From the nature of intelligent creatures, and their relations to one another and to material objects, the execution of this undertaking required a course of external and visible facts connected both with his and their agency. They were to be instructed both in respect to themselves and to him; and as the visibility of their persons and acts was necessary to their instruction concerning one another, the visibility of his person and acts was necessary on the same account. It is evident that the Mediator has, officially, relations to the holy angels, not only as their Creator, but in other respects. They are required to worship him in that character, _i. e._, in the character in which he came into the world. Heb. i. 6. They are employed in executing the measures of his mediatorial administration. Heb. i. 14. They attended his person on the occasion of his advent, his temptation, his sufferings and resurrection, and join his people in their songs and praises, in view of his final triumph and exaltation. As Mediator, he is invested with all power in heaven and earth. All judgment is committed to him in that capacity, "because he is the Son of man," the official Person; and we must conclude that his official work comprises all Divine operations relating to creatures. In the phraseology both of the Old and New Testaments, where God is represented as acting or speaking, the expression in most cases is such as would occur were there no distinction of persons in the Godhead, unless we understand, wherever the text does not in terms or in the nature of the subject indicate another reference, that the appellations, Elohim, Jehovah, Messenger Jehovah, &c., are employed to designate the Mediator, personally and officially. But so understood, he stands forth the external representative, the visible image, the outward manifestation, the official agent, the messenger of the Father, and as such reveals Him; and by the mission and coöperation of the Holy Spirit in the work of redemption, that Divine Person is made known. The entire scheme respecting the creation and government of creatures being in the counsels of eternity assigned to the second Person, as the official agent and messenger delegated and sent of the Father, it appertained to him to make known to creatures all that they are to know of the being and perfections of the One God and the distinction of persons in the Godhead. Accordingly the Deity, without any special indication of personal or official relations, is often referred to under the terms Jehovah and Elohim, where the object required only a distinction of divine from creature attributes or agency. In this way, in one class of passages, God is said to do the same things which in another class are expressly ascribed to the Messenger Jehovah, the Christ, the Word.
