1973, the Coptic Patriarch Shenouda III of Alexandria visited the Vatican, where he met three times with Pope Paul VI. A common declaration and a joint Creed issued after the visit proclaimed unity in a number of theological issues, though also that other theological differences "since the year 451" "cannot be ignored" while both traditions work to a greater unity. Anglicans Paul VI was the first pope to receive an Anglican Archbishop of Canterbury, Michael Ramsey, in official audience as Head of Church, after the private audience visit of Archbishop Geoffrey Fisher to Pope John XXIII on 2 December 1960. Ramsey met Paul three times during his visit and opened the Anglican Centre in Rome to increase their mutual knowledge. He praised Paul VI and his contributions in the service of unity. Paul replied that "by entering into our house, you are entering your own house, we are happy to open our door and heart to you." The two church leaders signed a common declaration, which put an end to the disputes of the past and outlined a common agenda for the future. Cardinal Augustin Bea, the head of the Secretariat for Promoting Christian Unity, added at the end of the visit, "Let us move forward in Christ. God wants it. Humanity is waiting for it." Unmoved by a harsh condemnation by the Congregation of Faith on mixed marriages precisely at this time of the visit, Paul VI and Ramsey appointed a preparatory commission which was to put the common agenda into practice on such issues as mixed marriages. This resulted in a joint Malta declaration, the first joint agreement on the Creed since the Reformation. Paul VI was a good friend of the Anglican Church, which he described as "our beloved sister Church". This description was unique to Paul and not used by later popes. Protestants In 1965, Paul VI decided on the creation of a joint working group with the World Council of Churches to map all possible avenues of dialogue and co-operation. In the following three years, eight sessions were held which resulted in many joint proposals. It was proposed to work closely together in areas of social justice and development and Third World Issues such as hunger and poverty. On the religious side, it was agreed to share together in the Week of Prayer for Christian Unity, to be held every year. The joint working group
