Con artist with a bible

I remember this movie where this con artist rolled into a small town and uses the bible and religion to get money out of people.
I remember a part where there was a small town church and a parish priest who actually believed him.
around the end of the movie, to the surprise of this con artist and everyone in town an old tree in the churchyard bloomed with lovely flowers that made the town a tourist attraction or something to that effect.
It’s not elmer gantry or paper moon or leap of faith. I think I remember seeing it in the 1990s..
