Since writing this work, the author has read the treatise of Dr. Isaac Watts, entitled, "The Glory of Christ as God-Man," in which he describes the visible appearances of Christ before his incarnation, inquires into the extensive powers of his human nature in its present glorified state, and endeavors to explain and illustrate the Scriptures which relate to those appearances, and to the Person who under various divine names and official designations visibly appeared, by supposing that the human soul of Christ was created prior to the creation of the world, and thenceforth, being united to the Second Person of the Godhead, appeared and acted, visibly and otherwise, in all that related to this world. There being no question but that the mediatorial Person created the world, appeared visibly, and conducted the administration of the Old Testament dispensations, there is, as might be anticipated, a degree of plausibility in the reasonings and illustrations of this venerated author. But many grave and unanswerable objections to his peculiar views present themselves. It is not perceived that the supposition of the preëxistence of the human soul of Christ is either sustained by the Scriptures, or has in any respect, as a means of explanation, any advantage as compared with the view taken in this work, viz: that, pursuant to a covenant between the Persons of the Godhead, the Second Person assumed the official character and relations which are peculiar to him as Mediator; those, viz: in which he executed the works of creation and providence, and manifested himself under various Divine names and official designations, as Jehovah, Elohim, the Messenger, the Messiah; the official personal actor and revealer. To his Person in this official character and agency the human nature was in due time united, so as to include two natures in his one Person. But since the delegated official Person, into union with which the human nature was taken, preëxisted, and as a Person was the same before as after the incarnation, the acts of that Person in the delegated official character and relations above referred to, were to the same effect, and involved essentially the same conditions before as after the advent. Since he undoubtedly acted as Mediator in the ancient dispensations, we must, in reference to his agency then, ascribe to him what peculiarly constituted and ever preëminently distinguishes that character, viz: its being the delegated official character of a Divine Person. Regarded in that light, there seems no more difficulty in ascribing visible appearances and other acts suitable to his office in his relations to men, prior to the assumption of human nature into union with his Person, than after that union. The relations of his Person, in his delegated official character, to creatures and material things, were the result, not of the incarnation, nor of any occurrence after the commencement of
