From my Colson Center article ‘The Abstraction of God and the Culture Wars‘:
In talking about sexual morality, it is typical to find pastors, Christian spokespersons and lay people alike, operating as if there can never be any question of a right-ordered nature that precedes and animates God’s commands: we simply need to know what the rules are and to keep them.
Under such a scheme, all the ordering of our world is deliberate ordering and creation becomes radically contingent. It thus becomes difficult to speak of certain sexual patterns as being “rightly ordered” or “fitting” in any sense more general than, or prior to, God’s pedestrian commands.
Indeed, it is easy to slip into assuming that for God to be truly free and all-powerful, the categories by which our moral and material lives are ordered must be wholly the result of God’s disposing will and not rooted in structures antecedent to His commands, such as the fixities of His nature that find expression in the inherent patterns embedded in creation’s design.
Among evangelicals from legalistic backgrounds, this functional nominalism often finds expression in the notion that the only objective criteria for making decisions is sin-avoidance. In areas where the category of sin does not apply, the only criteria to influence our decisions is personal subjective choice. There are thus no categories with which to talk meaningfully about the telos of a thing, or the internal logic of nature’s ordering, independent of moral questions about right and wrong.
This type of abstraction from teleology turns creation into a playground for us to do with as we like provided we do not sin, while the criteria for determining what counts as sin is truncated to specific divine commands interpreted independently from the teleological-directedness of how creation is. (The recent flare-up in Moscow Idaho’s food debates hinge on this very problem, as do some of the modern music myths that have taken the church captive in recent years.)
