As has been widely reported, Pope Benedict penned a letter to the world’s bishops about the Williamson boondoggle — and expressed regret for how it was handled.

A snip:

One mishap for me unforeseeable, was the fact that the Williamson case has superimposed itself on the remission of the excommunication. The discreet gesture of mercy towards the four bishops ordained validly but not legitimately, suddenly appeared as something entirely different: as a disavowal of the reconciliation between Christians and Jews, and therefore as the revocation of what in this area the Council had clarified for the way for the Church. The invitation to reconciliation with an ecclesial group separating itself had thus become the opposite: an apparent way back behind all the steps of reconciliation between Christians and Jews which had been made since the Council and which to make and further had been from the outset a goal of my theological work. The fact that this superposition of two opposing processes has occurred and has disturbed for a moment the peace between Christians and Jews as well as the peace in the Church I can only deeply regret. I hear that closely following the news available on the internet would have made it possible to obtain knowledge of the problem in time. I learn from this that we at the Holy See have to pay more careful attention to this news source in the future. It has saddened me that even Catholics who could actually have known better have thought it necessary to strike at me with a hostility ready to jump. Even more therefore I thank the Jewish friends who have helped to quickly clear away the misunderstanding and to restore the atmosphere of friendship and trust, which – as in the time of Pope John Paul II – also during the entire time of my pontificate had existed and God be praised continues to exist.

Another mishap which I sincerely regret, is that the scope and limits of the measure of 21 January 2009 have not been set out clearly enough at the time of the publication of the procedure. The excommunication affects persons, not institutions. Episcopal consecration without papal mandate means the danger of a schism, because it calls into question the unity of the Bishops’ College with the Pope. The Church must, therefore, react with the harshest punishment, excommunication, and that is to call back the persons thus punished to repentance and into unity. 20 years after the ordinations this goal has unfortunately still not been achieved. The withdrawal of the excommunication serves the same purpose as the punishment itself: once more to invite the four bishops to return.
