Jesus our Savior…

As by the Word of God, Jesus our Savior was made Flesh and had both Flesh and Blood for our salvation, so also the food which has been blessed by the word of prayer instituted by Him is both the Flesh and Blood of Jesus Incarnate.
–Saint Justin Martyr (100-165)

The Church received…

The Church, spread throughout the whole world, received this preaching and this faith and now preserves it carefully, dwelling as it were in one house. Having one soul and one heart, the Church holds this faith, preaches and teaches it consistently as though by a single voice. For though there are different languages, there is but one tradition.
–Saint Irenaeus (late 2nd Century)
