Kindly inform me what are the best authorities for a study of the doctrine
of the Trinity, especially in its Old Testament development. - G.J.R.
The doctrine of God as revealed in the O.T. may be studied in such introductions
as those of Oehler and Schultz. When it appears, Dr. A.B. Davidson's Theology
of the Old Testament (in The International Theological Library’)
will probably be the most useful book of its kind in English; meanwhile, some
help may be found in his article, ‘God in (O.T.)’, ‘Hastings’ D.B. vol.2.
It is, of course, to the N.T. that the student will look for direct revelations
as to the existence of distinctions in the Being of God. He should begin by
reading afresh St. John's Gospel, with Westcott's commentary, and then proceed
to the Pauline Epistles, where he will be aided by Lightfoot on Philippians
and Colossians, and by Sanday and Headlam on Romans. From the N.T. he will go
to the Greek and Latin writers of the fourth century, and read Athanasias on
the Incarnation, Basil on the Holy Spirit, the theological orations of Gregory
of Nazianzus, and part of the great work of Augustine on the Trinity. He may
pursue the history of his subject in Dorner's Doctrine of the Person of Christ,
or Ottley's Doctrine of the Incarnation. A more dogmatic treatment of
the doctrine will be found in Canon Mason's Faith of the Gospel, and
Canon Gore's Bampton Lectures for 1891; its philosophical aspect is unfolded
in Mr. Illingworth's Personality, Human and Divine, and Divine Immanence.
The literature is enormous. But the student who begins with the course which
I have ventured to indicate will have laid a secure foundation for further study.
