“The earliest known use of the term “transubstantiation” to describe the change from bread and wine to body and blood of Christ in the Eucharist was by Hildebert de Lavardin, Archbishop of Tours, in the 11th century.[13][14] By the end of the 12th century the term was in widespread use.[15] The Fourth Council of the Lateran, which convened beginning November 11, 1215, spoke of the bread and wine as “transubstantiated” into the body and blood of Christ: “His body and blood are truly contained in the sacrament of the altar under the forms of bread and wine, the bread and wine having been transubstantiated, by God’s power, into his body and blood”.[17]”
And after 1300 years of “development”, that belief is read back into the Scriptures as if it originated there... And is sworn to as always being held.
Yep! That’s how they do it. Now you would think all these brilliant theologians would figure this out before they swim that polluted river Tiber.
