The Roman Church which is the great harlot of religious Rome that makes drunk the nations with the wine of the wrath of her fornications (Rev. 14.8) claims to be the one true church and if you are not a member of, you are not saved and shall go to Hell.

The Roman Church claims to be the true church solely based on pedigree, but don't many cults use the same reasoning. Since the Bible nowhere requires pedigree then this is a false argument on their part.

Do not exceed the written word of God. "Do not go beyond what is written" (1 Cor. 4.6).

The true Church, of course, is that Church where 2 or 3 are gathered in His name, or more, who are born-again. Even if they reject biblocality they are still the Church because they are saved members of the body of Christ no matter how disorganized they are.

But it is God's will Christians abide in locality, that is, where Apostles today, directly chosen by God, work regionally to appoint Elders of a locality, and in turn, the Elders of a locality approve the Elders of many meeting places within a locality. The Church is not divided by congregation or denomination, but by locality only! The Church is never defined as a congregation or a denomination. Never forget this!

The Church is the pillar of truth, but that truth is founded on the word of God the 66 books of the Bible.

Paul spoke authoritatively the word of God which was written in his letters, that never exceeded what was formerly written, to complete the word of God in the 66 books.
