Popes Paul VI, John Paul II and Benedict XVI have all met with the Patriarchs of Constantinople. It is a sign of progress. However you have to remember, the Patriarchs of Individual Orthodox Churches do not have any more authority than any other bishop in the Orthodox Church, they are the Ordinary Bishop of the See that is the Mother of each National Church (more or less) and while they are looked to for advice and leadership, they are one among many, and cannot make a unilateral decision.

We should all pray as Jesus did, that we may all be one.
