Halloween appears among the pagan holidays that professing Christian churches hypocritically celebrate despite their claims to represent God and Christ. It is identified as the most demonic holiday of the year, one in which children are dressed up in ungodly costumes and pagan jack o'lanterns are sold for profit. Dark, demonic activities are said to clearly permeate this observance, and it is noted as the holiday on which people spend the most money of all, being described as Satan's most cherished day. This point about costumes and Halloween is raised within a larger discussion of the fifth sinful reason for God's judgment against Israel in Hosea 8: the construction of false altars. Israel had multiplied altars beyond the one God had appointed, introducing ceremonial rituals and traditions of men into what was claimed to be worship of the true God. The modern equivalent is identified as churches, altars, and Christian symbols that claim to represent God and Christ but lack scriptural authorization, instead following human tradition. Such symbols, said to have pagan origins, include the crucifix, the fish, Christmas trees, yule logs, rabbits, eggs, and the sun. Alongside Halloween, Easter and Christmas are named as further examples of this hypocrisy—Easter tied to ancient sun worship through sunrise services reminiscent of pagan praise of Ishtar, and Christmas linked to the ancient festivals of Brumalia and Saturnalia, which celebrated the rebirth of the sun yet were renamed after Jesus Christ. The broader point drawn from this pattern is that Israel was guilty of religious hypocrisy and apostasy then, and the same charge applies today, since these observances—including the wearing of costumes at Halloween—are justified by claiming a "Christian perspective" even though they stem from pagan origins. This excuse is presented as unacceptable before God, who does not overlook such deceit. These practices are tied back to the root sin identified in Hosea 8:14, that Israel "forgot" God—not through intellectual denial, but through neglect, replacing true worship with humanly devised rituals and symbols. The mention of Halloween costumes thus serves as a contemporary illustration of how nations claiming to honor God simultaneously incorporate practices of pagan origin, repeating the very pattern of hypocrisy that brought God's judgment upon ancient Israel.

The wearing of costumes stands at the heart of Halloween's appeal, functioning together with alcohol consumption as the year's biggest escape from reality. Rather than genuine fascination with ghouls, spirits, or the otherworldly theme of the holiday, the true attraction lies in the opportunity costumes provide to disguise oneself and pretend to be something one is not. Most people do not actually believe in demonic or angelic spirits enough to treat Halloween as a celebration of them; instead, the donning of costumes allows participants to shed the constraints of their normal identity and indulge in behavior otherwise held in check. This practice traces back to the ancient Celtic festival of Samhain, observed around November 1, from which All Saints' Day and All Hallows Eve derive. The Celts believed this period existed in a kind of "no-time," belonging neither to the old year nor the new, during which normal laws, order, and customs were suspended for three days of merriment. Within this suspended reality, costumes played a central role in the reversal of social roles: the fool held court as the wise man, the baseborn acted as the noble, the servant became the master, and women dressed as men while men dressed as women. This disguising of one's true identity was part of a broader pattern of total abandon, revelry, feasting, drinking, and pretending to be something one was not, as farmers even released their livestock to roam free and some entered homes through windows rather than doors. Modern Halloween is described as a tame descendant of this ancient chaos time, yet its underlying function remains the same: costumes and revelry allow celebrants to escape mundane, stressful lives and take a walk on the wild side, temporarily suspending laws, customs, and moral restraint. While many consider this merely blowing off steam or having a good time, such self-indulgence constitutes sin. Rather than following the biblical call to come out of a world that conducts its affairs apart from God, celebrants who use costumes as a means of escaping into indulgence compound their troubles by adding sin and its destructive consequences to already stressful lives. This stands in direct contrast to the transformed life to which believers are called—one in which former corrupt, lustful conduct is put off and replaced with new habits reflecting the righteous and holy life of Jesus Christ. Rather than using disguise to escape into darkness, believers are instructed to walk as children of light, proving what is acceptable to the Lord, having no fellowship with the unfruitful works of darkness, and instead exposing them. The call is to walk circumspectly, not as fools but as wise, redeeming the time because the days are evil—a direct counterpoint to the costumed self-indulgence and chaos that Halloween, in its historical and modern forms, represents.

Costumes occupy a central place in the modern celebration of Halloween, forming part of a larger pattern of practices traced back to pagan roots and shown to be incompatible with a Christian's relationship with God. Statistically, roughly 65-70% of adults participate in Halloween activities, which include wearing a costume, and this participation reflects a broader cultural shift in which Halloween has grown to become second only to Christmas in retail sales, with billions spent annually on costumes, candy, decorations, and party favors. Adults increasingly find in Halloween an opportunity to shed their inhibitions behind a mask and costume, treating the holiday as a socially sanctioned occasion for behavior they would not otherwise display, which has contributed to Halloween's growing popularity among grown men and women rather than merely children. The custom of wearing costumes and disguises did not originate as innocent play but has clear roots in the Celtic festival of Samhain, observed over three days around November 1. The Celts regarded this period as a kind of "no time," a transitional interval when the normal boundary between the physical and spiritual worlds was believed to relax, allowing spirits to cross over. During this time, ordinary social order and law were suspended entirely; the fool became king and the king became the fool, men dressed as women and women as men, and people took on entirely different personas, dressing in disguise and acting out roles contrary to their everyday identity. This total abandonment of order was marked by revelry, drinking, dares, and lawbreaking, amounting to a period of deliberate chaos in which disguise served to mask normal identity so that the customary rules of conduct could be set aside. This background exposes the seemingly harmless practice of children dressed in "cute costumes" shouting for candy at neighbors' doors as something with far darker origins than professing Christians often assume. Trick-or-treating itself, closely tied to costuming, is identified as a modern survival of the Celtic practice of appeasing wandering spirits with food and treats to prevent them from playing tricks or placing curses on households; children, whether they realize it or not, act out the role of spirits who will bring misfortune upon those who fail to pay tribute in candy. Thus, the costume is not a neutral element of children's fun but functions as a direct continuation of a pagan custom rooted in fear of the spirit world and the need to placate it. Taken together, these details reinforce the broader argument that Halloween, despite its outward appearance of harmless festivity, is fundamentally rooted in pagan belief regarding the dead and the spirit world, practices which the Bible consistently condemns as idolatrous and abominable. The wearing of costumes, whether by children trick-or-treating or by adults seeking to shed normal restraint, is bound up with the ancient Celtic pattern of disguising identity during a time when law and order were suspended and spirits were thought to roam freely. Recognizing this origin removes any justification for viewing costumes and related Halloween customs as innocuous, since they descend directly from practices God's word identifies as futile, worthless, and detestable to Him.
