Most people believe that their religion/denomination is the one true faith. I wonder how religious people explain the fact that their own faith is usually related to their personal background.
In England, about 45% of the population belongs to the Church of England. About 10% are Catholic, and about 9% other Christian denominations (mostly Methodists and Baptists, both native to England). English Catholics comprise recusants (concentrated in the north, especially Lancashire), immigrants/diaspora, and converts (mostly from Anglicanism). Other religions in England are represented almost entirely among ethnic minorities. E.g., one of the largest concentrations of Buddhists is found in Aldershot, due to Nepali soldiers stationed at the garrison, while white British converts make up only about 1.5% of Muslims.
Anglicanism is concentrated in countries/regions with strong ties to Britain: Africa (which accounts for more than half of all Anglicans), the US, Canada, the West Indies, Oceania, the Indian subcontinent, and Hong Kong. There are more than 18 million Anglicans in Nigeria, but only about 320,000 in Latin America. Somebody from Nigeria is about 190 times more likely to be an Anglican than somebody from Latin America is.
Around 40% of all Catholics live in Latin America, which is obviously due to Spanish/Portuguese colonisation. The Philippines, also a former Spanish colony, is the third most populous Catholic country in the world with about 7% of all Catholics. If one looks at the distribution of Catholicism, one sees that it is concentrated in regions of Europe and in former European colonies. One exception is South Korea, which has a large Catholic population, but was never colonised by a European country.
In East Timor, about 97% of the population are Catholic and therefore include the filioque in the Nicene Creed. In Serbia, up to 97% of the population is Eastern Orthodox (estimates vary). The Catholic and Protestant minorities are concentrated in the north of the country, the Muslim minority, in the southwest. Therefore, somebody from Serbia (outside the north or southwest) will almost invariably be Orthodox and will not include the filioque. Therefore, it seems that one’s beliefs about the procession of the Holy Spirit are determined more by geography than by theology.
Almost half of all Muslims live in five countries in Asia and Africa, while there are 10 countries in Asia and Africa where 99%-100% of the population are Muslims. I assume that the vast majority of Muslims believe that Islam is the one true faith, while the vast majority of Christians believe that Islam is a false religion. It seems that whether one is a Christian or a Muslim is largely determined by culture, ethnicity, and nationality, rather than any kind of objective evaluation of competing religious claims.
I assume that most Catholics would say that the Catholic Church is the one true church and that its teachings are objective and absolute. However, people’s religious beliefs are usually determined by factors such as the religious beliefs of their parents and/or the main religion practised in their community or country. How do Catholics explain this?
