Speaking of Communion (Lord's Supper, Eucharist); the idea that liturgical faiths have that the bread and wine are literally Jesus's flesh and blood and that partakers are eating his literal flesh and literal blood. I can see it being a memorial that has value as a sacrament simply because Jesus says so, but to insist that it's literal flesh and blood seems like a kind of cannibalism. I don't know how else to put this, but I admit to finding it a bit disturbing.
