By the way there is only ONE church and there can always only be ONE church. But this church is not represented by ANY one denomination, even those like the RCC that falsely claim to be THE church. They too have far too many error, to make such a claim.
Just the fact that somebody formed a group and called it something, takes then outside the true church.
The true church has always walked outside denominations. It started in the time of Paul already, that denominations started to form:
1Co 1:12 Now this I mean, that each one of you saith, I am of Paul; and I of Apollos: and I of Cephas; and I of Christ.
1Co 1:13 Is Christ divided? (denominations) was Paul crucified for you? or were ye baptized into the name of Paul?
So here we can see that they started dividing into denominations (the "Paulists" and the "Apolloists" and the "Cephasts") and Paul was rebuking them for it. But we went that way anyway.
