Selections from the Writings of Kierkegaard

No. And why not? Because one cannot "know" anything at all about "Christ"; for he is the paradox, the object of faith, and exists only for faith. But all historic information is communication of "knowledge." Therefore one cannot learn anything about Christ from history. For whether now one learn little or much about him, it will not represent what he was in reality. Hence one learns something else about him than what is strictly true, and therefore learns nothing about him, or gets to know something wrong about him; that is, one is deceived. History makes Christ look different from what he looked in truth, and thus one learns much from history about—Christ? No, not about Christ; because about him nothing can be "known," he can only be believed.
