theology. (b) by supplying proofs and illustrations of many truths common to the two sciences. (c) by unfolding and throwing into scientific shape the truths of Revelation. This union was opposed by the 'Positive Teachers' of the Western Church, especially by Tertullian and St Cyprian. Pantaenus' successor was Titus Flavius Clement, Clement of Alexandria. Clement was appointed in 192. His lectures were attended by large numbers of pagans. He commenced with those truths that could be demonstrated from philosophy, for the purpose of leading his hearers by degrees to embrace the Christian faith. He did not confine himself to oral instruction. He wrote numerous works for the benefit of those who could not attend his lectures. In 202 he fled to Palestine because of the persecution of Septimius Severus. After four years he returned". "The first great figures of the Church in Egypt were scholars rather than bishops, directors of the Catechetical School of Alexandria: Clement (160-215) and Origen (185-251). Both were versed in Greek philosophy and their lives' work was one of great integration: they transformed Christianity from a localised cult for the poorest class into a fully-fledged religion with a philosophy and a cosmology." End of this School "The Council of Constantinople, convened in 381", a little while after the death of St. Athanasius of Alexandria, "had far-reaching effects for Egypt". After declaring the primacy of the Bishop of Rome at the expense of Alexandrian authority, riots destroyed the school. "However, it was reopened in a different location in 1893." Origen's work "Origen undertook this great work to vindicate the Septuagint version of the Bible. The original manuscript was preserved in Caesarea, where it was said to have been destroyed by the Arabs when the city was taken by them in 653. It was Origen, who is generally looked on as the father of biblical criticism, that gave the Catechetical School of Alexandria the high character it enjoyed for biblical studies. He was the first to draw a clear distinction between the different senses which Sacred Scripture can have, viz., the literal, the moral, and the mystical or allegorical."
