During the later history of Christianity, several figures became known for their sermons or a particularly significant sermon. Preachers of the early church include Peter (see especially Acts 2:14b–36), Stephen (see Acts 7:1b–53), Tertullian, John Chrysostom, Gregory Nazianzus. Sermons in this era were used to spread Christianity across Europe and Asia Minor. During the Middle Ages, sermons inspired the beginnings of new religious orders (e.g., Saint Dominic and Francis of Assisi). Pope Urban II began the First Crusade in November 1095 at the Council of Clermont, France, when he exhorted French knights to retake the Holy Land in Palestine.
