Those which have been in constant use in the preparation of this chapter have been an excellent article by Th. Förster in the Theologische Studien und Kritiken for 1888, p. 645 ff., and two full and valuable papers by Dr. Baltzer on the Theologie and Christologie of Hilary in the Programm of the Rottweil Gymnasium for 1879 and 1889 respectively. I have unfortunately not had access to Wirthmüller’s work, Die Lehre d. hl. Hil. über die Selbstentäusserung Christi, but the citations in Baltzer and Schwane give some clue to its contents. The Introduction to the Benedictine edition is useful, though its value is lessened by an evident desire to make Hilary conform to the accepted opinions of a later age. Dorner’s great work on the Doctrine of the Person of Christ, in the English translation, with the Dogmengeschichte of Schwane (ed. 2, 1895) and that of Harnack (ed. 3, 1894) have also been constantly and profitably consulted. Indebtedness to other works is from time to time acknowledged in the notes.
