Francis and Benedict have been in perfect agreement from the beginning as AB Ganswein has been saying.
In his book, The Spirit of the Liturgy, published in 2000, Ratzinger made it clear that two rites are too difficult to manage therefore eventually they would have to be merged into one. Summorum Pontificum is the means to that end. It authorized all the changes that are coming to the 1962 missal while still calling it the "1962" missal. Once that missal is promulgated, the previous (in use now) would have to be abrogated or it would defeat the purpose.
According to the announcement by Una Voce Malta, ONLY the SSPX Prelature will be given a temporary exemption
to keep the current one. Any indult community that want the current one would have to go under the SSPX, those who don't will have to use the new BUT when the SSPX exemption expires, the new version will be the only one in use.
I should mention that shortly after Benedict was elected, he attended the (2005 or 2006) CELAM Conference
(Conference of Latin American and the Caribean Bishops) in the city of Aparecida, Brazil
. At that conference, the "Aparecida Document" was concocted with Bergoglio as the most valuable contributor and the reason he was quickly elected. In 2007, 2 weeks
before Summorum Pontificum was released, Benedict gave the Aparecida Document it's final approval (the link below starts with Benedict's Letter). Why is this important? Because five days
after the last conclave, Francis announced that the "Aparecida Document" (and another I forgot) were the "footprint of his papacy". This was known from a letter sent by Francis to the CELAM bishops. "The New Evangelization" (new religion) is based on those two documents.https://docs.google.com/file/d/0B9XFGc_BZfpPcmNHUkR1Nm8xQjg/edit
Two months before his resignation, The Vatican Insider quoted Benedict stating: "This is the end of the old Church and the beginning of the new". Then came his last talk to all the priests of the Diocese of Rome known as 'The Real Council vs. the Virtual Council'
meaning, they were going to witness now what VII really intended.
The article linked below from 6/29/2016 titled Ratzinger bendice la "revolución Bergoglio
", ("Ratzinger Blesses Francis' revolution) dispels any idea they are not like minded. Lastly, as AB Ganswein has repeatedly stated, "The only difference between "the two popes" is ONLY in style.http://blogs.periodistadigital.com/elbaronrampante.php/2016/06/29/ratzinger-bendice-la-revolucion-bergogli
