Are Jews saved because they are God's chosen people?

The Church states in these documents …

It would seem you are giving a level of authority to at least one of these documents which it itself admits it does not have:

The text is not a magisterial document or doctrinal teaching of the Catholic Church, but is a reflection prepared by the Commission for Religious Relations with the Jews on current theological questions that have developed since the Second Vatican Council.

I’m not an expert on this by any means, but Pontifical Commissions are not the Magisterium, although some have been organs of the Extraordinary Magisterium in the past. We need to be careful not to assume that a particular document issued by a Commission is “The Church” stating something. Such documents can contain errors, and we are not bound by them in the same way we are bound to certain channels of Magisterial authority.

Those who claim to be Catholic while calling its teachings nonsense are nothing but nonsense themselves, a poisonous snake, and the devil’s child. I pray that those who do such things repent, for it is one thing to claim the Church to be untrue and a very different thing to do the same while claiming to be Catholic.

You cannot make blanket, categorical statements about these matters and ascribe them to the Church when, in fact, they are not Church doctrine.

The Church states in these documents I’ve cited that it agrees with St. Paul’s word that how God incorporates the Jews into the economy of salvation in Christ as it sees it is still “inscrutable…unsearchable.”–Romans 11:33.

No, the Church never made a doctrinal statement about the matter at hand:

The text is not a magisterial document or doctrinal teaching of the Catholic Church, but is a reflection prepared by the Commission for Religious Relations with the Jews on current theological questions that have developed since the Second Vatican Council.

In other words, the Church understands that it cannot produce any doctrine beyond the revelation given to St. Paul. It remains a mystery…How it works out is not a matter that has been revealed.

See above. You have not cited Church doctrine.
