Giles Corey embodies the effect of theocracy in a couple of ways. The first way is that he represents how the Salem theocracy featured an inability to effectively address the voice of dissent. Corey represents how the government of theocracy features fundamental limitations in its inability to accept the premises of free speech. Corey's stance to the theocratic court of Danforth and Hathorne represents this. He wishes to strike a notion of individual freedom, something that flies in the face of theocratic government. Corey represents the effects of theocracy in how his position, entirely reasonable, is deemed the opposite of it. Theocracy in Salem is one in which compliance is absolute. In doing so, in the face of the tenets of how compliance is absolute, Corey reflects how the effect of theocracy is a limited one. At the same time, Corey's refusal to back down from his own position and the suffering he endures because of it is reflective of how Salem's theocratic ways are limited and challenging, an element that helps to spell its own doom by the end of the narrative.
Salem is a theocracy, where all the laws are governed by God and people represent God. In Salem, in 1692, the inhabitants lived in a theocracy. Giles Corey's death is a direct result of the corruption caused by the theocratic society of Salem.
