"And non-Catholic Christians, like yourself, believe is something very close to this in terms of our justification before God through Christ Jesus. For, as St. Paul says in Scripture, "In Christ, we are made into a 'new creation'." Now, clearly, this does not apply to our form – our "physical properties", since we don't look any different; and the world does not see any obvious physical change in a person when he or she becomes a believer in Christ. However, according to the words of Scripture, we know that a metaphysical change HAS taken place – that the former sinner has been re-created in the image and likeness of Jesus, and is now a new creation. Ergo, the metaphysical substance has changed. Truly, wholly, entirely, and substantially. And this is all we believe when it comes to the nature of the Lord's Supper (the Eucharist)."The bread and wine do not turn into the literal body and blood of Christ.
Catholics oftern say thier view is supported by Luke 22: 19,20, where Jesus told the disciples that the bread and wine are His body and blood.
BUT notice that Jesus was 'physically present' with them when He said this. OBVIOUSLY He intended His words to be taken figuratively.
