I'm going to have to paraphrase, as I'm too lazy to bother searching for the exact scriptural quote, but here goes:
I was raised Catholic, and was given a Catholic bible when I was 'confirmed' in the faith at age 12. I mostly ignored it, of course, because at the age of 12 I wasn't much interested in theological propositions. But I did keep the book.
Many years later, when I was recovering from chronic alcoholism, it was suggested to me by my mentors in AA that I revisit the religion of my youth, and see what's there that may be able to help me learn how to live life as a sober man. So I did as they suggested, and for the first time, really, began to read the bible cover to cover.
I don't know if you all are aware of this, or not, but the Catholic bible has a book in it that the protestant bible do not have. It's called the Book of Wisdom, and is apart from Ecclesiastes. In the Book of Wisdom the author writes a lot about wisdom itself, in rather poetic terms, as though wisdom is a female spirit, and I was taken by the artistry of images and ideas being presented in this book. As I read, I came across the line "and man is punished through that with which he sins". As you might imagine, as a recovering alcoholic, this line struck home with me. And more then that, there was a long story/explanation of this assertion using the final deadly plague upon the Egyptians as it's lesson example. It explained in detail just we are indeed punished through the mechanism of our own sins. It was a kind of in depth explanation of the mechanics of karma. And as I read this, fascinated, I was clobbered with yet another revelation: and that was that it was NOT GOD who was punishing us for our sins, but the SINS THEMSELVES!
Reading the Book of Wisdom at that time in my life completely changed and opened up my understanding of Christ and Christianity, a religion that I had long ago rejected. It struck me so hard, that I soon joined a progressive bible discussion group that a friend was attending and continued to participate in that group for years. The old Catholic religion that I was raised with fell away, and a new vision of Christianity was born in my mind, that made sense to me in my heart. And it really did all come from that one line: "... for man is punished through that with which he sins".
