Jung on Christianity by Carl Jung

From Memories, Dreams, Reflections, pp. 52–63

With my father it was quite different. I would have liked to lay my religious difficulties before him and ask him for advice, but I did not do so because it seemed to me that I knew in advance what he would be obliged to reply out of respect for his office. How right I was in this assumption was demonstrated to me soon afterward. My father personally gave me my instruction for confirmation. It bored me to death. One day I was leafing through the catechism, hoping to find something besides the sentimental-sounding and usually incomprehensible as well as uninteresting expatiations on Lord Jesus. I came across the paragraph on the Trinity. Here was something that challenged my interest: a oneness which was simultaneously a threeness. This was a problem that fascinated me because of its inner contradiction. I waited longingly for the moment when we would reach this question. But when we got that far, my father said, "We now come to the Trinity, but we'll skip that, for I really understand nothing of it myself. " I admired my father's honesty, but on the other hand I was profoundly disappointed and said to myself, "There we have it; they know nothing about it and don't give it a thought. Then how can I talk about my secret?"
