Excerpt: ON the death of Theophilus, Archbishop of Alexandria, in A. D. 412, his nephew and successor, S. Cyril, comes suddenly before us. For of S. Cyril's previous life we have only a few scattered notices. We do not know in what year he was born, nor any thing of his parents, nor where he was brought up. That S. Cyril had received a thoroughly good education, is abundantly clear; not only from his very extensive reading, which a mind of such large grasp as S. Cyril's would ever provide for itself, but that his reading being so well digested implies good early training. The great accuracy of his Theology implies a most accurate Theological education. That education included a large range of secular study as well as of Divinity, and probably comprised a good deal of learning by heart, not only of the holy Scriptures but also of profane authors, as witness a line of Antipater Sidonius quoted in his Commentary on Zechariah. He quotes too Josephus on the Jewish war. On Hab. 3:2, he mentions interpretations of that verse of two different kinds: on Hosea he gives a long extract from a writer whom we do not apparently possess. Tillemont remarks, that "his books against Julian shew that he had a large acquaintance with secular writers." We may infer that S. Cyril was brought up at some monastery, as a place of Christian education, and from the great reverence which he ever paid to S. Isidore, Abbot of Pelusium, it seems not unlikely that S. Isidore was his instructor during some part of his early life. S. Isidore alludes to some especial tie, in one of his brief letters to S. Cyril, when Archbishop. Near the beginning, S. Isidore says, "If I be your father as you say I be, ... or if I be your son as I know I am, seeing that you hold the chair of S. Mark &c." The large number of Platonic words in S. Isidore's letters seem to indicate that he too had extensive reading of Plato, and S. Cyril may have acquired from him some of his knowledge of Aristotle. But a mind of S. Cyril's grasp would feel itself lost in the desert, yearning for its own calling, and another Letter of the same S. Isidore to S. Cyril, reproaching him with his heart being in the world, may belong to this period. His uncle Archbishop Theophilus had him to live with him and, we may infer, ordained him priest and made him one of his Clergy. Excerpt: Much of these quiet years S. Cyril probably employed on his earlier writings: of these, two were on select passages of the Pentateuch; one volume being allotted to those which S. Cyril thought could in any way be adapted as types of our Lord, the other to the rest, as being types of the church. The commentaries on Isaiah and the Minor Prophets and the Books against the Emperor Julian probably belong to this period. Besides these S. Cyril, following the example of his great predecessor S. Athanasius, wrote two Books against the Arians: first, the Thesaurus, in which S. Cyril brought to bear his knowledge of Aristotle; then the de Trinitate, which was written, though not published till later, before A. D. 424. In his Paschal homily for that year A. D. 424, S. Cyril also speaks of the Eternal Generation of the SON, and towards the close of the homily he opposes the Arian terms "Generate," "Ingenerate." A. D. 429, the circulation of tracts of Nestorius in Egypt occasioned him first to write on the heresy of Nestorius. There can be little doubt that the powerful mind of S. Leo, who was the soul of the Council of Chalcedon, was, in his young days when S. Celestine's Archdeacon in 429, taught through those writings; as S. Cyril himself had been taught by the writings of S. Athanasius.
