I have collected some links about Eastern Orthodox theology:
a) The Filioque controversy and its implications. A very good technical text that helped me a lot to understand it. The full book from Laurent A Cleenwerck can be bought here.
(I may be wrong but I think Laurent was my teacher of an online greek course I took in New York!)
b) Perry C Robinson in his Energetic Procession blog on Orthodoxy explains why he chose Orthodoxy over Catholicism basing himself on systematic theology. I found it very interesting, and gave me food for thought. He has other interesting posts like this on Diothelitism.
c) Orthodox Teaching on Personal Salvation. A comprehensive text, and possibly a good review. The few introductory paragraphs maybe have a more negative view of the person that I think I found in other orthodox documents, though.
Testimonials that choose Eastern Orthodoxy rather/or than Roman Catholicism:
a) Robertbar finds the Catholic Church too medieval, with the papacy and the dogma of transubstantiation ad odds with the Early Church. He considers the Novus Ordo Mass an innovative major break in the Church liturgy, and worries that the Catholic Church is going too liberal.
b) Michael Whelton explains how he doesn't like liturgy innovations and the papacy.
c) Nick explains why he is Catholic and not Orthodox. Ordodox don't agree of whether Catholic have valid holy orders or other sacraments. Some EO would even re-baptise a Catholic. He also find suspicious that Orthodoxy didn't manage to have an ecumenical council in a 1000 years.
