But it was the Maryknoll Fathers who finally arrived in the area in 1958 and settled down to the arduous task of evangelizing the inhabitants.

The early missionaries later settled in places like Caraga, Baganga, Cateel and the nearby areas, baptizing, giving the sacraments, building churches and convents.

Ecclesiastically, the entire Mindanao area was under the Diocese of Cebu since 1595, until some parts were placed under the jurisdiction of Jaro in 1865.

Meanwhile, the Diocese of Davao had become an archdiocese, and Tagum and Mati were made its suffragans.

For more than 3 years, the diocese was sede vacante until Pope Francis has appointed Abel Apigo as its new bishop on February 10, 2018.
