Jeonju diocese belongs to the ecclesiastical province of Kwangju which comprises Kwangju archdiocese and Cheju diocese.
It is the first diocese in the Korean Church to be managed by native clergy since its inception.
Jeonju Catholics take great pride in the fact that in 1931, before being established as a prefecture, it was made an Episcopal vicariate by the bishop of what would become Daegu archdiocese, then under the pastoral care of the Paris Foreign Mission Society. Jeonju diocese was totally under the control of Korean priests, who could implement personnel management independently.
