The Feast of St. John Chrysostom, Patriarch and Doctor of the Church
is today. There is information on him here.

A bright, cheerful, gentle soul; a sensitive heart, a temperament open to emotion and impulse; and all this elevated, refined, transformed by the touch of heaven,—such was St. John Chrysostom; winning followers, riveting affections, by his sweetness, frankness, and neglect of self. In his labours, in his preaching, he thought of others only. "I am always in admiration of that thrice-blessed man," says an able critic , "because he ever in all his writings puts before him as his object, to be useful to his hearers; and as to all other matters, he either simply put them aside, or took the least possible notice of them. Nay, as to his seeming ignorant of some of the thoughts of Scripture, or careless of entering into its depths, and similar defects, all this he utterly disregarded in comparison of the profit of his hearers."
