Recently, I've been racked at the possible ways this belief might be construed when someone says it. I suspect that the primary Biblical basis for it is John 1, but as we know, there can be many interpretations for just a single verse, depending on your assumptions and starting points.
So when a Christian says "Jesus is the Word", what is an overview of the various beliefs that this Christian may ascribe to?
NOTE: I do not want to focus on general christological overviews. I realize this question is indeed a christology question, but I want to be sure that answers focus exclusively on what Christians mean when they say this phrase and how that relates to their theological perspective (which you don't have to explain, just name).
