Many need instruction as to how they should appear in the assembly for worship on the Sabbath. They are not to enter the presence of God in the common clothing worn during the week. All should have a special Sabbath suit, to be worn when attending service in God’s house. While we should not conform to worldly fashions, we are not to be indifferent in regard to our outward appearance. We are to be neat and trim, though without adornment. The children of God should be pure within and without. Testimonies For the Church, vol. 6, 355

Many will not attend the service of God upon the Sabbath because their dress would appear so unlike that of their Christian sisters in style and adornment. Will my sisters consider these things as they are, and will they fully realize the weight of their influence upon others? By walking in a forbidden path themselves, they lead others in the same way of disobedience and backsliding. Christian simplicity is sacrificed to outward display.

My sisters, how shall we change all this? How shall we recover ourselves from the snare of Satan and break the chains that have bound us in slavery to fashion? How shall we recover our wasted opportunities? how bring our powers into healthful, vigorous action? There is only one way, and that is to make the Bible our rule of life. All should work earnestly to do good to others, watch unto prayer, take up the long-neglected cross, and heed the warnings and injunctions of Him who has said: “Whosoever will come after Me, let him deny himself, and take up his cross, and follow Me.”  Testimonies for the Church, vol. 4, 631
 
All who meet upon the Sabbath to worship God should, if possible, have a neat, well-fitting, comely suit to wear in the house of worship. It is a dishonor to the Sabbath, and to God and His house, for those who profess that the Sabbath is the holy of the Lord, and honorable, to wear the same clothing upon the Sabbath that they have worn through the week while laboring upon their farms, when they can obtain other.  Review and Herald, January 23, 1900 

Some receive the idea that in order to carry out that separation from the world which the word of God requires, they must be neglectful of their apparel. There is a class of sisters who think that they are carrying out the principle of non-conformity to the world by wearing an ordinary sunbonnet, and the same dress worn by them through the week, upon the Sabbath, to appear in the assembly of the saints to engage in the worship of God.

And some men who profess to be Christians view the matter of dress in the same light. They assemble with God’s people upon the Sabbath, with their clothing dusty, and soiled, and even with gaping rents in them, and placed upon their persons in a slovenly manner. This class, if they had an engagement to meet a friend honored by the world, and they wished to be especially favored by him, would exert themselves to appear in his presence with the best apparel that could be obtained; for this friend would feel insulted were they to come into his presence with hair uncombed, and garments uncleanly, and in disorder. Yet these persons think that it is no matter in what dress they appear, or what is the condition of their persons, when they meet upon the Sabbath to worship the great God. They assemble in His house, which is as the audience-chamber of the Most High, where heavenly angels are in attendance, with but little respect, or reverence, as their persons and clothing indicate. Their whole appearance typifies the character of such men and women. Selected Messages, Book 2, 475 

If there are worthy persons who, with their whole heart would honor the Lord of the Sabbath, and the worship of God, and who cannot obtain a change of clothing, let those who are able, donate to such a Sabbath suit, that they may appear in the house of God with cleanly, fitting apparel. Those who expend means on costly apparel and extra fixings, can by a little self-denial exemplify pure religion, by simplicity of clothing, and then use the means they have usually expended needlessly in aiding the poor to obtain neat and modest apparel. The Health Reformer, February 1, 1872
