some worldly institutions and systems, such as much of the transitional conservative Anabaptist church systems,
The Holdeman men I see on a regular basis wear T-shirts and jeans and are basically indistinguishable from many worldly men.
As I understand it, Holdemans diverged from worldly clothing sometime in the 1960s.
The implication, of course, is that to be outwardly more conservative or traditionally "plain" is to have less worldliness and thus more Christlikeness; as if the cut of a man's suit, the amount of buttons on his shirt, or the difference between a knee-length skirt and an ankle-length skirt has anything to do with worldliness.As I said earlier, the problem with moderate conservatives is the transitional nature of (some) of them, where they have a steady stream in the front door of people from more-conservative backgrounds (and a steady stream out the back door of people heading for even more worldly places).
"Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still worldly—mere infants in Christ. 2 I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. 3 You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere humans?"
For where there is strife, jealousy, impatience, hasty generalizations, false reporting, being overly swift to speak (or type), answering a matter before hearing it, prideful retorts, harsh judgments, and so on, there is worldliness. Here worldliness can be found, on MennoNet itself. And in every human heart, in the old man that must be put off every day. Not in the differences between Pilgrim and Midwest Conference. Nor can it be escaped by moving to Tennessee, or Bolivia, or to a convent, or to the top of a pole in Egypt.
This type of worldliness is exactly what the Bible says will happen when we adopt the false gospel of asceticism that says implementing more external restrictions will lead to more spirituality and holiness. (This does NOT mean that you need to e.g. start watching movies to be more holy - although I have no problem with a discerning, thoughtful enjoyment of that audio-visual format - nor that you can be more worldly and be closer to Christ. No one thinks that). As Col. 2:23 notes, they have an appearance of wisdom, but no real value against fleshly desires. It leads to passing judgement on one another (Rom. 14:13), treating one another with contempt (14:10), and spiritual pride - comparing ourselves among ourselves, concluding people are an utterly lost cause, etc.
I respect a desire to just follow Christ, be more like Christ, etc., and to want others to follow Him. Having that desire does not mean that one has an accurate view of the world. Much like the proverbial blind men feeling different parts of an elephant, people who want to follow Christ exist in many different denominations. Don't despise the faith of the one who left what seemed a dead formalism to find a faith in a church that looks different from yours, even if you personally found that you had to join a more restrictive setting to find what seems to be a serious commitment.
