Andrés Sáinz Márquez

Andrés Sáinz Márquez was born on 16 August 1969 at Arandas, in the Diocese of San Juan de los Lagos, matching the roster birth date; the bulletin states no civil state, so no state is added. He studied at the seminary of San Juan de los Lagos and was ordained a priest on 27 April 1996, incardinated in the Diocese of San Juan de los Lagos. He took the licentiate in psychology from the Universidad del Valle de Atejamac in Guadalajara. The bulletin lists his offices, undated, as parish vicar, parish administrator, parish priest of various communities, and dean; at his appointment he was parish administrator of Santa Maria Traspontina, spelled exactly as the bulletin prints it, without an accent, and its location is not established, so Arandas is not asserted for it. Pope Francis appointed him bishop prelate of Jesús María on 26 February 2025.

CONSECRATION TIER FLAG: his consecration date, 18 June 2025, rests on the Catholic-Hierarchy June 2025 events page (opened: 18 Jun, 'Ordained Bishop,' Prelate of Jesús María del Nayar) and the roster, and is NOT diocesan-primary. No diocesan-primary confirmation, consecrator, venue, or separate installation date was found in any search, so no consecrator is inferred (in particular the metropolitan is not assumed to have been principal) and the 26 February 2025 appointment date is not substituted. Per the rule for an ordinary consecrated for his see, the tenure codes from consecration. Jesús María del Nayar is a territorial prelature, so as prelate he is its ordinary. No motto, work, or quotable fragment was found in any opened source; a secondary blog's 'doctor in human development' is not carried, since the bulletin states a licentiate in psychology. He held no prior episcopal office; he was a diocesan priest until June 2025.
