Another Seminary Introducing the Usus Antiquior into Seminary Liturgical Life
Recently it was reported on the NLM that Holy Apostles Seminary has introduced a weekly Mass in accordance with the usus antiquior.
In addition to that seminary, Kenrick Seminary in the Archdiocese of St. Louis is also offering Holy Mass in Latin weekly, alternating between the Missal of Pope Paul VI and the Missal of Blessed John XXIII. (Mass is also celebrated in Spanish weekly to prepare the seminarians to meet the needs of the growing number of Hispanic faithful.) In light of the recent Motu Proprio, the seminary desided to expand the its use of liturgical Latin and to integrate the classical liturgy in the liturgical life of the seminary.
A part of the philosophy behind this is quite pragmatic: just as in the case of the growing need for American parish priests to have the ability to celebrate the Mass in Spanish, so too will there be a greater need to have the ability to celebrate the Mass in Latin, both in the Pauline missal and in the usus antiquior. But in order for this to most effectively happen, the seminarians need to receive some exposure in the seminary to this.
