This is your interpretation... that you are trying to foist upon Catholic doctrine. The Church is very clear that He is not re-sacrificed. Again, do your homework before stating what the Church does or doesn't teach. You are correct, however, that His Body, Blood, Soul, and Divinity are truly present. Thank God!
I like Scott Hahn's explanation that the Eucharist is a 're-presentation' of His death upon the cross for our redemption. He made there, by His one oblation of Himself once offered, a full perfect, and sufficient sacrifice, oblation, and satisfaction, for the sins of the whole world.
