I do not know what all the theological consequences of this may be, but I do know God swore on His own honor that He would be faithful even if His people were not faithful...
The Church does not teach, in her Magisterium, this very extreme and sweeping theological opinion: that every single gift, promise, ordinance and bond God ever made with the Jews is forever revoked and rejected.
True, many of His promises have already been fulfilled by Christ or by the Church as the "ingrafted branch" of the Jewish olive tree. But some of these promises to the Jews have yet to be fulfilled, because the time of their fulfillment--- the End of the Age-- has not yet come.
All of the eminent Catholic Jews, people like Alphonse Ratisbonne, the late Cardinal Lustiger, the Venerable Francis Liberman, and St. Teresa Benedict of the Cross (Edith Stein)--- have understood themselves to be as Catholics saved by Christ, while still members of the Chosen People with a role to play in Salvation History as Jews.
Yes, the Jews have a role in Salvation History from Abraham to the Second Coming. That is NOT the same as saying that they, or anyone, can be saved without faith in Christ.
It is not up to you, Hofmannor, or Bergoglio to declare the End of Age is now upon us and the Jews are now saved.
That is a sin of presumption. It is better to pray for their conversion, both collectively and privately, at this time.
