Pontifical Commission Ecclesia Dei

The Pontifical Commission Ecclesia Dei (Latin: Pontificia Commissio Ecclesia Dei) is a commission of the Catholic Church established by Pope John Paul II's motu proprio Ecclesia Dei of 2 July 1988 for the care of those former followers of Archbishop Marcel Lefebvre who broke with him as a result of his consecration of four priests of his Society of St. Pius X as bishops on 30 June 1988, an act that the Holy See deemed illicit and a schismatic act.

It has the additional tasks of trying to return to full communion with the Holy See those traditionalist Catholics who are in a state of separation, of whom the Society of Saint Pius X (SSPX) is foremost, and of helping to satisfy just aspirations of people unconnected with these groups who want to keep alive the pre-1970 Roman Rite liturgy.

Pope Benedict XVI gave the Commission additional functions on 7 July 2007, and on 8 July 2009 he made the Prefect of the Congregation for the Doctrine of the Faith the ex officio head of the Commission.

According to Bernard Fellay, superior general of the Society of Saint Pius X, in 2000, Cardinal Darío Castrillón Hoyos, who became President of the Commission in that year, approached the bishops of the SSPX about regularizing relations, and told them that the Pope was prepared to grant them a personal prelature without territorial limits — the same canonical structure as that enjoyed by Opus Dei. According to William Dinges, it was the society that launched a petition drive calling for a personal prelature at least five years earlier.
