What if someone goes to the seminary and then decides he doesn’t want to become a priest?
Seminarians are not people who have everything figured out. In fact what they are doing is seeking God’s will, by putting themselves in a setting where they can truly discern God’s will. Spiritual direction and seminary formation are important components of this. If an individual decides priesthood is not for him, he is certainly most free to leave. Seminary is not a prison! The job of seminary is not to try to brainwash people or convince them that they should become priests, but rather to help them to truly discover God’s will and, if that is priesthood, to make them the best possible priests. Sometimes people are afraid to give it a try for fear of failure. There is no way to avoid risks in life. Everyone who goes to medical or law school doesn’t necessarily stay. I guess the old saying is true: Nothing ventured, nothing gained!
