There was a remarkable day when the Jewish Catholics or Catholic Jews – whichever you want to call them – arrived, nuns and priests wearing the yellow star on their habits. I remember two young novices, twins with identical beautiful, dark ghetto faces and serene, childish eyes peering out from under their skullcaps. They said with mild surprise that they had been fetched at half past four from morning mass, and that they had eaten red cabbage in Amersfoort.

There was a priest, still fairly young, who had not left his monastery for fifteen years. He was out in the ‘world’ for the first time, and I stood next to him for a while, following his eyes as they wandered peacefully around the barracks where the newcomers were being received. […]

I looked at the priest who was now back in the world again. ‘And what do you think of the world now?’ I asked. But his gaze remained unwavering and friendly above the brown habit, as if everything he saw was known, familiar from long ago. That same evening, a man later told me, he saw some priests walking one behind the other in the dusk between two dark barracks. They were saying their rosaries as imperturbably as if they had just finished vespers at the monastery. And isn’t it true that one can pray anywhere, in a wooden barracks just as well as in a stone monastery, or indeed, anywhere on this earth where God, in these troubled times, feels like casting his likeness?

Klaas, all I really wanted to say was this: we have so much work to do on ourselves that we shouldn’t even be thinking of hating our so-called enemies. […]

And I repeat with the same old passion, although I am gradually beginning to think that I am being tiresome, ‘It is the only thing we can do, Klaas, I see no alternative, each of us must turn inward and destroy in himself all that he thinks he ought to destroy in others. And remember that every atom of hate we add to this world makes it still more inhospitable.’

And you, Klaas, dogged old class fighter that you have always been, dismayed and astonished at the same time, say, 'But that – that is nothing but Christianity!’

And I, amused by your confusion, retort quite coolly, 'Yes, Christianity, and why ever not?’
