Um, Jesus was not present on Earth at AD 350. Thus, the invocation is required.<quoted text>
Heretics abstain from the Eucharist and from prayer, because they do not confess that the Eucharist is the Flesh of our Savior Jesus Christ." St. Ignatius of Antioch ("Epistle to the Smyrneans," c. 105 A.D.)
"The bread and the wine of the Eucharist before the holy invocation of the adorable Trinity were simple bread and wine, but the invocation having been made, the bread becomes the Body of Christ and the wine the Blood of Christ." St. Cyril of Jerusalem ("Catechetical Lectures," 350 A.D.)
Dan, see how long it took you change from just believing because Jesus said so and then to it needing a invocation? There is a reason many don't believe what you say, it changes.
17After taking the cup, he gave thanks and said,“Take this and divide it among you. 18For I tell you I will not drink again from the fruit of the vine until the kingdom of God comes.”
19And he took bread, gave thanks and broke it, and gave it to them, saying,“This is my body given for you; do this in remembrance of me.”
20In the same way, after the supper he took the cup, saying,“This cup is the new covenant in my blood, which is poured out for you.
Congratulations-yours is the worst argument I've ever seen respective to the rejection of Christ's teaching of His Real Presence in the Eucharist.
