The Priestly and Deuteronomic Torah absolutely forbids eating blood as a perpetual statute (Gen 9:4; Lev 3:17; 7:26-27; 17:10-14; 19:26; Deut 12:16, 23), and the apostolic decree in Acts 15 reaffirms that prohibition for Gentile Christians. John 6:53-56, however, has Jesus commanding that his followers eat his flesh and drink his blood to have eternal life. The Torah bans blood-drinking outright; the Johannine Jesus makes it the condition of salvation.

He who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is food indeed, and my blood is drink indeed. He who eats my flesh and drinks my blood lives in me, and I in him.

Therefore I have said to the children of Israel, “No person among you may eat blood, nor may any stranger who lives as a foreigner among you eat blood.” “ ‘Whatever man there is of the children of Israel, or of the strangers who live as foreigners among them, who takes in hunting any animal or bird that may be eaten, he shall pour out its blood, and cover it with dust.

It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Leans toward reconciliation
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The Torah's prohibition of blood is one of its most emphatic and most repeated commands. It is grounded in Genesis 9:4 (given to Noah, hence binding on all humanity in the rabbinic Noahide scheme), reinforced as a "perpetual statute" in Leviticus 3:17 and 7:26-27, and given its theological rationale in Leviticus 17:11: "the life of the flesh is in the blood, and I have given it to you upon the altar to make an atonement for your souls." Blood is forbidden to humans precisely because it is sacrificially charged and belongs to God. Deuteronomy 12:16, 23 repeats the ban in the context of profane slaughter, and Acts 15:20, 28-29 shows the apostolic council reaffirming abstention "from blood" for Gentile believers. Against this stands John 6:53-56, where Jesus makes drinking his blood the condition of eternal life: "Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you."
The standard Christian responses divide. A symbolic reading (Calvin and much of the Reformed tradition) takes John 6 as metaphor for believing appropriation of Christ, so no literal blood is consumed. A sacramental reading (Raymond Brown, with eucharistic qualification) takes the referent to be the eucharistic flesh and blood of Christ, not a prohibited animal; the Levitical statute regulates the slaughter and consumption of animal blood within Israel's cult, an entirely different category from participation in the new covenant. Blomberg and others add that the apostolic decree addressed table-fellowship and idol-associated practices, not Christology. On its own terms each reading coherently keeps John 6 outside the letter of Leviticus: the object prohibited (animal blood, drained at slaughter) is simply not the object John commands (the person of Christ, sacramentally or figuratively received).
That defense succeeds at the level of intra-Christian systematic theology, but it understates the deliberate theological collision John stages. Leviticus 17:11 forbids blood because it is the locus of atoning life that belongs to God; John 6 commands drinking blood because it is the locus of atoning life now offered to the believer. John inverts the very logic that grounds the prohibition. Jacob Milgrom's analysis of Leviticus 17 emphasizes how absolute and life-theological the ban is, and Jonathan Klawans shows how thoroughly blood-as-life structured Israelite sacrificial thought — which is why the Johannine demand would land as scandal on a Jewish ear. John's own narrator dramatizes the scandal: "This is an hard saying; who can hear it?" (6:60), and many disciples leave. The shock is the point; the evangelist is not trying to stay inside Leviticus but to provoke a confrontation with it. Keener notes the eucharistic resonance while acknowledging the offense the language carried.
The Acts datum sharpens rather than relieves the difficulty. The Jerusalem council, presumably already celebrating the eucharist, nonetheless retained the blood prohibition for Gentiles (Acts 15:20, 29). Joseph Fitzmyer treats the decree as upholding the Levitical "stranger in your midst" statutes (Lev 17-18) to enable Jewish-Gentile table fellowship. That the early church could simultaneously practice a eucharist and forbid blood suggests either that it did not read John 6 as literal blood-consumption (consistent with the symbolic/sacramental defense) or that the Johannine tradition — John being the latest gospel — had not yet shaped its halakhic reasoning. Either way, the formal contradiction between a literal letter-of-Leviticus reading and a literal letter-of-John-6 reading is real; it dissolves only once one grants that John 6 operates in a different register than dietary law.
Where the critical reading lands: harmonizable on the standard symbolic/sacramental distinction (different object, different register), but only by conceding that John deliberately and provocatively reworks the very blood-theology Leviticus enshrines.
