"Behold, I Paul say unto you, that if ye be circumcised Christ shall profit you nothing." Gal. 5:2. In the memorable letter of the apostles and elders to the Gentile churches, Acts 15:23-29, they say, "It seemed good to the Holy Ghost and to us, to lay upon you no greater burden than these necessary things." "To the Holy Ghost and to us" can mean only, to us under the guidance of the Holy Ghost. Besides such explicit assertions as the above, there is a tone of authority running through the apostolic writings which can be explained only from their claim to speak with divine authority. They assert the weightiest truths and make the weightiest revelations concerning the future, as men who know that they have a right to be implicitly believed and obeyed. What majesty of authority, for example, shines through Paul's discussion of the doctrine of the resurrection, 1 Cor., ch. 15, where he announces truths that lie wholly beyond the ken of human reason. "Behold," says he, "I show you a mystery; we shall not all sleep, but we shall all be changed," as one who has perfect assurance that he speaks from God. The same tone of certainty runs through all the remarks which the apostle John interweaves into his gospel, as well as through his epistles, and through the other apostolic writings. To sum up in a single sentence what has been said respecting the apostles: When we consider the strong presumption, arising from the necessity of the case, that they must have been divinely qualified to teach and write without error, the explicit promises of Christ that they should be thus qualified, and their explicit claims under these promises, we have full evidence that they wrote, as well as spoke, under the inspiration of the Holy Ghost, and consequently that their writings are of divine authority.
