Describe symbolism in Dancing at Lughnasa by Brian Friel

Jack Mundy (Uncle Jack) begins the novel as a symbol of Catholic righteousness and order. When Jack went to Uganda twenty years before the start of the novel, he was a Catholic priest, working as a missionary. He has recently returned from Ireland after being asked to leave his vocation as a result of his participation in non-Christian ceremonies and rituals. Upon his return, he is seen as a symbol paganism.... abandonment..... a traitor to his beliefs, and he is rejected by his community.
