Jews need to have faith in Christ like anyone else to be saved. Their covenant is intact in its fulfilled form, but they are not faithful to it by refusing to put their faith in Jesus Christ.
The People of God, which in Old Testament times was called “Israel” is now called “the Catholic Church.” It is no longer just for faithful Jews (that is, people of the Jewish race who have embraced Jesus and the fullness of truth) but membership has also been extended tofaithful Gentiles as well. Likewise, Jews who reject the gifts of God by refusing to embrace the Messiah are cut off from the people of God. The Second Vatican Council embraced this doctrine greatly throughout Lumen Gentium (it is why it uses the phrase “People of God”). It also explicitly calls the Church, the “new Israel.”
“Israel according to the flesh, which wandered as an exile in the desert, was already called the Church of God.(96) So likewise the new Israel which while living in this present age goes in search of a future and abiding city (97) is called the Church of Christ.(98)”
) I was praying the Psalms next door to Orthodox Jews who were probably praying the Psalms as well! The chaplins’ offices were arranged so that the Rabbi and a Priest shared an office (meanwhile the Protestant minister and the Muslim sheikh got seperate offices from each other…which is probably for the better!!) That experience got me thinking how we relate to Judaism and why we’re so close to them.
