Context: St. Francis is not only the most attractive of all the Christian saints, he is the most attractive of Christians, admired by Buddhists, atheists, completely secular, modern people, Communists, to whom the figure of Christ himself is at best unattractive. Partly this is due to the sentimentalization of the legend of his life and that of his companions in the early days of the order. Many people today who put his statue in their gardens know nothing about him except that he preached a sermon to the birds, wrote a hymn to the sun, and called the donkey his brother. These bits of information are important because they are signs of a revolution of the sensibility — which incidentally was a metaphysical revolution of which certainly St. Francis himself was quite unaware. They stand for a mystical and emotional immediate realization of the unity of being, a notion foreign, in fact antagonistic, to the main Judeo-Christian tradition.
“I am that I am” — the God of Judaism is the only self-sufficient being. All the reality that we can know is contingent, created out of nothing, and hence of an inferior order of reality. Faced with the “utterly other,” the contingent soul can finally only respond with fear and trembling.
