"The greatest challenge to the ecumenical movement in general, and to the Anglican-Roman Catholic relationship in particular, is its success. The ecumenical movement has been so successful, that most of us have no memory of the pre-ecumenical climate that existed even in some of our own lifetimes. Happily, most of us have no memory of the poisonous state of Anglican-Roman Catholic relations prior to 1966, when the Archbishop of Canterbury, Dr. Michael Ramsey, visited Pope Paul VI in Rome. .... This visit created the Anglican Centre in Rome. Renewed global relationships between Roman Catholics stemmed from all of these initiatives". In the 1960s "[w]ho would have believed that Roman Catholic bishops would have concelebrated the Eucharist in the crypt of Canterbury Cathedral one day, and that on the next a Roman Catholic archbishop would have preached at the main Sunday Eucharist in the cathedral ?" "The events in Rome in 1966 and in Canterbury and Rome in 2016 are simply miraculous. They defy history, leaving us full of hope and wonder for what God has in store for us next".
