The Old Testament makes note that we should worship God in the beauty of holiness, Psalm 29:2; 96:9;
Thus, the Bible puts an emphasis on our inward condition for how we are to approach worship.
However, does that mean clothing never is a reflection of our sense of holiness or the condition of our spirit??
(It is interesting that the NASB changes these verses to worship in holy attire, or in holy array. The NASB translators held that people in the time of 1,000 B.C. were too ignorant to understand a concept like the beauty of holiness, and therefore, these verses have to refer to wearing nice clothes. Thus, the verses serve as an example of how superior, modern day scholarship renders a more literal translation of Scripture referring to what the verses literally mean as determined by academic experts, rather than what the verses actually say, which just misleads and confuses modern day people who are still ignorant.)
Anyone who has personally experienced God manifesting his presence will testify how awesome the event is. One never forgets it. When it happens, there is a sense of power in the room that is overwhelming and instantly one is keenly aware that great respect must be shown. There is no time to think on how casual one might be in reaction, but immediately there is a great concern to be at one's holy best. Historically, Pentecostals have been aware of this fact-- that striving for holiness and showing respect for God has an affect on the Holy Spirit manifesting during a service. If there was ever any question of where to draw a line, it was always decided in making the very best effort to please God. Today, Pentecostals spend a lot of time wondering why the Holy Spirit does not manifest during services as he did in the past and yet, they are quick to point out all the things Pentecostals did wrong in the past.
However, it appears that the type of dress referenced in starting this thread did not actually bear on the members striving for the presence of God, but the clothing clearly distinguished between the sexes. This distinction in dress is clearly Biblical. People say there should be no dress code, but if the men are wearing dresses and make-up, and the women are in vested, three piece, pin-stipped suits with ties, then all of a sudden these same people say there is a Christian dress code. At one time, a woman wearing pants was considered masculine. That much has changed, but in Christian society, the pants are usually of a feminine design. The secular world in modern times blurs the distinction between the sexes and very often, it is the first sign of a society going in a direction of non-Christian morality. Some Christian women want to purge the church of an anti-women bias, and there should not be such prejudice but just how close in appearance to secular society should the end result be for the role of women? Is it crazy to want to maintain the distinction in the role of the sexes that God has in mind, to prefer to make the extra effort to ensure such clarity?
I do not believe in dress codes per se, but I emphasize there should be reflection on our inward condition. I have seen churches turn the issue of dress into a fashion show, which is truly disgusting. However, I do not believe it is proper to ignore entirely to what extent dress can reflect our inner sense of what we are.
Here are some other verses in the Bible which do refer to the significance of the clothing we wear as believers.
Exodus 19:10-16
And the LORD said unto Moses, Go unto the people, and sanctify them to day and to morrow, and let them wash their clothes, And be ready against the third day: for the third day the LORD will come down in the sight of all the people upon mount Sinai. And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death: There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount. And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes. And he said unto the people, Be ready against the third day: come not at your wives. And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.
Deuteronomy 22:5
A woman shall not wear anything that pertains to a man, nor shall a man put on a woman's garment; for whoever does these things is an abomination to the LORD your God.
I Corinthians 11:3-16
But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God. Every man praying or prophesying, having his head covered, dishonoureth his head. But every woman that prayeth or prophesieth with her head uncovered dishonoureth her head: for that is even all one as if she were shaven. For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered. For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man. For the man is not of the woman; but the woman of the man. Neither was the man created for the woman; but the woman for the man. For this cause ought the woman to have power on her head because of the angels. Nevertheless neither is the man without the woman, neither the woman without the man, in the Lord. For as the woman is of the man, even so is the man also by the woman; but all things of God. Judge in yourselves: is it comely that a woman pray unto God uncovered? Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him? But if a woman have long hair, it is a glory to her: for her hair is given her for a covering. But if any man seem to be contentious, we have no such custom, neither the churches of God.
I Peter 3:1-7
Likewise you wives, be submissive to your husbands, so that some, though they do not obey the word, may be won without a word by the behavior of their wives, when they see your reverent and chaste behavior. Let not yours be the outward adoring with braiding of hair, decoration of gold, and wearing of robes, but let it be the hidden person of the heart with the imperishable jewel of a gentle and quiet spirit, which in God's sight is very precious. So once the holy women who hoped in God used to adorn themselves and were submissive to their husbands, as Sarah obeyed Abraham, calling him lord. And you are now her children if you do right and let nothing terrify you. Likewise you husbands, live considerately with your wives, bestowing honor on the woman as the weaker sex, since you are joint heirs of the grace of life, in order that your prayers may not be hindered.
