"For as many as are led by the Spirit of God, they are the sons of God." Ro. 8:14 That sounds to me a global affair. Doesn't it to you?
Timeless truths resonate throughout all cultures. It's only someone who is unable to discern what those are, who try to find truth in some externalized form, do what fundamentalists do and try to turn back the hands of time's advance to a "simpler" or "purer" time and do what the early "believers" did, since they "had it" in their eyes. The only advantage to understanding the cultural backdrop is to provide a context to understand with the mind the sorts of impact or penetration those truths must have had to give a hint to what that applied truth might have in today's contexts. It provides a hint, not a realization.
The message of God, this timeless Truth lives in all creation, is seen and known in all creation, and is understood in creation, today and before the year zero. But to be clear, we are not talking relative cultural truths, but timeless eternal Truth. It is through knowing that we are able to apply it in relative terms to the culture we are in. Never, are those dogmatic and inflexible or absolutist.
