How does Lefty change over the course of the novel, Wheat That Springeth Green?

Lefty Beeman is a simple easy-going priest. He’s the kind of guy to have a beer with—which Joe does quite often. Lefty is no wannabe saint, no ruthlessly opportunistic administrator, he is (as his name suggests) a man, a good guy, a nice guy who is Joe’s closest (and really only) friend. He is extraordinarily ordinary, remarkably unremarkable: he is funny without wit, charming without calculation, and honest without irony. He is a competent priest, but he never finds his way to spiritual purity. He is inept with routine pastoral duties (before Joe gets his first pastoral appointment, Lefty has already been appointed to and then removed from two parishes). When he and Joe thwart the liquor store holdup, Lefty undergoes a change of heart—not soul--and tells Joe he is ready now to commit his energies to the rigors of the priesthood. As the novel closes, Lefty assumes the pastoral position at Joe’s old parish.
