The bulk of West Indians who came to Britain in the 1950s and 60s were Anglicans, Baptists, Methodists, and Catholics, members of the established church in the West Indies. Those who weren't were Pentecostals and belonged to the network of Independent Churches in the West Indies. The experiences of these early Christians weren’t good for when many of them went to worship at their local churches, they were largely ignored, made to feel uncomfortable and some were even told not to come back as their presence was upsetting the white congregations!
Pentecostal Christians had an all together different experience. Rather than going to their local churches to worship, they sort out other Pentecostals and started to hold 'Prayer Meetings' and later, 'Sunday Services' in each other's homes. These meetings were largely held in secret so as not to attract any attention and when they became too large, they rented premises to hold their meetings and when that too proved insufficient they ended up buying their own places of worship.
