You're still ignoring part of my argument. If Christ said, "Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you," then to say that He merely evaluates your heart means you're not looking at the entire picture. It seems very clear that Christ was a stickler on this point.
And the thief on the cross next to Jesus' received the Eucharist when exactly?
