Bishop Antonio Tobias offered a Solemn Pontifical Mass in the Cathedral of the Good Shepherd on Easter Monday, April 25, 2011, marking the first time since the liturgical reform that a Filipino bishop offered Mass according to the pre-Conciliar rites in his own cathedral. A post on the event and more pictures can be found in The Pinoy Catholic.
He was assisted by the Franciscan Friars of the Immaculate.
