He was consecrated on 29 June 1973 by Pope Paul VI. In 1974, the Congregation published a "declaration on procured abortion", re-asserting the Church's opposition to the controversial procedure since the publication of Humanae Vitae. He later helped in writing the document Persona humana on the topic of sexual ethics.
He remained at this position until Pope John Paul II appointed him Pro-Prefect of the Congregation for Institutes of Consecrated Life and Societies of Apostolic Life in 1984. At that time the title of Prefect was reserved for someone who was already a Cardinal.
Cardinalate
He became Prefect of the Congregation when he was made Cardinal-Deacon of San Saba in the consistory of 25 May 1985, two days after which the full title was formally granted him. He resigned as the head of the Congregation on 21 January 1992. He opted for the order of Cardinal Priests after ten years and his deaconry was elevated pro hac vice to title on 29 January 1996. He lost the right to participate in a conclave when he turned 80 in 1996. He died on 2 December 1996 in Rome.
