The first major document to come from Cardinal-Elect Ladaria was a very good document clarifying what Pelagianisn and Gnosticism are--especially the "neo" kind. What I found fascinating is that it appeared to me that Archbishop Ladaria was clarifying Pope Francis' use of these terms which have always struck me as, let me say diplomatically, WRONG!
Then we had heard that Archishop Ladaria had issued a document to the German bishops saying that it was inopportune to have inter-communion with Protestant spouses only to have Pope Francis seemingly turn that around and asking the Germans to work it out for themselves without any definitive direction from the Pope which enraged many in the Vatican including the former prefect of the Congregation for the Faith Cardinal Mueller.
I think this set in motion appeals from Cardinal Volkee the orthodox Cardinal in Germany and others as well as Cardinal-elect Ladaria and thus we have Pope Francis telling the heterodox bishops "no."
Then we had Cardinal Ladaria issue yet again another declaration from his office over the decades that it is a part of the Ordinary Magisterium of the Church that Holy Orders can only be received by men.
This is what I think really impressed me, because if you read between the lines, it is really Pope Francis who is causing the recovery of 1970's thinking on so many issues that have been well-settled under the last two pontificates. We can't live as though Pope St. John Paul II and Pope Benedict had no papacies.
This is what Cardinal Ladaria wrote:
The prefect says "it is a matter of serious concern to see the emergence in some countries of voices that question the definitiveness of this doctrine." By “sowing these doubts creates serious confusion among the faithful not only about the sacrament of orders as part of the divine constitution of the church, but also about how the ordinary magisterium can teach Catholic doctrine in an infallible way,”
Here is Cardinal-Elect Luis Ladaria's letter:
