Christian and Jewish relations entered a significant new phase after World War II, in recognition of the unprecedented tragedy of the Holocaust. Among the many influential documents of this news phase are the founding Statement of the International Council of Christians and Jews, "An Address to the Churches" (1947), and the Declaration of the Second Vatican Council, "Nostra Aetate" (1965). The essence of these two documents is their mutual acknowledgment of Christian antisemitism and the urgent need to reverse its devastating consequences. As a result of these and other documents, Christian and Jewish relations have improved, in remarkable and often unexpected ways. Apart from official statements and declarations, however, Christian and Jewish relations are also responding to unprecedented advances in scholarship, which are providing us with forceful reminders that the truth about "us" should never be a lie about "them" regardless of whether "they" are other Christians, or other Jews, or adherents of other faiths, or agnostics and atheists.
