Dominican preaching is sometimes described, and for good reason, as doctrinal since it delights in pondering and proclaiming the mysteries of Creation, Incarnation, Redemption and Resurrection. But the manner in which Dominican preachers, like Catherine and Thomas, speak about imbibing the wine of the mystery of Christ, alerts us to the fact that real "knowing" is always accompanied by a certain amazement. The wine of truth which Christ gives us to drink is also a wine of astonishment. What we preach, then, are not just truths about God. We preach a wine of truth which we have actually tasted ourselves, and have drunk with living faith and joy.
