St. John was the Archbishop of Constantinople during the fourth century. He was fearless when denouncing sin in high places, and was a prolific writer, and bold preacher, unafraid to hit the topical issues of the day squarely between the eyes with all the subtlety of a ball peen hammer. He had many powerful enemies, but they feared him, and had him banished. He had to march, at the age of 60, to the place of his banishment, and died on the way. His last words were “Glory to God for all things!”
Now, that’s great preaching.
