In his various letters to the churches the Apostle Paul had much to say about his brethren being "of one mind." To the Romans he wrote, "Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus: that ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ."
Interpreted from the human standpoint, to "be of one mind" simply means that many having differing views have so concurred on a given subject that they have come to an agreement of opinion. From the viewpoint of the understanding that Christian Science gives of the one infinite Mind, God, who is reflected by man, we find that in reality all men are "of one mind," for in the expression of the one Mind there can be neither minds many nor conflicting, erroneous conclusions. Mrs. Eddy defines "Mind," in part, as "the only I, or Us; the only Spirit, Soul, divine Principle, substance, Life, Truth, Love; the one God; not that which is in man, but the divine Principle, or God, of whom man is the full and perfect expression" (Science and Health with Key to the Scriptures, p.591). She also explains the impossibility of there being other minds than the one which is God, when she says (ibid., p.469), "Mind is God," and adds, "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."
But we know too well that mortals have claimed and accepted another sense of mind than the one divine Mind; and this so-called mind is the very antipode of the one infinite Mind. It is a finite sense of mind, and all of its concepts are material and finite, subject to discord, inharmony, accident, disease, death, disintegration. Moreover, each mortal is supposed to possess a separate mind of his own. Since the one infinite God is Mind, how can there be in reality another mind, which is mortal?
