First, I don’t refer to anyone as ‘ignorant masses’; that is degrading. Second, we are taught the Eucharists retains all elements of bread and wine. It is a matter of faith that Jesus is present as he promised.
Meanwhile, some Fundamentalist do go against the science of a young earth. The Eucharist does not go against scientific reality. Young Earth does, despite science, despite passages in the Old Testament where a ‘day’ is used as a long period time, not just 24 hours. If you were to say, “In my grandfather’s day…” do you really expect people to conclude your grandfather lived only one day?
Catholics, for centuries, have left science to scientists and stick with teaching faith, and that has worked well.
