Carlton Wynne objects to natural law and its influence among Reformed Protestants:
I believe this aspect of the Natural Law theory in view–that people can reason their way to actionable truths apart from God’s special revelation–is too optimistic about the powers of unaided reason after the fall. The general revelation of God in nature and beneath conscience must be “carefully distinguished from the reaction that sinful man makes to this revelation” (Van Til). The apostle Paul says that unbelievers “suppress the truth” that they know (including the truth of their moral obligation to God), that they are, at root, “hostile to God” (Rom 8:7); that they have become “futile in their thinking” (Rom 1:21). They are, Paul says elsewhere, “darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart” (Eph 4:18).
These are hard words, no doubt. But they point to one side of what has been called the “antithesis” between belief and unbelief, a moral and spiritual conflict of basic commitments that touch all that Christians and non-Christians think about and discuss. According to this Scriptural principle, fallen man is slavishly committed to his own moral autonomy, while Christians are to view all things under the Lordship of Christ and the light of His Word. This means that, at the deepest level, there is no mutually acknowledged common ground between Christian and non-Christian. And this, it seems to me, leaves NL proponents calling for peace when there is no peace.
If true, do you then only go to Christian physicians?
And if true, why would you ever let non-Christians into positions of political authority? If you assert the antithesis you wind up theonomic.
Will “common grace” really explain why you, a person who believes in the anti-thesis, choose a non-Christian physician or politician over Christian ones?
