We must never separate the Spirit and the Word. The Spirit speaks to us through the Word; so we should always doubt and query any supposed revelation that is not entirely consistent with the Word of God. Indeed the essence of wisdom is to reject altogether the term “revelation” as far as we are concerned, and speak only of “illumination.” The revelation has been given once and for all, and what we need and what by the grace of God we can have, and do have, is illumination by the Spirit to understand the Word.
