 We talk about the body of Christ, like the priest says when he puts the host on your tongue, or if you receive in the hand, he says the body of Christ. That's just language. It doesn't mean that it's, this is just the body of Christ, like a body that has no blood in it. That's not what it means. So when he says, unless you drink my, or eat my flesh and drink my blood, what the church teaches is that it's contained, all of him is contained in either form.
