Which are Stephen spiritual dilemmas?

Stephen finds it difficult to maintain a state of saintly serenity. If anything, his various methods of self-discipline make him more irritable. He does not grow more charitable or kind to his family or his peers. He thinks of the various clergymen he knows, and how they seem just as subject to human pettiness and irritability as everyone else; he also has some doubts about the rather rigid Catholic compartmentalization of different virtues and wisdoms.
