We
see that the Savior took the bread in His hand, and when He had given
thanks He said: “This is my body....” And we see that it is not
equal or similar to either a corporeal image, or the invisible Deity,
or the arrangement of the members of the body. For it is of rounded
shape and without feeling as far as its power is concerned. But He
wanted to say by grace: “This is my body...” and no one should
refuse to believe this statement. For he who does not believe that He
is truthful, as He Himself has said, cuts himself off from grace and
salvation. But what we have heard, that we believe, namely, that it
is His body and blood.
– Saint
Epiphanius of Salamis
