Moral Grandeur and Spiritual Audacity

I am reading a book by Abraham Joshua Heschel, "Moral Grandeur and Spiritual Audacity".  The book is excellent, and the third of Rabbi Heschel's books that I have bought and read.

Heschel is an interesting character.  Perhaps "was" would be a better word, because he died in 1972, but reading his books makes me like "is" is better, as his writings are so full of life.

He was a Jewish theologian, and he had a special talent for appealing to Christians as much as to Jews, and had many Christian admirers, including Pope Paul VI, who told him that he hoped Catholics would read his books, as it would help them to be better Catholics.
