Like Muslims, they must falsely try to make every believer into one of them, even though they definitely were not. The church of Rome is such a deformation of the NT church that it is basically invisible in Scripture.
Sorry if you took my comments pro or con for the Roman Catholic Church. I have no great love nor angst for the institution, but do love many of the folks that attend there.
My thoughts were about the powerful!, powerful! Words of the Book. A love of the comfort, the power and joy that flows from Genesis 1:1 to Revelation 22:21 building upon each so that none can be lifted out on its own without tearing the fabric of the whole.
God’s Words need no walls, only hearts to abide in. :-)
As for claims of original institute... again, you have the Word as your guide... not man :-)
