“THERE IS ONE GOD, AND ONE MEDIATOR BETWEEN GOD AND MEN, THE MAN CHRIST JESUS.”—1 _Tim._ ii. 5. The passage I have read suggests the subject of my lecture, the position in which we stand to our opponents will suggest the tendency of the commentary. The text announces the two great truths on which our entire system of Christianity is based, and ours in all essential points, we think, coincides with simple, with evangelical Christianity. The truths propounded in the text are, the Unity of God, and the Unity of Christ.—A unity in each case absolute and perfect, without division of nature or distinction of person. We believe that God is one,—that he is one being, one mind, one person, one agent. And this belief, and no other, we can deduce from the works of creation, and the teachings of the Scriptures. That God is one universally and absolutely, we have impressed upon us from the order of creation; that he is great, we learn from the magnitude of his works; and that he is good, we learn from their blessedness and beauty. This sublime truth is illustrated in every region of existence, so far as we know it, and every illustration is an argument. It is written on the broad and immortal heavens in characters of glory and light; it is manifested in that mighty law which binds atom to atom into a world, and world to world in a system, and system to system, until from that wonderful universe which science can traverse, we arise to him, whom no knowledge can fathom, whom no limits can bound, and in contemplating whom science must give place to faith.
