It was that mass murderer of Christians and Jews, Pope Innocent III, who by decree in A.D. 1215 made the Mass as a “sacrifice” an official dogma. For that to be so, Catholicism [1] relies upon its central magic: transubstantiation. “The priest is indispensable, since he alone by his powers can change the elements of bread and wine into the body and blood of Christ.”

Catholicism [1] boasts that it takes Christ literally when He said, “Except ye eat the flesh of the Son of man and drink his blood, ye have no life in you” (John:6:53Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
See All... [2]). Yet He is not taken literally when He calls Himself “the true vine” and His followers “branches” (John:15:1I am the true vine, and my Father is the husbandman.
See All... [3],5); or when He says He is “the shepherd” and “the door” and his followers “sheep” (John:10:9I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
See All... [4],14, etc.). If He is speaking literally, then those who eat His flesh and drink His blood will literally “never hunger [or] thirst” again (John:6:35And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
See All... [5]). EWTN told of Teresa Newman, who “from 1926 to 1962 never ate anything except the Eucharist,” thus “proving what Jesus said.” However, that promise was for anyone, not a few “saints.” Christ’s words make sense only if by eating He meant believing and if he referred to spiritual and eternal life, not a mere flesh-and-blood physical life on this earth.
