The man who wrote the letter is an idiot.
Example:
“The church’s role as arbiter of so-called scientific thought...”
And where did Pope Francis claim that?
Another example:
“The assertion from a pope that God is neither divine nor omnipotent is startling.”
Again, where did Pope Francis claim that? No where EVER. If the idiot author were to respond with, “But, but, but, the pope said “we run the risk of imagining God was a magician, with a magic wand able to do everything. But that is not so” then I would know the author doesn’t understand that God can’t do anything logically contradictory. God cannot make Himself cease to exist, for instance.
And that's what your common sense tells you, eh???
