The churches of Jesus will exist until He returns, if I understand what Jesus said
Jesus used the singular number when He refered to the specific Church (after all, He did say "
My church" not the "my churches" or "the churches") which He is currently building.
This language is used of the local churches of the Revelation which had been infiltrated by "Jezebel", the "Nicolaitans", etc.
My view is that the Church of Matthew 16 which Jesus is currently building of which the gates of hell shall not prevail consists of all the saints collectively out of all the local churches (saved only) from then until now.
...the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect.
I lived in Maine for 15 years in a town of 500 people.
At one time this town's population was over 20,000 people with local churches that now no longer exist and have been plowed into the ground.
Did the gates of hell prevail against these "churches"?
Not that I diminish the doctrine of the local church and the provision of the gifts of the Spirit to the saved within each, however they are each potentially a mixture of saved and lost and therefore I personally make a distinction between the Church consisting of only the saved over the ages and the local churches of mixed multitude.
I believe this distinction is scriptural (Matthew 16:18, Hebrews 12:23,).
But also, personally, I don't draw out the debate concerning this distinction too far, so for now I am done (unless provoked).
