On page 86 of Reflecting the Divine Image, Dunning says "Some popular bible teachers suggest that here we have an Old Testament reference to the Trinity, a New Testament truth. This is anachronistic. I believe the best way to explain these references that suggest a plurality in God is to interpret them to mean that God has a social nature, interpersonal in character."

Any one up to explaining this to me? I have heard the first part before, and it worked for me. I can't picture how one can "suggest a plurality in God" without it meaning the Trinity. Unless Dunning is trying to say that 'we can't go so far as to pinpoint three persons in that plurality' in which case I can see that somewhat. It is a rather vague statement nonetheless.
