Karl Barth, CD IV/1, 290 =KD IV/1, 319. According to Barth, this is the real question that "Lessing's [famous] question concerning the relationship between the contingent truths of history and the necessary truths of reason", or "the gaping and wide chasm which I cannot cross" (287), only culpably avoids (since the difficulty "has in fact been removed"):
And now we have to ask whether our whole concern about our temporal distance from Jesus Christ, our indirect relationship to Him, is not a genuine problem only in the sense that it represents a genuine movement of flight from this encounter. Are we not putting up a technical difficulty, knowing all the time that this difficulty is not so great that it cannot be removed, that it has in fact been removed?(290-291). Etc.
