Pope Benedict resigns. A sensational report from Rome, special programs, reports, recaps: The issue is all the rage. Never since Celestine V in 1294, a pope has resigned. [Gregory XII]
The pontificate was marked by Benedict's attempt to find a canonical solution for the SSPX. Already in 2009, the pontiff had withdrawn the unjust Excommunication against the four bishops consecrated by Archbishop Lefebvre.
Unjust because Archbishop Lefebvre did not wish to split with the consecration, but wanted to save the tradition.
