A newspaper article I read some time ago referred, as I recall, to psychology as a popular "religion" today. For some people, if psychology has taken the place of religion in their lives, perhaps the human mind is like its god.
This observation led me to consider in a new way the First Commandment, which God gave Moses for His people to live by: "Thou shalt have no other gods before me." Ex. 20:3. That commandment might also be stated this way: "Thou shalt have no other Mind but Me." In reality, there is one intelligence, one source of wisdom—the divine, infinite Mind. This is the only Mind one can truly have. The so-called human mind with its fears, hates, and uncertainties is not a power or intelligence to hurt or heal.
Science and Health by Mary Baker Eddy asks the question "What is Mind?" and answers: "Mind is God. The exterminator of error is the great truth that God, good, is the only Mind, and that the supposititious opposite of infinite Mind—called devil or evil—is not Mind, is not Truth, but error, without intelligence or reality. There can be but one Mind, because there is but one God; and if mortals claimed no other Mind and accepted no other, sin would be unknown. We can have but one Mind, if that one is infinite." Science and Health, p. 469.
