Charles H. Spurgeon on Psalms 100:3

It is he that hath made us. The emperor Henry, while out hunting on the Lord's day called Quinquagesima, his companions being scattered, came unattended to the entrance of a certain wood; and seeing a church hard by, he made for it, and feigning himself to be a soldier, simply requested a mass of the priest. Now that priest was a man of notable piety, but so deformed in person that he seemed a monster rather than a man. When he had attentively considered him, the emperor began to wonder exceedingly why God, from whom all beauty proceeds, should permit so deformed a man to administer his sacraments. But prescntly, when mass commenced, and they came to the passage, Know ye that the Lord he is God, which was chanted by a boy, the priest rebuked the boy for singing negligently, and said with a loud voice, It is he that hath made us, and not we ourselves. Struck by these words, and believing the priest to be a prophet, the emperor raised him, much against his will, to the archbishopric of Cologne, which see he adorned by his devotion and excellent virtues.
