The new papal document also details the responsibilities of bishops whose dioceses already have one or more groups offering the Traditional Latin Mass. It mandates that bishops determine these groups do not deny the validity of Vatican II and the Magisterium.
Bishop Paprocki determined that several such groups operating in his diocese fulfill these requirements. The groups include the Canons Regular of the Society of Saint John Cantius, the Priestly Fraternity of Saint Peter, and the Canons Regular of Saint Thomas Aquinas.
The Canons Regular of St. John Cantius, a community of priests based in Chicago, have offered both forms of the Roman Rite since their founding, the group said in a July 16 statement.
“We believe we are in a unique position to show the unity and diversity of the liturgical heritage of the Church. We were founded to offer the gifts and treasures of Holy Mother Church for the sanctification of all, in communion with the Magisterium, and ‘in union with the local ordinary and his diocesan mission,’” the group wrote, adding that they look forward to working with their local ordinary, Cardinal Blase Cupich, on the implementation of the motu proprio.
“We remain focused on our mission of Restoring the Sacred and will continue our work in our parishes,” the Canons concluded.
The motu proprio instructs bishops to verify that already-established parishes with traditional liturgies “are effective for their spiritual growth and to determine whether or not to retain them.” Paprocki declared Saint Rose of Lima to be “effective for the spiritual growth of the faithful.
The FSSP, which celebrates the Traditional Latin Mass, addressed the motu proprio in a July 16 statement.
"At this point, it is too early to tell what all the implications will be for the Priestly Fraternity of St. Peter, but we assure you that we remain committed to serving the faithful attending our apostolates in accordance with our Constitutions and charism as we have done since our founding," the order said in a statement provided to CNA.
"We must strive to see this Cross as a means of our sanctification, and to remember that God will never abandon His Church."
Since the document’s release, some bishops have said that they will simply allow the Traditional Latin Mass to continue as scheduled in their dioceses, or that they will make a decision later about how to implement the motu proprio.
