The Lambeth Conference is convened by the Archbishop of Canterbury, the most senior archbishop in the Anglican church, every ten years. He invites over 800 archbishops and bishops of all ranks from the worldwide Anglican Communion to meet for worship, study and conversation. It is called the Lambeth Conference because the Archbishop of Canterbury's palace is at Lambeth, in London, England. Bishops from other churches held to be 'in communion' with the Anglican church, including bishops from the Episcopal Church in the United States and a number of guests from other faiths, are also invites.
