From the Ecclesia Dei Commission at the Vatican.

The text of the response of His Excellency Bp. Bernard Fellay, Superior General of the Priestly Fraternity of Saint Pius X, requested during the meeting in the Congregation for the Doctrine of the Faith of March 16, 2012, was delivered on April 17, 2012. This text will be examined by the Dicastery and submitted afterwards to the judgment of the Holy Father.

And the comments of Fr. Lombardi at the Holy See Press Office.

“Today’s news means that yesterday Bp. Fellay’s response, that had been requested by Cardinal Levada at the last meeting, was delivered to the Congregation, to the Ecclesia Dei Commission, to the Congregation for the Doctrine of the Faith. Now, this response, it is a reponse that, according to the words of those who could see it, is a very different response from the previous one, and this is encouraging, we proceed forward. But, naturally, we also find in the response the addition of some details or integrations to the text of the doctrinal preamble that had been proposed by the Congregation for a doctrinal agreement, and this response will be discussed, it will be examined first by the Congregation for the Doctrine of the Faith, in one of its meetings of the next few weeks and, afterwards, it will also naturally be examined directly by the Pope. It can be said that steps forward have been taken, that is to say, that the response, the new response, is rather encouraging, but there are still developments that will be made, and examined, and decisions that should be taken in the next few weeks. I think thw wait will not be long because there is the desire to reach a conclusion in these discussions, in these contacts.”

Incredibly exciting news. Now it is a waiting game.
