I recently gave a 90-minute presentation on the similarities and
differences between Roman Catholicism and Eastern Orthodoxy for an Institute
class for my district followed by a rather lively 30-min Q&A. While I do
not consider myself as informed as I wish I was about Eastern Orthodoxy, I
think it is fair to say that I am well-read on Roman Catholicism on many issues
(Papacy; Christology; Mariology; Mass, etc). I have put the slides I used
online here. While some may only make sense if one was at the lesson itself, I
do hope it adds some food for thought.
