Why do historians question the claim that the Bosnian church followed Bogomil beliefs?

Historians increasingly question the theory that the Bosnian church followed the dualist beliefs of the Bogomils due to a lack of reliable evidence and significant theological contradictions.12

While 19th-century scholars often linked the two, modern research suggests that papal denunciations—which accused the Bosnian church of Manichaeism—were likely based on limited knowledge of the actual conditions within Bosnia. These external observers may have confused the Bosnian church with genuine dualist heretics present on the Dalmatian coast.2

Furthermore, the religious practices of the Bosnian church directly conflicted with core Bogomil tenets. While Bogomils rejected material aspects of faith, the Bosnian church accepted:
* The Old Testament2
* The sign of the cross2
* The mass and the use of church buildings2
* The consumption of wine2

Consequently, many scholars now view the Bosnian church as a nonheretical branch of the Roman Catholic Church that had become isolated, leading to the adoption of some Eastern Orthodox practices and lax administrative oversight.2
