Again, I will invite you to become familiar with the phjilosophical terms property and substance used by the Church before really engaging in another one of these gotcha games in which the teachings of the church are grossly misstated as the premise of an absurd proposition.
The Church teaches that the Eucharist is "substantially" the body and blood in a very literal sense.
Yea, they use the word transubstantiation which is derived from the Latin trans or across and substantia or substance. In other words they believe that the bread and wine are changed in substance into the literal flesh and blood of Christ. So Catholics must believe that they are literally eating the flesh and drinking the blood of Christ. And I am quite familiar with the philosophical terms property and substance used by the RCC.
It was adopted by the 4th Lateran Council (A.D. 1215), formalized at the Council of Trent (A.D. 1545-63), and was reaffirmed at the Second Vatican Council (1962-65).
The concept of literally eating Christs flesh and blood is pagan materialistic methodology which God condemned often.
