The love of dress endangers the morals and makes woman the opposite of the Christian lady, characterized by modesty and sobriety. Showy, extravagant dress too often encourages lust in the heart of the wearer and awakens base passions in the heart of the beholder. God sees that the ruin of the character is frequently preceded by the indulgence of pride and vanity in dress. He sees that the costly apparel stifles the desire to do good. CH 602.1
The more means persons expend in dress, the less they can have to feed the hungry and clothe the naked; and the streams of beneficence, which should be constantly flowing, are dried up. Every dollar saved by denying one's self of useless ornaments may be given to the needy, or may be placed in the Lord's treasury to sustain the gospel, to send missionaries to foreign countries, to multiply publications to carry rays of light to souls in the darkness of error. Every dollar used unnecessarily deprives the spender of a precious opportunity to do good.... CH 602.2
When you place a useless or extravagant article of clothing upon your person, you are withholding from the naked. When you spread your tables with a needless variety of costly food, you are neglecting to feed the hungry. How stands your record, professed Christian? Do not, I beseech you, lay out in foolish and hurtful indulgences that which God requires in His treasury, and the portion which should be given to the poor. Let us not clothe ourselves with costly apparel, but, like women professing godliness, with good works. Let not the cry of the widow and the fatherless go up to Heaven against us. Let not the blood of souls be found on our garments. Let not precious probationary time be squandered in cherishing pride of heart. Are there no poor to be visited? no dim eyes for whom you can read the word of God? no desponding, discouraged ones that need your words of comfort and your prayers? ... CH 602.3
Do not, my sisters, trifle longer with your own souls and with God. I have been shown that the main cause of your backsliding is your love of dress. This leads to the neglect of grave responsibilities, and you find yourselves with scarcely a spark of the love of God in your hearts. Without delay renounce the cause of your backsliding, because it is sin against your own soul and against God. Be not hardened by the deceitfulness of sin. CH 603.1

As a people, we are looked upon as peculiar. Our position and faith distinguish us from every other denomination. If we are in life and character no better than the world, they will point the finger of scorn at us and say, “These are Seventh-day Adventists.” “We have here a sample of the people who keep the seventh day for Sunday.” The stigma which should be rightfully attached to such a class is thus placed upon all who are conscientiously keeping the seventh day. Oh, how much better it would be if such a class would not make any pretension to obey the truth!—Testimonies for the Church 5:138 (1882). CH 603.2
