As freeper AlaninSA noted to another poster, all the churches that separated from Rome, did so out of ego.
the first churches held that they were carrying on the true traditions of the church universal that had been corrupted by Rome.
Churches? - According to Scripture, Christ wanted us to be one (John 17:22-23). We are all as a Church to be of one mind and to think the same (Philippians 2:2; Romans 15:5). There is only to be one "faith" (Ephesians 4:3-6), not many. For the Church is Christ's Body and Christ only had one Body, not many. Also, since the Church is Christ's Bride (Ephesians 5:29), can Christ be married to more than one wife (essentially a spiritual form of the the sin of polygamy)? No, Christ can only have one wife (i.e., one Church, not many).
Corrrupted by Rome? Such as what? Please back up your accusations with facts.
