Quo vadis as a Latin phrase is usually rendered “where are you going?” But the verb has the sense “rushing to.” And the phrase emphasizes the end point, not the motion. Am I agitated, distracted, working frenetically, or putting off work? Whatever I am doing: the end of all my activity, what is it? The novel suggests: If I am not putting away everything else to move quickly towards Christ, I am going away from him.
