It's certainly an unclear area, because of the wide ambit of meanings, even before we get to the Christians. Even before we get to the theology, my small dictionary provides "saying, speaking, speech, mode of speaking, eloquence, discourse, conversation, talk, word, expression, assertion, principle, maxim, proverb, oracle, promise, order, command, proposal, condition, agreement, stipulation, decision, pretext, fable, news, story, report, legend, prose-writing, history, book, essay, oration, affair, incident, thought, reason, reckoning, computation, reflection, deliberation, account, consideration, opinion, cause, end, argument, demonstration, meaning, value, proportion' and then it adds 'New Testament the Word'.
One may take one's pick.
