Theology and Doctrine: Explorations of Classical Pentecostal identity, pneumatology, and specific practices such as the use of the veil, the holy kiss, and baptismal rites. Sociology and Culture: Research on the "invisible" nature of the CCB in the public sphere, gender roles in leadership and worship, and the sect's interactions with urban and rural environments. Musicology: A significant corpus of work dedicated to the CCB’s unique orchestral tradition, organist training, and the evolution of its sacred hymnals.
