“Emeritus” Ratzinger and Francis are two sides of the same coin.
It was common knowledge that one of the goals of BXVI was to bring traditionalists (namely the SSPX) to Rome. With them in mind and for this purpose he concocted Summorum Pontificuм. A trap +Fellay fell into.
As John Vennari predicted shortly after BXVI took office, he had the potential of fractioning the traditional movement since he knew well all the main figures inside out as cardinal.
Thanks to (mainly) +Williamson, who kept exposing the plans and intentions of +Fellay taking the SSPX to Rome at any cost, the plans failed and BXVI became tired of waiting because Rome was too anxious to get “the New Evangelization” (or “Evangelical Catholicism”) going which is nothing more than the One World Church as prophesied by Anna Katherine Emmerick.
Yes, it’s true the Vatileaks, the Homo Mafia, Bank scandals…played a part but have you noticed how the Vatican Banking is suddenly all "in order"? They sold the Church to the enemy. BXVI wanted traditionalists "reintegrated" before all this to keep them under control. Nothing else.
There have been interviews with the secretary of the “two popes”, Archbishop Ganswein (the latest on Secretum Meum Mihi 1/4/14) in which he stresses there is NO conflict or disagreement between the two, just "different emphasis", "same theology"...
BXVI moved over for Francis to come in and take the Barque of Peter to its enemies which BXVI with his “conservative” facade could not do.
