Religion: In the movie "Amen" Did Riccardo Fontana the priest, realized at the end that he was in the wrong religion?

You do realize little lady that Fontana was not a priest and this movie was filmed in a doubtful way. :P

Movie Fontana

Riccardo Fontana never doubted the Christian faith. It was the Church officials not acting accordingly that he was disappointed at. Riccardo Fontana s joining the Jews at concentration camp is his one way of saying that "This is what true Christians do... loving their sisters and brothers regardless of race, culture or religion - being in solidarity with them. True Christians love in deeds, not only words."

You are really asking a question that very very few people are even aware of. Did you know there are at least 3 movies named "Adam"? And your movie is still quite old dating back to 2002. But here is a quote:

"While the character of Kurt Gerstein is historical, the character of the young priest is fictional as well as the plot".

You missed the point of the question. But you get best answer as a pay back. :P
