Superb words from Pope Benedict XVI
"Nourished and sustained by the Eucharist, Catholics cannot but feel stimulated to tend towards that full unity for which Christ hoped in the Cenacle. Peter's Successor knows that he must take on this supreme desire of the Divine Master in a particularly special way. To him, indeed, has been entrusted the duty of strengthening his brethren.
Thus, in full awareness and at the beginning of his ministry in the Church of Rome that Peter bathed with his blood, the current Successor assumes as his primary commitment that of working tirelessly towards the reconstitution of the full and visible unity of all Christ's followers. This is his ambition, this is his compelling duty. He is aware that to do so, expressions of good feelings are not enough. Concrete gestures are required to penetrate souls and move consciences, encouraging everyone to that interior conversion which is the basis for all progress on the road of ecumenism.
Theological dialogue is necessary. A profound examination of the historical reasons behind past choices is also indispensable. But even more urgent is that "purification of memory," which was so often evoked by John Paul II, and which alone can dispose souls to welcome the full truth of Christ. It is before Him, supreme Judge of all living things, that each of us must stand, in the awareness that one day we must explain to Him what we did and what we did not do for the great good that is the full and visible unity of all His disciples.
The current Successor of Peter feels himself to be personally implicated in this question and is disposed to do all in his power to promote the fundamental cause of ecumenism. In the wake of his predecessors, he is fully determined to cultivate any initiative that may seem appropriate to promote contact and agreement with representatives from the various Churches and ecclesial communities. Indeed, on this occasion too, he sends them his most cordial greetings in Christ, the one Lord of all."
