which declared Anglican holy orders "absolutely null and utterly void" and rejected Anglican positions on the branch theory and apostolic succession. The official reply of the archbishops of the Church of England was Saepius officio. The judgement remains in effect to the present. Malines Conversations Some attempts at dialogue began in 1915, when Pope Benedict XV approved a British Legation to the Vatican, led by an Anglican with a Roman Catholic deputy. However, discussion of potential reunion in the Malines Conversations eventually collapsed in 1925. Continued efforts resulted in the spread of the Week of Prayer for Christian Unity in both churches (and others) and the visit of George Bell, the Anglican Bishop of Chichester, to Cardinal Montini of Milan, later Pope Paul VI. Second Vatican Council Real rapprochement was not achieved until the warming of Roman Catholic attitudes to ecumenism under the leadership of Pope John XXIII, whose foundation of the "Secretariat for the Promotion of Christian Unity" encouraged the then Archbishop of Canterbury, Geoffrey Fisher, to make a historic, though not entirely official, visit to the Vatican in 1960. Subsequently, the Bishop of Ripon, John Moorman, led a delegation of Anglican observers to the Second Vatican Council. In 1966, the Archbishop of Canterbury, Michael Ramsey, made an official visit to Pope Paul VI and, in the following year, the Anglican-Roman Catholic International Commission was established. Building on Pope Paul VI's description of the Anglican Church as "our beloved Sister Church", there has been considerable productivity in these discussions, but progress was not without difficulty. Anglican-Roman Catholic International Commission Greater rapprochement was achieved in 1966, with the visit of Archbishop Michael Ramsey to Pope Paul VI. The following year, the Anglican-Roman Catholic International Commission was established. Its first project focused on the authority of scripture. The commission has since produced nine agreed statements. Phase One of ARCIC ended in 1981 with the publication of a final report, Elucidations on Authority in the Church. Phase Two lasted between 1983 and 2004 and a third phase is expected. The most recent agreed statement dealt with Marian theology and was published in 2004. In 2000, following a successful meeting of Anglican and Roman Catholic bishops in Mississauga in Canada, a new commission, the International Anglican-Roman Catholic Commission for Unity and Mission, was established to promote practical co-operation between Anglicans and Roman Catholics and the reception of the fruits of the theological dialogue.
