One should not lightly dismiss the existence of such historical untruths on the assumption that there is always a grain of truth in every myth. Sometimes a myth is completely false, as in the case of murdered princes. Moreover, this type of myth is sometimes very harmful. We need only remind ourselves of the infamous ritual-murder myth, suggesting that the Jews used the blood of a Christian child for ritual purposes. <1> It is undeniable that throughout the ages many Christians took an active part in the persecution of Jews. [43] This fact has been officially and repeatedly admitted by Christian bodies. Some of the statements in this documentation unequivocally plead guilty in this respect. Small wonder, then, that many Christians, as well as Jews, honestly believe that "there was a complete and terrible silence on the part of the Church" [44]. In the process of creation of anti-Jewish myths, there is a tendency to generalize: "The Jews have ..." We like to think in general terms because stereotypes are so easy, whilst it costs us much more mental effort to discriminate. Let us not commit the same offence against logic as the anti-Semites have and let us remember that it is just as fallacious to talk about "the Churches" as about "the Jews". It is important for many reasons not to overrate the positive things the Churches did and said. It is also important, again for many reasons, not to belittle them. We certainly must denounce acts of anti-Semitism, even when outstanding leaders of the Church were the perpetrators, but this remains a negative. We must also mention the positive, which is more encouraging. I believe this is one of the underlying intentions of "Yad Vashem's" competent Department in trying to seek out and honour the "righteous of all Nations": non-Jews who helped Jews at the risk of their own lives. [45] It seems far too early to come to a definite evaluation of many aspects of the holocaust. Far be it from me, to claim that I can say the last word about that one aspect under discussion here: the attitude <2> of the non-Roman Catholic Churches. I can and must try to be objective, but I cannot be detached, as probably none of our generation can: we were all involved, in one way or another. [46] But I am convinced that our generation can and must do the groundwork. It must collect the material that may otherwise be completely lost or forgotten, and investigate it before even more people, who were personally involved, have passed away.
