Why do you never mention the Eastern Orthodox Church? After all, when it comes to doctrines of the the Creator of the Flat and Immovable Earth, there is no real distance between Orthodoxy and Catholicism. They spring from the same "rotten" root of Constantinian/Imperial/Nicene dogmatism, do they not? At the heart of both is the rejection of Arianism and Docetism and firm affirmation of both homoousios and Trinitarianism. The doctrinal separation between them came much, much later and didn't really touch on these points directly. Nevertheless, in the Orthodox tradition clerical celibacy was never the same kind of issue as it became with the Roman rite in the 11th and 12th centuries.
