I know the "Orthodox" schismatics have a bastardization of the Western Rite. I am curious if anyone knows anything in their Lex Orandi that can serve as a refutation of their religion. So far I found two things that could possibly serve as a refutation. The first thing I found that could possibly refute them is the fact they use Lauda Sion on Corpus Christi. This sequence teaches Christ is present whole and entire under both Species contrary to what most Eastern Orthodox hold. This one is a minor refutation but the next one seems like it does more damage. I was reading a pdf from the Western Orthodox that talks about how some Western Rite "parishes" substitute the Athanasian Creed implying it is used in some of their "churches" the Athanasian Creed says the following: "The Holy Ghost is of the Father and of the Son; neither made, nor created, nor begotten; but proceeding." Most Orthodox would call the statement heresy yet they seem to use it in their Western Rite.
