Task: Question Generation
Input (English): 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.
Output (English): To what type of non Catholic denomination was Paul VI considered to be a great ally of?
