On December 2nd, 55 years ago, Pope John XXIII had a private audience with the Archbishop of Canterbury Geoffrey Fisher, the first time that Anglican and Catholic leaders had met together since the Reformation. Following their historic encounter, the archbishop met with Cardinal Augustin Bea, head of the newly established Secretariat for Christian Unity, leading to the invitation of Anglican observers to the Second Vatican Council. The meeting also paved the way for the first official encounter between their successors, Pope Paul VI and Archbishop Michael Ramsey in March 1966 and the establishment of an Anglican Centre here in Rome.
