Orthodoxy is just statist eastern Catholicism. There is never any such concept in the New Testament.

Orthodoxy practices Mariolotry (yes, it does), false sacerdotal hierarchy, prayer to saints and angels, and a host of other falls Christian superstitious quakery just like Roman Catholicism. Both are just two Horns of the same beast.

About the only thing Orthodoxy gets right (which isn't much) is baptism by immersion.
