I believe Berkhof goes over this in his prolegomena, though I might be mistaken.
If Berkhof has book or chapter called, Prolegomena, I couldn’t find it. Bavinck has a volume called: Prolegomena.
Reformed Dogmatics, Volume 1: Prolegomena, by Herman Bavinck
Berkhof does say, in his:
Introductory Volume to Systematic Theology, that he thinks the term Dogmatic Theology is better than Systematic Theology, immediately after stating that the two terms are a primarily a matter of “popular appeal;” yet he called his work,
Systematic Theology.
Reformed scholars in Germany and in the Netherlands show a decided preference for the title
Dogmatics, with or without a modifier. In our own country, however, the term
Systematic Theology seems to have a more popular appeal.
From an ideal point of view the former certainly deserves preference, (1) because it is the more specific of the two, and designates the real object of study with greater precision; and (2) because the modifier ‘systematic’ in ‘Systematic Theology’ is apt to create the impression that the study under consideration is the only theological study which treats its subject-matter in a logical order, or that among the theological
discipline there is no other that is systematic in structure; and this is not true. For practical reasons, however, it seems more desirable, especially in our country and in our day, to use the title
Systematic Theology. This does not require the sacrifice of any principle. Dr. Warfield even considers this title better than the other, and therefore comes to its defense. *
