Radio Cristiandad reports on a conference in Nova Friburgo, Brazil where + Williamson speculates on BXVI's intentions in reaching an agreement with the SSPX. His Excellency states: "I think that there is danger of an agreement before the end of the year, I'm not saying that there will be. But I'm saying there is danger (risk) that there will be".
I found this statement particularly interesting because the Vatican just announced that the pope has already completed his new encyclical on Faith but it will not be made public until January 2013 because he wants to release first his 3rd volume on the life of Christ that is also ready. It doesn't make sense to me to begin the "Year of Faith" in October and wait until January to publish it.
I think the Vatican is waiting to get the SSPX in the bag before they publish it. I also think the new 1962 Missal was delayed for the same reason. It is possible, that the encyclical on Faith, for the "Year of Faith" may be the end of a "reintegrated" SSPX.
