Jesus, by catholic heretical reasoning that the chalice contained the Blood of Jesus, was either lying to His disciples calling the cup contents wine but giving them blood, in violation of the Law as recorded in Leviticus (unlikely since He was not yet sacrificed for sin so He would not have made His disciples break the Law), OR Jesus turned the contents back into wine just before He poured the last out and made His proclamation about not drinking the fruit of the vine at that Passover ending. In the latter case He would still have caused His disciples to violate the Law before He went to the Cross as the Lamb of God, in which case He would not be without spot or blemish for the next Day sacrifice of Himself for the sins of the world.
Since we have the words of Messiah Himself calling the cup contents WINE, which is it, catholic? Did Jesus lie to His disciples (or is catholiciism in error calling the contents blood camouflaged as wine), or did Jesus turn the blood back into wine before calling it wine as He poured it out [ wine according to Luke's iteration of the Passover Seder]?
The solution to such a seeming dilemma is to read the text as it is, with JESUS identifying the cup contents as wine, fruit of the vine, demonstrating the sacred metaphor for His disciples. This reading then does not contradict the LAw and aligns with the vast majority of scriptures where Jesus used metaphor to confound the chasers after signs and the twisters, but then clarified the teachings for His faithful disciples.
Catholicism as practiced is not Christianity. It is another religion, a religion in which pagan rites and practices (like imagining the adherents eat the actual body and blood and thus the divinity of the pagan god) are installed over the Gospel of God's Grace in Christ toward humankind. This heretical installation empowers an institution of priests and Bishops and a pope, but does not lead to the narrow gate to Heaven.
As final example, the following assertion is contradictory to what The Bible teaches, yet is at the heart of the catholic religion: "Sanctification is the process of drawing closer to Christ both in faith and in works, which results in salvation at the time of death." post #574
The catholic apologist erringly assigns sanctification as a works based means to deserve salvation at the time of death. God tells us differently in the Bible, that Salvation is the moment we are born from above, followed by His process of sanctifying us during the remaining lifetime of being alive in Christ, as a member of The Body Of Christ.
For how many generations have Christians kept the Passover ? And this day shall be unto you for a memorial; and ye shall keep it a feast to the Lord throughout your generations; ye shall keep it a feast by an ordinance for ever. Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

And the Lord said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof: But every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof. A foreigner and an hired servant shall not eat thereof. In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof. All the congregation of Israel shall keep it. And when a stranger shall sojourn with thee, and will keep the passover to the Lord, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof. One law shall be to him that is homeborn, and unto the stranger that sojourneth among you. Thus did all the children of Israel; as the Lord commanded Moses and Aaron, so did they.

And it was magically transmogrified into the newly invented Communion; which is NOT listed at all in Acts 15.
What seems to keep being missed is that the Council of Jerusalem reiterated the ban of drinking blood for Christians. There was no exception made for when the Lord's Supper was observed.
