Let Stephen be killed, the Church of Jerusalem dispersed in confusion: out of it go forth burning brands, and spread themselves and spread their flame. For in the Church of Jerusalem, as it were burning brands were set on fire by the Holy Spirit, when they had all one soul, and one heart to God-ward. When Stephen was stoned, that pile suffered persecution: the brands were dispersed, and the world was set on fire.
St. Augustine, Sermon 66 on the New Testament
