Joyce's idea regarding religion is shown in his stories. He slaps at the extremities of the religion at his time. He briongs out the unwanted influence of the religion in his stories. For example, in his story The Boarding House, he shows how Doran was morally paralyzed due to the religious forces. (Priest magnified the sin, he asked for every ridiculous detail of the affair)
"There's no heresy or ni philosophy which is so abhorrent to the church as a human being."
