A belief that priests serve as intermediaries between God and people, emphasizing their important role in religious practices.
The church's teachings were heavily influenced by sacerdotalism, which placed great importance on the role of priests.
Sacerdotalism is formed from "sacerdos" (meaning priest) and "-al" (meaning relating to) combined with "-ism" (meaning a doctrine or belief). The term refers to the belief in the priestly role and the importance of priests in religious practices.
