True.
From what I've read will say that it should be pretty clear to all that 'Orthodox' churches haven't tended to go as nutty as the Roman Catholic church got, through the last millenium.
I think the writers of the Epistles and Jesus Himself had some things to say about avoiding gnostic/dualistic influences and about unadorned spiritual reality vs. trappings and rituals, that I think any high church could heed.
Any low church, too.
