The boy reached through to the Soul of the World, and saw that it was part of the Soul of God. And he saw that the Soul of God was his own soul. And that he, a boy, could perform miracles.
There is nothing that God hath established in a constant course of nature, and which therefore is done every day, but would seem a Miracle, and exercise our admiration, if it were done but once.
I can believe a miracle because I can raise my own arm. I can believe a miracle because I can remember. I can believe it because I can speak and be understood by you.
A miracle is an event which creates faith. That is the purpose and nature of miracles. Frauds deceive. An event which creates faith does not deceive: therefore it is not a fraud, but a miracle.
In the Catholic Church, there are many other things which most justly keep me in her bosom. The consent of peoples and nations keeps me in the Church; so does her authority, inaugurated by miracles, nourished by hope, enlarged by love, established by age. The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep (Jn 21:15-19), down to the present episcopate.
