Gustavo Garcia-Siller
Gustavo Garcia-Siller was born on December 21, 1956, in San Luis Potosi, Mexico, the eldest of fifteen children of Gustavo Garcia Suarez and Maria Cristina Siller de Garcia. He grew up working in the family furniture store, sweeping floors and washing windows, and in 1973 entered the Missionaries of the Holy Spirit, professing in 1975. His formation took him to St. John's Seminary in Camarillo, California, for degrees in divinity and theology, and to Guadalajara and the Jesuit university in that city for philosophy and psychology.
Ordained a priest on June 22, 1984, in Guadalajara, he had been sent to the United States in 1980 to minister to migrant workers in California, the work that would define him; he became an American citizen on December 15, 1998. Pope John Paul II named him an auxiliary bishop of Chicago in January 2003, and Cardinal Francis George ordained him that March. On October 14, 2010, Benedict XVI appointed him Archbishop of San Antonio, and he was installed on November 23 at St. Mark the Evangelist Church.
In San Antonio he shepherds one of the largest and most heavily Hispanic archdioceses in the country, and has become one of the most publicly outspoken American bishops on immigration and the border, framing migrant welfare as a duty of faith: 'It's business, business, business - and people are suffering, including children. I call it a really perverse, inhumane system.' In March 2024 he suppressed the New Braunfels Mission of Divine Mercy apostolate and removed its priest after the group called Pope Francis a usurper.
- 2021In the wake of Traditionis Custodes the diocesan old Mass was moved out of St. Pius X to the smaller, less central St. Timothy parish, and its Sunday slot pushed from 10 a.m. to 2:30 p.m. (later eased to 12:30 p.m.); baptisms and marriages in the older rite were barred. The Mass itself continues at St. Timothy. The relocation's exact instrument and date are not in the public record in hand, and this action's confidence is set accordingly. ↗
The diocesan Traditional Latin Mass in San Antonio once had a settled home at St. Pius X parish. Under Archbishop García-Siller, in the wake of Pope Francis's Traditionis Custodes (2021), it was moved out — relocated to the smaller, less central St. Timothy parish and pushed into a Sunday afternoon slot. The community that prays the old rite was, in plain terms, displaced and diminished: shifted from a prominent church to an out-of-the-way one, and from the heart of the Lord's Day to its margins.
In fairness, San Antonio has published no harsh decree of the kind Chicago or Detroit produced, and the archdiocese is thin on the public record — and so the sharper reports (a move to a 1:30 p.m. hour, a restriction of the older form of baptism and other sacraments) we have not been able to confirm against a primary diocesan document, and we will not assert what we cannot source. What is documented is a relocation and a downgrading.
That is enough for the verdict the traditional Catholic must render. A shepherd who finds a flock at peace around the ancient Mass and answers it by sending that Mass to a smaller room at a less convenient hour is not, on this question, its friend. We hold the door open to correction if the archdiocese acts otherwise — but on what is known, his record toward the Mass of Ages is one of restriction, not of welcome.
