What are some of the questions Antonio is unsure of as he rides in Uncle Pedro's truck?

Antonio thinks about and questions many things while riding in Uncle Pedro's truck. He is uncertain; he questions morality, faith, and destiny. He ponders Ultima's gifts, questioning their origin... are they holy, or do they defy the church? Antonio also thinks about his own future, questioning whether or not he follow his mother's desire to see him become a priest, or whether he follow his father's dream that he become a vaquero.
