(Tim, w/thanks to Mick) Excellent post by Doug Wilson. If you want to read him, don't bother; but if you don't want to read him, you simply must.
In passing, let me note here that, at the first meeting I attended of the Council on Biblical Manhood and Womanhood--the organization that gave us that mincing eight-syllable construction "complementarianism"--several of the more prominent council members shut down an attempt by a younger man to get CBMW to oppose women combatants in our armed forces.
It was clear the thought of CBMW making any statement about the application of God's Order of Creation outside the Christian home and church petrified them. Manhood and womanhood were private truths for the people of God, only.
It was much like the approach taken by Covenant Theological Seminary's resident ethicist David Jones who...way back in 1999, sought the repeal of sodomy laws. Taking on himself the responsibility of responding to my letter addressed to Prof. Jones, Covenant's president at the time, Bryan Chapell, wrote assuring me that Jones wasn't going soft on homosexuality. The lesson?
The application of God's Order of Creation outside the Christian church and home scares the pants off Reformed academics. And they're not even R2K...
