Yes, and I still have them. I think if I’d been living in a place where I could have attended the Orthodox church I’d have converted to it instead of becoming Catholic. My personal favorite for an orthodox perspective is Orthodoxy and Heterodoxy by Fr Andrew Stephen Damick. He also has a blog and a podcase. I can’t help with Catholic sources because none of the ones I’ve read have satisfactorily resolved my issues. They all just seem to say the same things.
oh one more book
The First Seven Ecumenical Councils (325-787): Their History and Theology by Leo D. Davis SJ who is a Catholic. Forgot about that one. But it tended to send me even more to the Orthodox side.
