met the Anglican Archbishop of Canterbury, Rowan Williams. In their Common Declaration, they highlighted the previous 40 years of dialogue between Catholics and Anglicans while also acknowledging "serious obstacles to our ecumenical progress". On 4 November 2009, in response to a 2007 petition by the Traditional Anglican Church, Benedict issued the apostolic constitution Anglicanorum coetibus, which authorized the creation of "Personal Ordinariates for Anglicans entering into full communion." Between 2011 and 2012, three ordinariates were erected, currently totalling 9090 members, 194 priests, and 94 parishes. Interfaith dialogue Judaism When Benedict ascended to the papacy, his election was welcomed by the Anti-Defamation League who noted "his great sensitivity to Jewish history and the Holocaust".

This prayer has historically been contentious in Judaic-Catholic relations and several groups saw the restoration of the Tridentine Mass as problematic. Among those whose excommunications were lifted was Bishop Richard Williamson, an outspoken historical revisionist sometimes interpreted as a Holocaust denier. The lifting of his excommunication led critics to charge that the Pope was condoning his historical revisionist views. Islam Benedict's relations with Islam were strained at times. On 12 September 2006, he delivered a lecture which touched on Islam at the University of Regensburg in Germany. He had served there as a professor of theology before becoming Pope, and his lecture was entitled "Faith, Reason and the University—Memories and Reflections". The lecture received much attention from political and religious authorities. Many Islamic politicians and religious leaders registered their protest against what they labelled an insulting mischaracterization of Islam, although his focus was
