During his training he studied philosophy in Zaragoza, theology in Pamplona and was ordained a priest in 1968. During the 1970s he studied psychology at the University of Barcelona and afterwards attended Pontificia Universidad Católica de Chile to do research in this field.

In 1983 he was assigned to the Province of Chile as parochial vicar in the Longaví Parish (Diocese of Linares), which was entrusted to the Capuchin Friars.

He was Treasurer of the Chilean Association of Canon Law; promoter of justice in the Ecclesiastical Court of Valparaíso, and psychologist and judge in the Interdiocesan Ecclesiastical Court of Concepción. As a member of special courts to study historical processes in beatification and canonization cases, it was his responsibility to study the miracle for the canonization of priest Alberto Hurtado.

In 2014 Pope Francis appointed him Bishop of the Diocese of Copiapó and on March 23, 2019 the Holy Father appointed him Apostolic Administrator of the Archdiocese of Santiago and he became the Pro-Chancellor of Universidad Católica. In December of the same year, the Pope appointed him Archbishop of the Archdiocese of Santiago and, in accordance with the General Statutes of the University, Monsignor Aós became Chancellor of the UC.
