Page "Ethnic groups in Bosnia and Herzegovina" Paragraph 9

South Slavs were Christianized in 9th century.

Until the Ottoman conquest of Bosnia, there is evidence of three Christian denominations in Bosnia: Eastern Orthodox, Roman Catholic and an indigenous church known as the Bosnian Church.

Some scholars believe it was a dualist church related to the Bogomils of Bulgaria, while others dispute this claim, citing lack of historical evidence.

Both Orthodox and Roman Catholic officials declared this church to be a heresy.

Apart from testimonies of inquisitors and a few excerpts from allegedly apocryphal texts, we have very little knowledge of the Bosnian Church.

Its connection with Bogomils is spurious, however.

Discussion about how numerous each of these denominations was is impossible with the amount of historical documents presently available.
