The unity of God, as one individual person, is denoted throughout the Bible by the almost constant use of singular pronouns, whenever any thought, action, attribute, or condition, is ascribed to the Supreme Being. In all languages the personal pronouns of the singular number are understood to apply only to one person.

Thus, if I were writing a letter, by employing the pronouns of the first person and singular number, I, Me, My, I should confine my assertions to myself as one individual person. By using the pronouns of the second person and singular number, Thou, Thee, Thy, I should indicate that my assertions were addressed to my correspondent as one individual person. By introducing the pronouns of the third person and singular number, He, Him, His, I should denote that it was one person only I was speaking of. If on the contrary, I were writing a letter in conjunction with any other intelligent being, we should use the pronouns We, Us, Our; and if I were writing anything of more than one person, I should say They, Them, Their. Such being the universal application of pronouns, it is evident, not only to those who have studied Greek and Hebrew, but to all who know the use and meaning of human speech, that throughout the whole Bible God is almost uniformly mentioned as one Person, this being implied in the almost constant use of singular pronouns.

The doctrine of the Unity of God is implied in every passage in which the personal pronouns of the singular number are used to denote the Supreme, Deity…. Thousands and tens of thousands of passages imply, by the use of the singular pronouns, that God is one person….
