Christians often practice a tradition known as communion, which involves eating bread and drinking wine in a symbolic ritual of remembrance of what Jesus did for us. This was based on his last supper, and the communion elements reveal the true meaning of the Passover story. Transubstantiation, the idea that the communion bread turns into Jesus’ literal flesh, and the wine transforms his literal blood, is not supported by biblical evidence. Blood drinking is not only forbidden in the Noahide covenant (Gen 9:3-4) and the Sinaitic covenant (Lev 7:26-27, 17:24, 19:26, Deut 12:16-25, 15:23), but also in the Messianic covenant (Acts 15:19-21). This is a sin for everyone, both Jew and Gentile, for all time from the beginning to the end.
