PD, you are way out of line on this one. I doubt any of us would defend the standards as a thorough, consistent, praiseworthy charter for Christian community but to loosely and erroneously wield the warning passages you cited concerning false teachers is absurd. Whether you intend to or not you have wrongly indicted godly, gospel-savoring faculty and staff who uphold them (whether they agree or not) as accomplices.
As I wrote to you before, "legalism" is a favorite term of slander in evangelical circles and is rarely used correctly. Its not wise behavior (I will not be alone with another woman), or cultural behavior (I will keep my Bible off the floor in Muslim settings), or community-conscious behavior (I will not invite someone to drink without knowing where they stand). Properly defined legalism is behavior that strives to earn salvation. It can be any of the former examples or none of them. Our heart is the issue. Knowing my spiritual laziness I can place the strictest of standards on myself and still revel in the free grace of the gospel alone. But I can also throw off all standards entirely and revel in my self-righteousness for doing so. The right set of standards (behavior, culture, community) does not automatically preclude which I will do.
You have failed to account for the “amoral” standards in the New Testament: widows must be 60 to receive charity (1 Tim 5.9), do not eat food sacrificed to idols (1 Cor 8.12), or drink wine in certain circumstances (Ro 14.21), “abstain from the things polluted by idols” (Ac 15.20), don’t pursue circumcision after conversion (1 Cor 7.18), let only 2-3 persons speak in tongues and prophecy in any given service (1 Cor 14.27), eat at home before gathering to celebrate communion (1 Cor 11.34). These standards are a blend of wisdom, culture, and community-consciousness and yet they still leave a lot of effeminate, adolescent ground uncovered. Paul was able to articulate a robust, grace-filled gospel in one breath and deliver these standards in the next without jeopardizing his message and so can we. I’m not putting, say, CIU’s prohibition of shorts to class on par with Paul’s advice in terms of Christian wisdom, but that is a question of the caliber of the standard and not the appropriateness of standards in general. If your gospel is so frail in the face of standard suggestions, what will become of it when the NT writers’ take off the gloves for moral imperatives (Ti 2.11ff; Heb 12.4; 1 Pt 1.17; Jas 1:25; 1 Jn 2.15; Rev 2:5, 23)?
I am willing to be wrong, but you appear to be pressing legalist charges where they simply won’t stick.
