On one ordination day St. Francis de Sales noticed a young priest. When the ceremony was over, he remarked that at the door of the church the newly ordained stopped as though he were disputing with some invisible person as to who to pass first. "What is it?", the Saint asked. The young levite confessed that he had the privilege of seeing his guardian angel. "Before I was a priest," he said, "he always went in front of me, but now he will no longer pass before me." The angels are not priests, but they reverence in us that dignity which they adore in Christ.
