A biblically consistent affirmation is that Jesus is "truly God and truly human", not a measurable 100% one way or the other. The literal interp of the Lord's Table (the sacrament) is called transubstantiation and is predominately a Catholic belief... I am not Catholic but I've been a studious believer for over a decade and I'd say it's not cannibalism because it's not real... The sacrament isn't about eating Jesus' literal body and blood.
