Tendentious, anti-Catholic, biased ... oh, and incorrect.
Nothing about geocentrism was ever dogmatised. I don't know how trustworthy the rest of the piece is, but if it's bad as this passage, it's worthless.
Your instincts were correct. The entire thing is an elaboration of the false premise that Ptolemy and Aristotle were proclaimed as Church doctrine.
I wish some of these folks would take the time to do a bit more careful research. The real history is quite a bit more interesting than the junk that attempts to distort it.
Or is good enough just to say, "incorrect" if you are Roman Catholic? It seems the proof you might require for this author you do not require for your Church's regarding its doctrine.
My point, however, was to emphasize the last sentence, not to bash Roman Catholicism. If I cannot do one without the other, then "oh-well".
