It is legitimate to affirm that

The gap between the Catholic and Orthodox Church is not very wide. We have almost everything in common. It seems to me, in fact, that the question we must ask ourselves is not so much whether we can re-establish full communion, but rather whether we still have the right to remain separated. The sin of our separation is very serious. May the Lord open our hearts, convert our minds and inspire in us concrete, courageous steps, capable if necessary of breaking through clichés, easy resignation or stalemate. The deepest nature of the Church demands it. - St. John Paul II (1920-2005)
