I should also correct the formulation of your question by referring to the words of institution. IIt was words of the Savior by which He instituted the Sacrament.
Did the bread and wine become the literal flesh and blood of Jesus at the Last Supper when Christ instituted it with His disciples and did they eat it as the actual literal flesh and blood as the Catholic church teaches?
Did Christ eat and drink His own body and blood in violation of the OT Law that forbade it?
Leviticus 7:26 & 27 Moreover, you shall eat no blood whatever, whether of fowl or of animal, in any of your dwelling places. Whoever eats any blood, that person shall be cut off from his people."
Leviticus 17:10-16 10"If any one of the house of Israel or of the strangers who sojourn among them eats any blood, I will set my face against that person who eats blood and will cut him off from among his people. 11 For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. 12Therefore I have said to the people of Israel, No person among you shall eat blood, neither shall any stranger who sojourns among you eat blood.
13"Any one also of the people of Israel, or of the strangers who sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with earth. 14For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off. 15 And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean. 16But if he does not wash them or bathe his flesh, he shall bear his iniquity."
Deuteronomy 12:23 Only be sure that you do not eat the blood, for the blood is the life, and you shall not eat the life with the flesh.
Did Jesus break the OT law by eating His own flesh and blood at the time of the Last Supper?
