There are denominations, better and worse. There are non-denominationalists, better and worse. All groups are likely to have unsaved people playing church who never really trusted Christ as Savior. The teaching to accept is
Believe on the Lord Jesus Christ and you shall be saved. You must trust Him as Savior, not as an opportunity giver.
The Universal Church of whole the NT now is explained.
There are no monks and hermits inside, but as rightly noticed someone above devils are also members of the church, since they also believe that Jesus is the Lord.
There are no monks or hermits in the Bible, and no rocket scientists either. But monks and hermits can be saved if they trust Jesus as Savior instead of works. I think that there may saved monks, maybe also hermits -- if saved, then they are in the Universal Church. Those orthodox and RCCists who trust Christ as Savior are also in the same Church I am a member, the Body of Christ.
So you want me tortured by an inquisition, Hobo?
I want only good for you.
Why not ask the Lord Jesus to save you? Can't you trust Him to get you to Heaven?
