As Catholics and Anglicans, we are humbly grateful that, after centuries of mutual mistrust, we are now able to recognize that the fruitful grace of Christ is at work also in others. We thank the Lord that among Christians the desire has grown for greater closeness, which is manifested in our praying together and in our common witness to the Gospel, above all in our various forms of service. At times, progress on our journey towards full communion may seem slow and uncertain, but today we can be encouraged by our gathering. For the first time, a Bishop of Rome is visiting your community. It is a grace and also a responsibility: the responsibility of strengthening our ties, to the praise of Christ, in service of the Gospel and of this city.
