The Life

Gonzalo Alonso Calzada Guerrero was born on 7 July 1964, was ordained a priest on 18 May 1989 for the diocese of Celaya, was appointed auxiliary bishop of Antequera, Oaxaca, with the titular see of Cissa, on 20 November 2012, and was consecrated bishop on 5 February 2013, so the auxiliary tenure codes from consecration. On 20 October 2018 he was appointed Bishop of Tehuacán, and he was installed and took possession of Tehuacán on 4 December 2018, roster-exact, so the auxiliary tenure closes at the 20 October 2018 appointment under the auxiliary-close rule and the Tehuacán tenure opens at that possession. He was still Bishop of Tehuacán at as_of: he turned 62 on 7 July 2026, and no resignation acceptance, successor, or transfer news surfaced. He is diocesan clergy of Celaya; he has no religious congregation and no post-nominal initials. His Tehuacán predecessor Rodrigo Aguilar Martínez served 2006-2017, so the see was vacant roughly eleven and a half months, November 2017 to December 2018, before his installation.

On the morning of 23 July 2024, en route to a community to celebrate its patron saint's feast day, he was assaulted on a highway and his vehicle and personal belongings were stolen; the Diocese of Tehuacán's statement of 24 July said he was unharmed and had filed the related complaint. That is victimhood, bio prose only, never a controversy; the diocese's statement lines are the diocese's words, never his quotations, and a further detail about the assault that the article itself flags as not commented on by the diocese is omitted, never reported as fact. In the CEM he is listed in the Prot. 314/24 comunicado for the triennium 2024-2027 as Responsable of the Diocesan Team for Biblical Animation in the Episcopal Commission for Prophetic Pastoral Care, checked-and-LISTED, background only, never a tenure and never a Traditionis custodes act.

A Wikipedia-tier claim that he was Celaya diocese seminary rector at his appointment is recorded as a lead in the reference notes, not asserted here, and the ordinary of Antequera during his auxiliary years is not established in any opened source, so no name is asserted for it.

In His Own Words
care for their children, be close to them and talk to them: that's the way they can help them find the path. ... Before God, [parents] will have to give an account of what they have done for their children,

The Old Mass, See by See
Tehuacán2018-12-04 – presentNo act of his own
What he inheritedOpen tenure falling entirely inside the Traditionis custodes window; no governing act of his own concerning the 1962 Missal was found for it through as_of, and no statement of his concerning communion with the Society of St. Pius X after the Holy See's 2 July 2026 schism declaration was found. WEAKEST LINK: the possession rests on Catholic-Hierarchy alone at spine tier; three search rounds for a diocesan-primary possession report returned only pollution, so the date is NOT upgraded on spine alone (Pozos precedent). His predecessor Rodrigo Aguilar Martinez left in November 2017, before the TC window, so there are no predecessor TC acts to inherit, and no CEM collective act is attributed to him.
Since the SSPX decree of 2 July 2026: No statement recorded as of 2026-10-28.

Mexican bishop assaulted and robbed on highway, 27 July 2024 — CNA/ACI Prensa (via the fullycatholic.com mirror) · 2024PRESS, QUOTE SOURCE, WITH TWO CAVEATS. Byline ACI Prensa Staff, CNA; the mirror reproduces the CNA text with byline and the footer 'translated and adapted by CNA,' and the publisher of record (ACI Prensa/CNA) is named, so the mirror is an acceptable access link per the citation standard; the CNA original itself was not opened, recorded here. ENGLISH-RENDERING CAVEAT REQUIRED: CNA translation/adaptation of ACI Prensa. Setting: two days after the robbery, at a Mass at St. James the Apostle parish in Caltepec. Shipped entry: 2 fragments, 39 words, parent-recounted (Fragment B 22 words; Fragment C 17 words, with the bracketed [parents] as the article's interpolation, not his word). NEVER SHIP: the full 51-word sentence (over cap); the 16-word sub-fragment together with the shipped entry (39 + 16 = 55); the diocese's statement lines ('was unharmed and has filed the related complaint' and the prayers for peace and for the assailants), which are the diocese's words, never his; or the further assault detail the article flags as not commented on by the diocese.
