“Christ died for our sins,” said the primitive disciples, “according to the Scriptures; he was buried; he has been raised on the third day according to the Scriptures.” From the beginning, the Christian gospel, as indeed the name “gospel” or “good news” implies, consisted in an account of something that had happened. And from the beginning, the meaning of the happening was set forth; and when the meaning of the happening was set forth then there was Christian doctrine. “Christ died”–that is history; “Christ died for our sins”–that is doctrine. Without these two elements, joined in an absolutely indissoluble union, there is no Christianity.
It is perfectly clear, then, that the first Christian missionaries . . . did not say: “Jesus of Nazareth lived a wonderful life of filial piety, and we call upon you our hearers to yield yourselves, as we have done, to the spell of that life.” . . . [T]hey said nothing of the kind. . . . The great weapon with which the disciples of Jesus set out to conquer the world was not a mere comprehension of eternal principles; it was a historical message, an account of something that had recently happened, it was the message, “He is risen”.
