The trend is that most Christians in the world living in Africa by 2060
I would say that being narrowly culturally focused least true of Biblical Christianity, more strongly true of Islam and Judaism Most religions locus of belief remains close to it's origins and some like Islam even carry forward the original language
Christianity has moved around. Most Christians in the missile east, then the medeteraniean coastal places, then Europe but spread out, then the Americas now most christians may be in the Global South and China
From Mark Knoll:
- This past Sunday it is possible that more Christian believers attended church in China than in all of so-called “Christian Europe.” Yet in 1970 there were no legally functioning churches in all of China; only in 1971 did the communist regime allow for one Protestant and one Roman Catholic Church to hold public worship services, and this was mostly a concession to visiting Europeans and African students from Tanzania and Zambia.
- This past Sunday more Anglicans attended church in each of Kenya, South Africa, Tanzania, and Uganda than did Anglicans in Britain and Canada and Episcopalians in the United States combined—and the number of Anglicans in church in Nigeria was several times the number in those other African countries.
- This past Sunday more Presbyterians were at church in Ghana than in Scotland, and more were in congregations of the Uniting Presbyterian Church of Southern Africa than in the United States.
- This past Sunday the churches with the largest attendance in England and France had mostly black congregations. About half of the churchgoers in London were African or African-Caribbean. Today, the largest Christian congregation in Europe is in Kiev, and it is pastored by a Nigerian of Pentecostal background.
- This past week in Great Britain, at least fifteen thousand Christian foreign missionaries were hard at work evangelizing the locals. Most of these missionaries are from Africa and Asia.
