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 by the Word of God, had both 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.
of course what Justin Martyr described and thank you to rnmomof7 for posting is the Catholic Mass.
to all followers of the 16th century tradition of men, Justin faithfully describes to you the Apostolic Faith...the Eucharist is the Body of Christ.
So you think Jesus sinned by eating blood ey?
