For a long time during those frightful years [of the Holocaust and World War II] I waited for a great voice to speak up in Rome. I, an unbeliever? Precisely. For I knew that the spirit would be lost if it did not utter a cry of condemnation when faced with force. It seems that that voice did speak up. But I assure you that millions of men like me did not hear it and that at that time believers and unbelievers alike shared a solitude that continued to spread as the days went by and the executioners multiplied.
It has been explained to me since that the condemnation was indeed voiced. But that it was in the style of the encyclicals, which is not at all clear. The condemnation was voiced and it was not understood! Who could fail to feel where the true condemnation lies in this case and to see that this example by itself gives part of the reply, perhaps the whole reply, that you ask of me. What the world expects of Christians is that Christians should speak out, loud and clear, and that they should voice their condemnation in such a way that never a doubt, never the slightest doubt, could rise in the heart of the simplest man. That they should get away from abstraction and confront the blood-stained face history has taken on today. The grouping we need is a grouping of men resolved to speak out clearly and to pay up personally. When a Spanish bishop blesses political executions, he ceases to be a bishop or a Christian or even a man; he is a dog just like one who, backed by an ideology, orders that execution without doing the dirty work himself. We are still waiting, and I am waiting, for a grouping of all those who refuse to be dogs and are resolved to pay the price that must be paid so that man can be something more than a dog.
