Channeling is a demonic practice used to conjure up demons to give information during a session.
This practice started in the 1920's and 30's with Judge Rutherford and perhaps continues on until today.
Most of the literature is or was channneled through "automatic writing" sessions.
God's channel is a subliminal message used to denote the fact that "a" god is using them to give them information.
Nothing can be confirmed or verified in this post.
The true Church was on the contrary established on Pentecost 33 AD and is guided by the Holy Spirit. It has never faded or died out to apostacy.
It lives even today.
