpt from Matthew 6:11 to accept the Real Presence:

"Ton arton hêmôn ton epiousion" (Give us today our supersubstantial bread).

Peace be with you.
