168. To say three Persons and one God is contradictory, for the term "person" involves something distinct and different from another. The distinction and the difference, also, is itself laid down in the doctrine of the church; and because the distinction differs among the persons, it follows that each is a separate God from another; and if separate, it follows that there are three Gods. That the substance or essence makes one God therefrom, this falls within the idea of no one, when the essence or substance is itself distinguished by the attributes of the one not proper to the other; for so one is worshiped for this attribute and another for that.
