Matthew 26:29 I tell you I will not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.”
Mark 14:25 Truly, I say to you, I will not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God.”
Luke 22:18 For I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.”
John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.
And then there's this....
Matthew 23: 8-10 But you are not to be called rabbi, for you have one teacher, and you are all brothers. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called instructors, for you have one instructor, the Christ.
Why do Catholics disobey the clear, plain command of Jesus?
[64] The flesh profiteth nothing: Dead flesh separated from the spirit, in the gross manner they supposed they were to eat his flesh, would profit nothing. Neither doth man’s flesh, that is to say, man’s natural and carnal apprehension, (which refuses to be subject to the spirit, and words of Christ,) profit any thing. But it would be the height of blasphemy, to say the living flesh of Christ (which we receive in the blessed sacrament, with his spirit, that is, with his soul and divinity) profiteth nothing. For if Christ’s flesh had profited us nothing, he would never have taken flesh for us, nor died in the flesh for us.
