An excerpt with emphasis mine:
The excommunication of the bishops consecrated by His Grace Archbishop Marcel Lefebvre, on June 30, 1988, which had been declared by the Congregation for Bishops in a decree dated July 1, 1988, and which we had always contested, has been withdrawn by another decree mandated by Benedict XVI and issued by the same Congregation on January 21, 2009.
We express our filial gratitude to the Holy Father for this gesture which, beyond the Priestly Society of Saint Pius X, will benefit the whole Church. Our Society wishes to be always more able to help the pope to remedy the unprecedented crisis which presently shakes the Catholic world, and which Pope John Paul II had designated as a state of “silent apostasy.”
