José Luis Mollaghan

José Luis Mollaghan (2 May 1946 – 7 June 2025) was an Argentinian prelate of the Roman Catholic Church. From 2014 he was an official of the Congregation for the Doctrine of the Faith. He had previously held positions in Argentina, including Auxiliary Bishop of Buenos Aires and Archbishop of Rosario.

Biography Mollaghan was born in Buenos Aires, Argentina. After the seminary he studied philosophy and theology at the Seminary of the Immaculate Conception of the Archdiocese of Buenos Aires.

In 1967 he obtained his licentiate in theology and a degree in canon law at the Pontifical Gregorian University in Rome. Because the commission had not been established, he moved to Buenos Aires to signify his release from responsibility for the Rosario diocese. He told a congregation at a festive celebration in Rosario in August: "The technical director decides the changes. I just wanted to stay in Rosario, but he sent me to Buenos Aires to make work easy for me." He remained in Argentina, living in Buenos Aires for several months, before moving to Rome. The seven-member Commission was established on 11 November 2014 with responsibility for sexual abuse of minors, heresy, apostasy, misuse of the sacrament of penance, and the ordination of women. Argentine newspapers interpreted Mollaghan's assignment in Rome as an "elegant" way to remove him from Rosario following an investigation into the mismanagement of church funds and referred to Mollaghan as "an old rival" of the pope. Mollaghan denied that he represented a more conservative faction of the Argentine hierarchy and pointed to his long service alongside Bergoglio in Buenos Aires.

Mollaghan died on 7 June 2025, at the age of 79.
