Vos defines Biblical Theology
Biblical theology, rightly defined, is nothing else than the exhibition of the organic progress of supernatural revelation in its historic continuity and multiformity. (Geerhardus Vos, “The Nature and Aims of Biblical Theology,” The Union Seminary Magazine 13, 1902, p. 196)
For those interested in further study, Geerhardus Vos is often considered the “father of Reformed Biblical Theology.” You can find many of his books and articles online here.
Thanks for this link. One day I’ll pick up his Biblical Theology and re-attempt a read (thesis stress blew out the last attempt). For now, I’ll start with some articles (I need to dip my toes back in the biblical theology pond).
