Paul wrote this letter on how to implement the Vatican Council, especially as regards the conciliar documents Christus Dominus (On the Pastoral Office of Bishops), Presbyterorum Ordinis (On the Life and Ministry of Priests), Perfectae Caritatis (On the Adaptation and Renewal of Religious Life), and Ad Gentes (On the Missionary Activity of the Church).

An important new regulation announced in this document is the provision that all bishops, archbishops and Curial officials, from October 11, 1966, were deemed to "voluntarily" offer their resignation to the pope on their 75th birthday.

[3] Another provision of Ecclesiae Sanctae encouraged episcopal conferences and patriarchal synods to "enact regulations and publish norms for the bishops in order to obtain a suitable distribution of the clergy," both in their own area and for the benefit of mission countries.

[4] Vatican II's call for all Catholics to be missionary disciples was advanced further by Paul VI's Apostolic Letter of 1975, Evangelii Nuntiandi.
