Archbishop García-Siller denounces family separation in pastoral letter

Archbishop Gustavo García-Siller of San Antonio released a pastoral letter Wednesday urging U.S. Catholics to oppose policies that separate immigrant families or confine them in detention centers. The letter, titled “Welcoming the Stranger in Our Midst,” marks the first major policy statement from a U.S. bishop since Pope Francis renewed calls for compassionate immigration reform in early 2024. García-Siller’s stance comes as the Catholic Church in America reorients its advocacy, moving beyond symbolic statements toward sharper criticism of border enforcement.

The archbishop’s shift reflects a personal and institutional reckoning. Friends and aides say García-Siller’s thinking was shaped by years of listening to grieving families in South Texas who lost loved ones crossing the desert or died in Border Patrol custody. One turning point came in 2019, when he presided over the funeral of Jakelin Caal, a 7-year-old Guatemalan girl who died in Border Patrol care. He later visited migrant shelters and heard children describe hunger, fear, and separation from parents. The new letter draws directly from those encounters, framing immigration enforcement not as a security issue but as a moral failure.

In the letter, García-Siller cites Church teaching on the dignity of the human person and calls for an end to prolonged detention, the use of for-profit prisons, and the separation of children from parents. He also urges Catholics to pressure lawmakers and to support legal pathways for asylum seekers. The document has drawn cautious praise from immigrant advocates and some bipartisan discomfort. A spokesperson for the U.S. Conference of Catholic Bishops said the letter is “under review,” while a senior aide to House Speaker Mike Johnson dismissed it as “out of step with border security needs.”

García-Siller’s letter signals a broader shift within the U.S. Catholic leadership. Since Pope Francis elevated the issue of migration in his 2023 encyclical “Fratelli Tutti,” bishops in border dioceses have grown more vocal. Phoenix Bishop John Stowe and El Paso Bishop Mark Seitz have both issued strong statements in recent months. García-Siller’s pastoral letter could accelerate that momentum, prompting other bishops to act before the 2025 congressional session. For now, the question is whether the letter’s moral clarity can overcome political polarization—or whether it will be another voice in the wilderness.
