Can Jews go to heaven?
Yes, they can, and indeed salvation is from the Jews, as Jesus Christ teaches (John 4:22). But anyone who is saved is saved by Jesus Christ, the Jewish Messiah and Savior of all mankind, and through his Catholic Church (see CCC 846-848). In addition, we should not presume upon the salvation of non-Catholics, nor on our own salvation. For more on the Church’s teaching on salvation, see this article from Catholic Answers Magazine.
