In 2000, Archbishop George Carey and Cardinal Edward Cassidy, the then President of the 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, and whether closer co-operation could be developed between the two traditions. The result was the International Anglican–Roman Catholic Commission for Unity and Mission (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.
IARRCUM's work continues under the Co-Chairmanship of Archbishop Don Bolen and Bishop David Hamid.
In 2016 IARCCUM made a pilgrimage from Canterbury to Rome, where pairs of bishops were commissioned by Pope Francis and Archbishop Justin Welby.
IARCCUM has an online resource centre for Anglican-Roman Catholic relations which can be found at www.iarrcum.org
