Online resource centre for Anglican-Roman Catholic relations

Welcome to the International Anglican-Roman Catholic Commission for Unity and Mission (IARCCUM) website, an online resource centre for Anglican-Roman Catholic relations.


IARCCUM is a commission established by the Anglican Communion and the Roman Catholic Church as an official joint commission. IARCCUM exists in parallel with the Anglican-Roman Catholic International Commission, the theological commission known as ARCIC. IARCCUM’s purpose is:

In 2000, Archbishop George Carey, then Archbishop of Canterbury, and Cardinal Edward Cassidy, then President of the Vatican’s Pontifical Council for Promoting Christian Unity, convoked a conference of Anglican and Roman Catholic bishops at Mississauga in Canada to discern the progress made in theological conversations since the 1960s, and whether closer co-operation could be developed between the two traditions. The result was IARCCUM, which has been meeting since 2001. In February 2007, it published the first fruit of its work, the report Growing Together in Unity and Mission, accompanied by two commentaries. IARCCUM’s work continues under the Co-Chairmanship of Bishop Donald Bolen and Bishop David Hamid.
