In Moses’ Law, God restricted Israel from eating blood. A few things are readily obvious in this. First, this ought not to tangle you up with guilt if you prefer your steaks done rare. Rather, this guarded Israel from participating in the occultism of the demon worshipping nations around them. The literal blood-thirst of paganism imagined that drinking a slain beast’s blood would impart the vitality of that beast to you. Even more darkly, the heathen practice of drinking the blood of other humans was a twisted hope for grasping after eternal life.
The Altar of the Lord alone was the lawful place to offer up sacrificial blood. To partake of ritual blood for yourself would be to make a covenant claim that you can assuage your own guilt. If your sin demands death, offering another’s blood to yourself is a claim to sovereignty, setting yourself up as your own judge & pretentiously becoming your own mediator. This is just part of why God forbid this practice. The blood belonged on His Altar, reminding the worshipper that guilt deserved death, but God received the creature’s blood as the worshipper’s substitute. But this arrangement only worked because God covenanted with His people, establishing these terms according to His sovereign will.
When Christ came as the fulfillment of all these laws & ordinances, He surprises us with a command to drink wine as a covenant sign of His blood. While Moses outlawed the partaking of ritual blood, Jesus invites us to drink this covenant blood, every last drop.
Life is in the blood. Until Christ, the blood of guiltless beasts was required. But now, an eternal sacrifice has been made. You drink this covenant sign of the blood of another, and it’s not some dark & twisted way to wrest eternal life from God’s Hand. Because this blood was shed by the Son of God’s own hand.
So come in faith and welcome to Jesus Christ…
