Complete garbage. The King James Bible has in it exactly what God wants to have in it. Not only is the Church ordained by God but it is itself a mystery that is part of that unknowable plan that God has for how we will ultimately relate to him in heaven.
Well you can start with Revelation 1.
Revelation 18-22 states that the Church is the bride of Christ, obviously something that we cannot fully understand. But it seems to mean that the Holy Trinity will be changed in some way as now the Church seems to be part of God's final plan in heaven.
