On June 28, 2011 a delegation from the Ecumenical Patriarchate of Constantinople made their traditional visit to Rome for the Feast of Apostles, Peter and Paul.
Pope Benedict is the "Pope of Christian Unity". In his first Papal message he proclaimed, "Nourished and sustained by the Eucharist, Catholics cannot but feel encouraged to strive for the full unity for which Christ expressed so ardent a hope in the Upper Room. The Successor of Peter knows that he must make himself especially responsible for his Divine Master's supreme aspiration. Indeed, he is entrusted with the task of strengthening his brethren (cf. Lk 22: 32). With full awareness, therefore, at the beginning of his ministry in the Church of Rome which Peter bathed in his blood, Peter's current Successor takes on as his primary task the duty to work tirelessly to rebuild the full and visible unity of all Christ's followers. This is his ambition, his impelling duty."
There is a growing collaboration between the Orthodox and Catholic Churches in efforts to slow the collapse of Christian influence in European culture. There have been other signs of the Spirit at work in pulling these Churches to a along the path toward reestablishing communion.
