What of the 35,000 sects of Protestantism are you referring to? Many have withered and died as did their followers in Jim Jones and David Koresh.
Didn't you get the Memo?
It's up to 50,000 or 80,000 or some such by now!
I see what you mean...
Ephesus,
Smyrna,
Pergamon,
Thyatira,
Sardis,
Philadelphia
and Laodicea.
There are the Protestants, Catholics, the Orthodox and all their various sects, congregations, and their traditions...and there is the real Church of Jesus...drawn and separated from the tares found from all the aforementioned traditions of the Christian faith. The real Christians worship God in spirit and in truth...(no matter what “sect” they might come from) and Christ’s real church, his real Bride consists of such folk!
When Christ rules out of Jerusalem, it won’t be from a Catholic perspective, there will be no religious sectarian splits. His saints will have come from all tribes and tongues and from all former religious sects and creeds. We will all be one in him and He in us!
