Keeping the Faith (2000) on Netflix

A love triangle between three friends. Rabbi Jake Schram and Father Brian Finn, two friends, are out to update their religions and draw in more worshipers. With the arrival of Anna Reilly, an old childhood friend of the two, the men's lives are thrown a curve ball. Anna has become a stunning beauty with a lot of spunk and ambition, and both of them want her. A major road block to Anna for both men is their religion. Jake is up for a head position at his synagogue and taking on a non-Jewish partner is frowned upon, besides the fact that his mother disowned his brother for marrying a non-Jewish woman. Brian has given a vow of celibacy to become a priest.
