Diocese of Baguio
The Diocese of Baguio is a Latin Church of the Catholic Church in the Philippines comprising the city of Baguio and the province of Benguet on Luzon island in the Philippines. Its see is the Our Lady of Atonement Cathedral.
It was erected to a diocese in 2004 as a suffragan of the Archdiocese of Nueva Segovia. It is currently headed by the Most Rev. Rafael T. Cruz, the third Bishop of Baguio, succeeding Victor Barnuevo Bendico, who was appointed Archbishop of Capiz.
History
The diocese is one of the oldest ecclesiastical territories in the Philippines. It was established as the Apostolic Prefecture of Mountain Provinces on July 15, 1932. The territory that the Diocese of Baguio now spans was split from the Archdiocese of Nueva Segovia.On June 10, 1948, the apostolic prefecture was elevated to the Apostolic Vicariate of Mountain Provinces, entitling it to a titular bishop. The apostolic vicariate received a papal visit from John Paul II in February 1981.
On July 26, 1992, the apostolic vicariate was renamed the Apostolic Vicariate of Baguio, after ceding territories to form the Apostolic Vicariate of Bontoc-Lagawe and the Apostolic Vicariate of Tabuk.
On June 24, 2004, the apostolic vicariate was elevated into the Diocese of Baguio, losing its missionary pre-diocesan status and becoming a suffragan of Archdiocese of Nueva Segovia.
On June 20, 2024, Rafael Tambao-An Cruz was announced as the next bishop, replacing then Bishop Victor Barnuevo Bendico, who was elevated as Archbishop of Capiz in May 2023. He was ordained on September 7 at Dagupan Cathedral by Archbishop Socrates Villegas of Lingayen-Dagupan as principal consecrator, with Archbishop Victor Barnuevo Bendico of Capiz and Bishop Jesse Mercado of Parañaque as co-consecrators. His installation took place on September 17, 2024, led by Archbishop Charles John Brown and Jose Cardinal Advincula of Manila at the Baguio Cathedral.
