About IARCCUM

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-presidency of Archbishop Donald Bolen and Bishop David Hamid.

In October of 2016, IARCCUM gathered 19 pairs of Anglican and Roman Catholic bishops in Canterbury and Rome for an 8-day pilgrimage. This gathering was an opportunity to study and pray together at the tombs of Saints Peter, Paul, Augustine of Canterbury, and Thomas à Becket. The bishop-pairs were commissioned by Pope Francis and Archbishop of Canterbury, Justin Welby at vespers at San Gregorio al Celio. On the site where St Gregory the Great commissioned St Augustine to evangelise the English, these bishops were commissioned to promote the growth in communion between these two churches and the reception of the agreements reached in the theological dialogues.
