“To provide the Church with a clear identity for itself, Christian theologians transvaluated Judaism. The Church Fathers turned Jewish values and practices on their heads by misrepresenting them as their opposites. Cyril of Alexandria wrote, “Note that the shadow of the law is reversed and the ancient things of the law are made ineffective.”
“Christian theologians attacked the essential values and practices of Jewishness—the Jews Covenant with the One God, their Chosenness, circumcision, ethical laws, God–wrestling, Messiah, dietary obligations, Sabbath, holy days, patriarchs, and Holy Scriptures. The Church Fathers did this by reinterpreting, modifying, and adapting them to fit the requirements of the Christian self–image and theology. In effect, the Latin and Greek Fathers said to the Jews, “We’ll take your God, your Scriptures, your Messiah, and some of your Law; as for you, you are disinherited, cast into a limbo.”
