The Church is the Apostolic Church. Full Stop. If you're not a member of the Apostolic Church (which includes the Assyrian, the Oriental, the orthodox and the Catholic churchs), then you are in imperfect communion with the Church -- at the very least, at worst you are a non-Christian (to which I'd put in non-Trinitarians)
***The Church is the Apostolic Church.***
Wrong.
The Church is Christ and those who believe. PERIOD.
