Covenant the Key to Scripture

or so believes Benedict:

...Ratzinger holds true to his belief in the “intrinsic unity of the Old and the New Covenant, the two parts of the Holy Scripture,” an awareness he says he acquired “since the very first day” of his early theological studies. He first made his theological views on Judaism public in 1990, when as the cardinal in charge of the Congregation for the Doctrine of the Faith, he was interviewed in “Jews and Judaism in the Universal Catechism,” a piece published simultaneously in Studi Cattolici (in Italian) and Midstream (in English).

He says, “We can read the New Testament only together with what preceded it, otherwise, we would completely fail to understand it...”
