In the field of multilateral relations, the major partner of the Catholic Church is the World Council of Churches (WCC). Founded in 1948, it is the broadest and most inclusive ecumenical organization, bringing together 350 Christian denominations including Orthodox, Lutherans, Reformed, Anglicans, Methodists, Baptists as well as United and Independent churches. Altogether they represent over 500 million Christians worldwide.
On 18 October 2019, the Pontifical Council for Promoting Christian Unity (PCPCU) presented the official Catholic Response to The Church: Towards a Common Vision (TCTCV), Faith and Order Paper No.214, published in 2013. Passing through many intermediate stages, the TCTCV is the result of two decades of intense theological work prepared by Orthodox, Anglican, Protestant, Evangelical, Pentecostal and Roman Catholic theologians.
