Spanish blog La Cigüeña de la Torre (the first to report that the decree of removal of excommunications was imminent) reports this evening that a special letter has been received at the Apostolic Palace:
A joint letter of the four Bishops ordained by Archbishop Lefebvre was received in the Apostolic Palace, in which they thank the Holy Father for the lifting of the excommunications.The letter, written in French, is very affectionate and conciliatory.
La Cigüeña also informs that Bishop Richard Williamson "has ceased [his functions] as director of the Seminary of La Reja [Argentina]". This information has not yet been confirmed. [UPDATE: Bp. Williamson's editor has told us that he has NOT ceased his functions as head of the SSPX seminary in La Reja, Argentina.]
