I was at first surprised by this Damiano Damiani feature, after he has not used us with such topics, about Christianity. But if you analyse closely this story, you'll notice that there are some points in common with his other films concerning mafia: the quest of one man for a truth, a mystery to find everything about. Instead of the mafia, it is the truth about Jesus Christ. We also find here is pessimism, as we had in his crime movies. I am amazed by this feature, with Keith Carradine as Franco Nero was in the mafia films. I don't understand why it is not better widely known.
A rare gem for me. That's my own opinion.
