Protestants look back longingly to the Reformation as one of the great periods of church history, and it was in many respects. In terms of the global reach of Christianity, though, the sixteenth century was a low point. Since its beginning, Christianity has rarely been confined to so contracted an area.
In the fourth century, Christianity encircled the Mediterranean. It was still strong in Palestine, in the Middle East, and further east. Jerusalem was a largely Christian city for many centuries. Christianity was dominant in North Africa, from Egypt to Carthage and beyond. It was taking hold in Northern Europe. Christian missionaries were being exported from Ireland, the out-back of Europe.
Islam pushed Christianity into Europe, and during the second half of the fifteenth, it “became increasingly a European religion. Islam had launched a jihad against Christianity several centuries earlier.

The numbers are staggering: “According to the respected World Christian Encyclopedia, some 2 billion Christians are alive today, about one-third of the planetary total. The largest single bloc, some 560 million people, is still found in
Pentecostalism in particular has risen from literal non-existence to become one of the largest groups of Christians in the world: “Since there were only a handful of Pentecostals in 1900, and several hundred million today, is it not reasonable to identify this as perhaps the most successful social movement of the past century? According to current projections, the number of Pentecostal believers should surpass the one billion mark before 2050.

And that is just talking of the of the diverse currents of rising Christianity: there will be even more Catholics than Pentecostals” (8).
