John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
The command against eating blood still stands.
“Of course Catholics like to ingnore the fact that He said it was spirit rather than physical.”
He never says that. If we use your interpretation, then Jesus never had flesh - or are you going to claim his “flesh profiteth nothing”? Jesus had flesh. If He didn’t, then He could not have died on the Cross and none of us are redeemed.
“The command against eating blood still stands.”
Not when its Jesus’ blood and He commands us to have it.
I guess some would assert the Holy Spirit didn't agree with God? That's strange, since the Holy Spirit IS God:
"For it seemed good to the Holy Spirit and to us to lay upon you no greater burden than these essentials: that you abstain from things sacrificed to idols and from blood and from things strangled and from fornication; if you keep yourselves free from such things, you will do well. (Acts 15:28,29)
