The Pontifical Council for Promoting Christian Unity (PCPCU) origins are associated with the Second Vatican Council which met intermittently from 1962–1965.
Pope John XXIII wanted the Catholic Church to engage in the contemporary ecumenical movement. He established a "Secretariat for Promoting Christian Unity" on 5 June 1960 as one of the preparatory commissions for the Council, and appointed CardinalAugustin Bea as its first president. The Secretariat invited other Churches and World Communions to send observers to the Council.
Description
The Secretariat prepared and presented a number of documents to the Council:
With the doctrinal commission, the Dogmatic Constitution on Divine Revelation (Dei verbum).
Following the Second Vatican Council, in 1966 Pope Paul VI confirmed the Secretariat for Promoting Christian Unity as a permanent dicastery of the Holy See.
In the Apostolic Constitution Pastor Bonus (28 June 1988), Pope John Paul II changed the Secretariat into the Pontifical Council for Promoting Christian Unity.
The PCPCU has two sections dealing with:
The Eastern Churches - The Eastern and Oriental Orthodox Churches as well as the Assyrian Church of the East;
The PCPCU is responsible for naming Catholic observers at various ecumenical gatherings and in its turn invites observers or "fraternal delegates" of other Churches or ecclesial Communities to major events of the Catholic Church.
At present, the PCPCU is engaged in an international theological dialogue with each of the following Churches and World Communions:
The Council is responsible for working with other Churches on ecumenical translations of Sacred Scripture, and promoted the establishment of the Catholic Biblical Federation.
