Betty,
Thank you for this most important notation. By Voegelin's reasoning all of culture, but especially Western culture is the very expression of Christian thought. As to discussions of ID or of the establishment clause in our Constitution, neither science nor our government have the ability to stand on their own independent from Christian thought.
If one accepts the premise that there is a unity of truth in creation - and not an infinite variety of subjectivity - Christianity stands at the apex of that truth.
Is this to say that all other religions are false? Certainly not, simply less evolved. ;)
I do accept that premise; and agree with the conclusion you draw from it, Amos.
Thank you so very much for writing!
