Mario Alberto Avilés
Mario Alberto Avilés was born September 16, 1969, in Mexico City, the son of Rafael and María Guadalupe Avilés. In 1986, at sixteen, he entered the Congregation of the Oratory of Saint Philip Neri (the Oratorians), whose members carry the post-nominal 'C.O.' He studied at the Universidad Panamericana in Mexico City and the Pontifical Athenaeum Regina Apostolorum in Rome, later earning a Master of Divinity from Holy Apostles College and Seminary in Connecticut and a master's in education administration. He was ordained a priest on July 21, 1998, at the Basilica of Our Lady of San Juan del Valle in San Juan, Texas.
Avilés spent nearly two decades in parish and educational ministry in the Rio Grande Valley of the Diocese of Brownsville — as pastor of Sacred Heart Parish in Hidalgo (2002–2017) and, from 2005, as director of the Oratory Academy of St. Philip Neri and the Oratory Athenaeum for University Prep in Pharr. Education is the thread running through his career; he has called it his 'passion.' Within his order he served as procurator general of the Confederation of the Oratory (2012–2018). On December 4, 2017, Pope Francis appointed him the first auxiliary bishop of Brownsville; he was consecrated February 22, 2018.
On December 1, 2025, Pope Leo XIV accepted the resignation of Bishop W. Michael Mulvey and named Avilés the ninth Bishop of Corpus Christi; he was installed January 28, 2026, the first Hispanic bishop to lead the diocese in roughly three decades. His public profile centers on Hispanic ministry, Catholic schools, and advocacy for migrants along the Texas–Mexico border. As of mid-2026 he is the sitting diocesan bishop, not merely an administrator.
An honest assessment must begin with a caveat: Bishop Avilés was installed in Corpus Christi only in January 2026, and no public record has yet surfaced of him personally celebrating, authorizing, restricting, or even commenting on the Traditional Latin Mass. He is an Oratorian and a career educator whose stated priorities are catechesis, Catholic schools, Hispanic ministry, and migrants. On the traditional liturgy specifically, his record is close to blank, and we will not manufacture a verdict where the evidence does not exist.
The diocese he inherits, however, is already hostile terrain for the old rite. His predecessor, Bishop W. Michael Mulvey, suspended the only diocesan-approved Traditional Latin Mass — the St. Michael the Archangel Latin Mass Community, latterly meeting at St. James parish in Refugio — by decree in April 2023, citing the loss of its priest. There is no FSSP, ICKSP, or other traditional apostolate in the Diocese of Corpus Christi. In practical terms, a Catholic there today has no public access to the traditional Mass, and restoring it would require an affirmative decision by Avilés under the restrictive regime of Traditionis Custodes.
One faint, indirect signal cuts slightly favorable: Avilés spent his priesthood and his auxiliary years in the neighboring Diocese of Brownsville, where Bishop Daniel Flores took a comparatively tolerant line under Traditionis Custodes, keeping two parishes' 1962-Missal Masses in place. Avilés served in that environment without any recorded objection — though there is no evidence he championed the old rite either. The verdict is therefore a suspended judgment: no friend and no enemy on the present record, governing a diocese where the traditional Mass has already been extinguished and where the burden — and the opportunity — of its restoration now rests entirely with him. Traditional Catholics should watch his first liturgical decisions closely.
