Edition note 1
Of the early life of Ambrose, the friend of Origen, we know nothing. We learn from Origen’s Exhortatio ad Martyr. c. 14, and Jerome’s de vir. ill. c. 56, that he was of a wealthy and noble family (cf. chap. 23 of this book), and from the Exhort. ad Mart. c. 36, that he probably held some high official position. Eusebius says here that he was for some time a Valentinian, Jerome that he was a Marcionite, others give still different reports. However that was, the authorities all agree that he was converted to the orthodox faith by Origen, and that he remained devoted to him for the rest of his life. From chap. 23 we learn that he urged Origen to undertake the composition of commentaries on the Scriptures, and that he furnished ample pecuniary means for the prosecution of the work. He was also himself a diligent student, as we gather from that chapter (cf. also Jerome, de vir. ill. c. 56). From chap. 28 we learn that he was a confessor in the persecution of Maximinus (Jerome calls him also a deacon), and it seems to have been in Cæsarea or its neighborhood that he suffered, whither he had gone undoubtedly on account of his affection for Origen, who was at that time there (cf. the Exhort. c. 41). He is mentioned for the last time in the dedication and conclusion of Origen’s Contra Celsum, which was written between 246 and 250 (see chap. 36, below). Jerome ( l.c. ) states that he died before Origen, so that he cannot have lived long after this. He left no writings, except some epistles which are no longer extant. Jerome, however, in his Ep. ad Marcellam, §1 (Migne’s ed., Ep. 43), attributes to Ambrose an epistle, a fragment of which is extant under the name of Origen (to whom it doubtless belongs) and which is printed in Lommatzsch’s edition of Origen’s works, Vol. XVII. p. 5. Origen speaks of him frequently as a man of education and of literary tastes and devoted to the study of the Scriptures, and Jerome says of him non inelegantis ingenii fuit, sicut ejus ad Origenen epistolæ indicio sunt (l.c.). The affection which Origen felt for him is evinced by many notices in his works and by the fact that he dedicated to him the Exhortatio ad Martyr ., on the occasion of his suffering under Maximinus. It was also at Ambrose’s solicitation that he wrote his great work against Celsus, which he likewise dedicated to him.
