The Life

Carlos Aguiar Retes was born in Tepic on 9 January 1950, the second of six children of Carlos Aguiar Manjarrez and María Teresa Retes Pérez-Sandi. He studied at the seminary of Tepic, continuing at the seminary of Montezuma in the United States and at Tula, and obtained a licentiate in Sacred Scripture from the Pontifical Biblical Institute and a doctorate in biblical theology from the Pontifical Gregorian University in Rome. He was ordained a priest on 22 April 1973, the date the Vatican biography gives and which governs here; the Wikipedia body date of 23 April 1973 is a variant, flagged, not merged. His offices were parish vicar; rector of the seminary of Tepic and at the same time chairman of the Organization of Mexican Seminaries, OSMEX, and member of the Executive Council of Latin American Seminaries; and rector of the John XXIII residence for priests at the Pontifical University of Mexico and professor of Sacred Scripture in the same university. Wikipedia-tier detail adds: deacon 24 December 1971; Rome 1974-1977, at the Pontifical Latin American College and the Biblical Institute; rector of the Tepic seminary 1978-1991; OSMEX president 1986-1990; member of the Biblia de América team 1992-1993; doctorate 1996; member of the Pontifical Council for Interreligious Dialogue from 8 March 2007; member of the Aparecida drafting committee under Bergoglio, conference background; moderator of the Spanish-language group at the Synod on the New Evangelization in October 2012; Grand Prior of the Mexico Lieutenancy of the Order of the Holy Sepulchre; and cardinal elector at the 2025 conclave.

He was appointed bishop of Texcoco on 28 May 1997 and received episcopal ordination on 29 June 1997; his consecrators are Wikipedia-attributed, not asserted: principal Adolfo Antonio Suárez Rivera, co-consecrators Magín Camerino Torreblanca Reyes and Alfonso Humberto Robles Cota. He was the third bishop of Texcoco by the Wikipedia-tier count, succeeding Torreblanca Reyes (1978-1997). He was appointed metropolitan archbishop of Tlalnepantla on 5 February 2009; the Alchetron date of 3 February 2009 is a variant, rejected. His Tlalnepantla possession on 31 March 2009 is Wikipedia-tier only and is flagged as such; a Catholic-Hierarchy March 2009 events page or a Tlalnepantla archdiocesan installation item would settle it and is still owed. His Tlalnepantla predecessor Ricardo Guízar Díaz rests on Alchetron only and is not asserted. He was nominated archbishop of Mexico on 7 December 2017 and took possession on 5 February 2018, as his own installation message puts it, asumo a partir de hoy, 5 de febrero del 2018, with Wikipedia agreeing, Installed 5 February 2018. He was created cardinal by Pope Francis in the consistory of 19 November 2016, Cardinal-Priest of Santi Fabiano e Venanzio a Villa Fiorelli; the Wikipedia infobox form Santi Fabriano is a typo. He is a member of the Pontifical Commission for Latin America and of the Dicastery for Culture and Education, and took part in both assemblies of the Synod of Bishops on the Family in October 2014 and October 2015. His conference offices, background only, were secretary general of the CEM 2004-2006 and president 2006-2012, and secretary general of CELAM 2000-2003, first vice-president 2003-2007, and president 2011-2015.

His episcopal motto is Que todos sean uno, May all be one, asserted here because it stands in his own words in his installation message: El lema de mi escudo episcopal recoge la oración de Jesús al Padre: Te pido que todos sean uno, John 17, 21. The GCatholic motto slot and the Wikipedia motto field corroborate it. The message reaches us as an Opus Dei reproduction of Grupo Reforma, not as an archdiocesan original, and that reproduction flag is carried in the reference note; the Scripture words themselves are motto evidence, not a quotation of his words. In September 2019, during his Mexico tenure, three dioceses were erected from the archdiocese, Azcapotzalco, Iztapalapa, and Xochimilco, with Adolfo Miguel Castaño Fonseca, Jesús Antonio Lerma Nolasco, and Andrés Vargas Peña, then Mexico auxiliaries, as their first bishops, and the province of Toluca was erected at the same time, by CEM communiqué Prot. 124/19; that conference document is background only, and no claim is made here that he drove the division.

What he inheritedOpen tenure spanning the Traditionis custodes window; no governing act of his own concerning the 1962 Missal was found for it through as_of. Tridentine Masses are listed as continuing in the archdiocese, at Parroquia de San Pedrito and Capilla Nuestra Señora de Guadalupe per Desde la fe, but no document ties any permission, renewal, or regulation to Aguiar Retes himself, and grantor and date are unestablished; a pre-2018 permission by his predecessor Rivera Carrera is possible but not established and is not asserted. The Guadalajara decree sometimes surfaced in searches is Robles Ortega's act, never his.
