In his October 28 op-ed, Rabbi Noam Marans wrote that the Vatican II document Nostra Aetate affirmed “the validity of God’s ongoing covenant with the Jewish people.”
This is a common error. To this day, the Roman Catholic Church rejects the Dual Covenant Theory, which would have acknowledged that we Jews have our own path to salvation. It continues to affirm that the only way to salvation is via the church (see the Catechism of the Catholic Church 846).
Confirming this analysis of the church’s position, in 2009 the U.S. Conference of Catholic Bishops removed from the “U.S. Catechism for Adults” the sentence: “Thus the covenant that God made with the Jewish people through Moses remains eternally valid for them.”
