I don't believe there has always been an assembly of Christians that believe salvation as expressed by the UPCI-- which is one of many reasons why what they say doesn't hold water with me any more.
None of the other revivals that happened before Azusa brought about the UPCI doctrine-- were those not real revivals? Was God just prepping those saints for the revelation to come? Ok-- what if they died before that
Acts 2:38 revelation as presented by the UPCI?
To think that NO ONE will go to heaven unless they are baptized "in the Name of Jesus" and speak in tongues CONDEMNS the vast majority of anyone who ever expressed faith in Jesus Christ.
AND... Paul and Silas didn't insist that the jailer speak in tongues. They insisted the jailer believe.
Salvation as presented by the UPCI has so many holes!
To be honest, I don't even know why I try to hold on to any thing that ties me to those people or their stupid doctrines. All it does is create confusion and strife as they attempt to fill in holes where the Bible is silent when if they really believed what the Bible says, there wouldn't be any holes in their doctrines concerning salvation.
