In the 1980s and/or 1990s Rick Joyner was associated with a controversial Kansas City church movement tied to Mike Bickle, Bob Jones and Paul Cain. He and others were making all kinds of prophecies some of which were related to their new eschatology and false teachings on church government. His prophecy collapsed after the church collapsed.
The Kansas City Metro Vineyard published a newsletter in the early 90s which promoted their church as a model of the newly emerging church. This church had been closely associated with the signs and wonders movement of John Wimber and officially was absorbed into the Vineyard until Wimber discovered how crooked it was. KC “Prophet” Rick Joyner prophesied:
Single presbyteries will form over cities and localities. These will be made up of pastors and leaders from all backgrounds. Their unity and harmony in purpose, as well as that of the various congregations, will become a marvel to the world. . . .
Some leaders will actually disband their organizations as they realize they are no longer relevant to what God is doing. Others will leave them behind to disband by themselves. Ultimately, all circles of ministry or influence with individual identities will dissolve into a single identity of simply being Christian for all who become part of this harvest.
Update: original source
This was a ridiculous prophecy and unsurprisingly it failed. The disturbing thing, however, is it was believed by the Kansas City Prophets and the people who followed them. They actually tried to shut down churches in Kansas City and some closed. They would prophesy that God was telling pastors to close their churches and join their church.
One pastor, Ernie Gruen, was so outraged he took a public stand against them, preaching against their corruption. His activism led to the KCP church getting shut down.
The presbytery prophecy failed for the model church in their ‘model city,’ and it has never been accepted as sound doctrine, either. Until it gains credibility (don’t hold your breath), it is unlikely this prophecy will ever be fulfilled. It is a very tough sell. Joyner himself doesn’t spend a lot of time promoting it, so the conclusion is he now agrees he made a false prophecy.
