Yeah, the term "enlightened" is problematic and does not really jibe with Christian teaching. I think a way of sort of answering the question in Christian terms is that Christians and those seeking Christ have access to the one source of eternal truth. However, this does not mean that Christians are somehow "superior" in any way shape or form. Having access to God should lead to an attitude of humility toward God and man (Jesus taught [and still teaches] his followers to be servants and not to think for a moment that they are superior to anyone). It's a shame far too many people miss that, but I guess that's a subject for another thread. Also, what any particular individual, whether they call themselves Christian or not, chooses to do with that knowledge is an entirely different matter. But, again, I'm not sure I would refer to it as "enlightenment" because, at least to me, that term has connotations that simply do not apply to Christian teaching.
