Church services and religious change in Burundi

In Burundi, weekly services are the primary point of contact between churches and their followers, with most of the population attending. These gatherings provide churches with a strategic platform to attract and retain members. Over six months, we collected data from five churches in the rural town of Muramvya—Catholic, Anglican, Pentecostal, FECABU (Evangelical), and Adventist—analyzing 125 transcripts for structure, themes, scope, tone, and key words. We find that emerging denominations—Pentecostal, FECABU, and Adventist—pursue different strategies than traditional ones. Pentecostal and FECABU churches place greater emphasis on rituals than on scripture readings, adopt a more positive tone, and focus on the immediate concerns of their congregants rather than abstract topics. The Adventist Church, while also emphasizing rituals and using a positive tone, distinguishes itself with a stronger commitment to scripture. The Pentecostal church uniquely combines a focus on morality with references to supernatural punishment. We argue that this blend of approaches among emerging denominations strengthens group cohesion and enriches individual faith experiences, helping them attract followers. Our findings shed light on the growth of these denominations in Burundi and may help explain broader religious trends across Sub-Saharan Africa.
