The Church Age is now past as John is instructed to continue his letter with the final instruction to “write those things that will be”.  After spending time in the 2000 year history of the Church and over 19 times that John uses that description, we will not hear “Church” again until the finale of Revelation as the Church is given its’ new name… Bride!
There is one church still remaining that Jesus said would be thrown into the Tribulation and now called, “The Harlot”… The World Church!
