Egyptian Contribution to Christianity 305 writer. To this period belong his great works on Christian Philosophy, the frcpl ap^tDv, and the earlier books of a Commentary on St. John, perhaps also the beginnings of a monumental edition of the text of the Old Testament, the Hexapla, containing in six parallel columns the Hebrew, a trans- literation of the Hebrew, the ancient Greek Version of the Seventy and the three later versions of Aquila, Symmachus, and Theodotion. After his settlement at Caesarea in A.D. 231, Origen laboured on unceasingly at his textual and exegetical work, at the same time instructing the whole body of the faith- ful and delivering homilies in the congregation. To this later period there belongs also his great work of Christian Apolo- getics, the Contra Celsum^ in eight books, which has come down to us entire. Finally Origen died a martyr for the Christian faith. In the persecution of Decius he was thrown into prison, where he suffered terrible tortures. On the death of Decius in 251 he was released, but his sufferings had shattered his health and he died two years later at Tyre in the seventieth year of his age. Thus the whole course of Origen's life shows him to have been whole-heartedly identified with the Christian Church. He was a philosophical thinker, but first and last he was a believing and confessing Christian. He begins the Trept dp^oiv with a summary statement of the faith which all believers should and do accept. This rule of faith, with the Scriptures which substantiate the rule, has for him incontestable authority. And the theological principle is in harmony with his practical atti- tude. When the heathen Celsus chides the Christian teachers with being concerned exclusively with 'simpletons, low folk and fools, slaves, womenkind and children', Origen rebuts the charge, but only to insist that the Divine Word does indeed call such as these, though not these alone, 'since the Christ is the saviour of all men, and especially of such as believe, whether prudent or simple'.1 This catholicity of temper distinguishes 1 Contra Celsum^ z. iii. 49.
