The official teaching of the Catholic church is that the consecrated communion wafer IS the flesh and blood of Jesus.
(From the Baltimore Catechism)
"The Holy Eucharist is a sacrament and a sacrifice. In the Holy Eucharist, under the appearances of bread and wine, the Lord Christ is contained, offered, and received.
(a) The whole Christ is really, truly, and substantially present in the Holy Eucharist. "
By EVERY POSSIBLE test, there is NO WAY to prove that the bread IS NOT still bread.
So, obviously, you guys & gals DO NOT BELIEVE the Catholics' untestable claim.
And yet, by EVERY POSSIBLE test, there is NO WAY to prove that YOUR Goddesses and Gods exist outside of the human imagination, yet you scold us atheists because we DO NOT BELIEVE your untestable claims.
