There are six names by which, in various parts of his epistles, St. Paul describes the commission in virtue of which he spent his life and finally poured forth his blood in preaching the Gospel. These six names are apostle, minister, doctor, steward, ambassador, and herald. Sometimes they are mentioned singly, sometimes they are blended with each other in a way which sheds light upon them reciprocally. He terms himself an ambassador, when he says, "for Christ, therefore, we are ambassadors, God as it were exhorting by us." And he beseeches his converts to pray for him "that speech may be given me that I may open my mouth with confidence, to make known the mystery of the Gospel, for which I am an ambassador in a chain."[31] He refers all his power back to God when he says, "Our sufficiency is from God, who also has made us fit ministers of the New Testament," for this word, the original of deacons, signifies here a ministry to God, not a service of men. The sufficiency was that God had accredited certain men to bear to their fellow-men a certain document, a new covenant. They stood in the relation of ministers to Him who appointed them; to those to whom they came they were the commissioned agents of a sovereign. He calls himself also a steward,[32] where he says, "Let a man so account of us as the servants of Christ, and the dispensers of the mysteries of God. Here now it is required in dispensers that a man be found faithful; but to me it is a very small thing to be judged by you, or by man's day,—but He that judgeth me is the Lord." And in another place he very remarkably joins together three terms which he applies to himself, while he specially connects them with the source and head of all power in that work of the dispensation which He became man to accomplish. St. Paul breaks into a sort of creed, which is like a summary of his whole message, in these most solemn words which he addresses to the archbishop whom he had himself set in the great see of Ephesus: "There is one God and one Mediator of God and men, the man Christ Jesus, who gave Himself a redemption for all, a testimony in due times. Whereunto I am appointed a herald and an apostle (I say the truth, I lie not), a doctor of the Gentiles, in faith and truth." And he joins the same three names together in another letter to the same Bishop, "The Gospel whereunto I am appointed a herald and an apostle and a doctor of the Gentiles."[33] The original word herald was rendered by preacher; and the term Apostle has become so fixed as the name of those to whom our Lord committed His Church in chief, that the lesson as to the source of the authority which it bears in its meaning of "the sent," has been impaired to many minds. A multitude of men preach in these days without any notion that a preacher is a man who bears a divine commission from a Sovereign to announce pardon to His people, and that a man who chooses himself for such a function is an impostor. Now what I wish to remark of
