For a Christian , ignoring the confession , it has high potential to be pure blasphemy. For a not Christian, I suppose, it can be bizarre and absurd. I saw in the last scenes not as a film/play about Christianity and its message, not as a film about bigotism but as a story about teaching as refuge against life. Diane Keaton gives a splendid portrait of profound loneliness, need of power in absolute forms, about isolation in herself of a sister- obvious, Mary ignatius is a sister, not a nun and a precise indictment against sins, cruel mistakes of Romano - Catholic Church. It is not a black comedy, but good occasion to reflection. About soulless faith , about refuges and real meaning of education. A not comfortable film about forms of moral blindness .
