You know, the Bible predicts in Revelations 17 that there will be a one-world church (in the last days). I used to wonder how in the world that would ever happen, when everybody’s got their own theology. But there’s something happening today that for the first time in history is just tearing across all the denominational lines. 30,000 Catholics are now at least involved in the inner workings of the charismatic movement. Eight to 14 million people are involved in this right here.Pentecostalism was estimated to number around 115 million followers worldwide in 2000; lower estimates place the figure near to 22 million (eg. Cambridge Encyclopedia), while the highest estimates apparently place the figure between 400 and 600 million. According to a Spring 1998 article in Christian History, there are about 11,000 different Pentecostal or charismatic denominations worldwide.
It’s crossing all the denominational lines. People are getting together sans doctrine, you know. It doesn’t matter what your doctrine is as long as you have this. It could well be that this could be that which could be the catalyst to bring the ecumenical movement that results in the false church in Revelations.
