Those preachers are foolish and improvident who, in speaking of religion and proclaiming the things of God, use no words but those of human science and human prudence, trusting to their own reasonings rather than those of God. Their discourses may be brilliant and fine, but they must be feeble and they must be cold, for they are without the fire of the utterance of God (Jeremiah 23:29).
--Pope Leo XIII, Providentissmius Deus
