into the royal family was removed in 2013, though they cannot become monarch since as such they would be the head of the Church of England. Apostolicae curae In 1896 Pope Leo XIII issued Apostolicae curae rejecting the Anglo-Catholic claims of the Oxford Movement and the Chicago-Lambeth Quadrilateral, such as apostolic succession. In it Leo XIII declared Anglican orders "absolutely null and utterly void." The official reply of the Archbishops of the Church of England was Saepius officio. The judgment remains in effect to the present. The judgment of nullity was reaffirmed in 1998 by the Congregation for the Doctrine of the Faith, when it gave Apostolicae curae as an example of the authoritative teaching of the Catholic Church. Early ecumenism Some attempts at dialogue began in 1915, when Pope Benedict XV approved a British Legation to the Vatican, led by an Anglican with a 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, Bishop of Chichester, to Cardinal Giovanni Montini of Milan in 1955. Post–Second Vatican Council developments Real rapprochement was achieved under the leadership of Pope John XXIII, whose foundation of the "Secretariat for the Promotion of Christian Unity" encouraged Archbishop 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, Archbishop Michael Ramsey made an official visit to Pope Paul VI, and in the following year, the Anglican–Roman Catholic International Commission (ARCIC) was established. Its first project focused on the authority of Scripture, and 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 has been ongoing since 1983. The most recent agreed statement dealt with Marian theology, and was published in 2004. Paul VI went so far as to refer to the Anglican Church as "our beloved sister Church", though this description might not tie in with present thinking in the Vatican. Until recently it was used by the website of the Roman Catholic Ampleforth College (referring to Anglican pupils at that school). "Given the significant extent of our
