Now that adulthood has arrived there is a branching of the path forward. There is becoming a nun or a priest or a person committed to another in marriage. 

Both paths are similar.

They are both forms of marriage.

One is to a partner for life and the other as a partner to god.

Most everyone becoming a dedicate person to god usually states it is a 'calling.' A longing, if you will.

There is a dear friend that once believed he was destined to be a priest. He went to the church to receive the sacrament for the priesthood, but, he left. He stated, there was a common ground most of the other men experienced that he did not. They all spoke of their experience before they became a priest and it was indeed a calling. An emotional experience to move them to the priesthood. He stated for as much as he loved god, he never had the experience that all the others did. At that point, he thought he was there for his love of god and not god's love of him.

He never married.
