Refresh my memory: which Scripture passage states that Jesus himself consumed the bread after he blessed it and gave it to his disciples?
Perhaps you should become more familiar with the Scriptures and Catholic teaching before you make such childishly embarrassing statements as if nobody in 2000 years ever thought about it before.
Not only does it indicate He did drink but indicated it was not His real literal blood.
Matthew 26:27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; 28 For this is my blood of the new testament, which is shed for many for the remission of sins. 29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
You asked, “Which Scripture passage states that Jesus himself consumed the bread after he blessed it and gave it to his disciples?”
CynicalBear provided the answer in comment 48. Do you care to listen to the words of Scripture, which describe Jesus and His disciples celebrating a very special Passover, or do you prefer to believe the heresy that the bread was LITERALLY Jesus’ body?
The Apostle Paul understood that the bread and wine were tokens to remember Christ’s death and resurrection, but were not His literal flesh and blood. Consider 1 Cor. 11:26, in which Paul refers to the bread as ... “bread.”
