Tertullian\u27s Apologeticum is justly renowned. It is renowned because of its author, Tertullian, who because of the diction, style, extent, and time of his writings is recognized generally as the father of Church Latin. There is no doubt that later writers, among them men of such importance as St. Augustine, Ambrose, and Cyprian, were influenced by him. Of Cyprian it is said that be called Tertullian simply the teacher. And yet, important as all the writings of Tertullian are, many of them have now lost their claim to the attention of all except the specialist and the historian. But not so his Apologeticum; that retains its significance for all, and parts of it are still quoted in sermons and theological literature
