Nostra Aetate initiated a revolutionary shift in Catholic theology, opposing supersessionism and affirming that Jews remain in a salvific covenantal relationship with God. However, this shift raises for Catholics a deep tension regarding the value of this “Old Covenant” vis-à-vis the “New Covenant,” as this article illustrates using the statements of Walter Kasper and The Gifts and the Calling of God Are Irrevocable. While speaking positively about the Old Covenant, both deem it essential to maintain the superiority of the New Covenant as universalistic, fulfilling the promises in the Old Covenant and transcending its limitations. The author demonstrates how they seek to reduce this tension by characterizing the two covenants as good and better covenants, rather than as bad and good covenants, thereby avoiding a lapse into supersessionism.
