WI the hierarchy of the Catholic and Orthodox Churches was never established up to the Patriarch or Pope level, with autonomous denominations that may have priests or pastors or preachers, and Bishops or elders at higher levels being the top level? Trinitarian doctrines, communion and much basic doctrine of OTL's Protestant denominations could well be the most dominant (this is not an Arianism or Unitarianism wank) but no denomination can have a credible international claim to be a Catholic or Orthodox Church.
