If you are thinking there is the possibility of a vocation to become a priest, talk with your pastor or another priest that you may know. Then contact a vocational director for the diocese.
The directors are to help you sort out the call. If there is something there, they will help you to come to a decision to enter the seminary. It is within the seminary that the call is fully examined, and ultimately a choice is made whether you are being called to priesthood, or your calling is elsewhere.
How old do I have to be?
It is never too young to consider a religious vocation. However, to be formally accepted into the seminary program you have to have graduated from High School.
How old can I be?
"Late" or "Second" vocations are very common. Generally though, once above the age of 50 special consideration needs to be given due to the amount of schooling.
Do I have to change my life right away?
Nope. Do continue your life, your relationships, your job. However, if you are living a lifestyle that is not reflective of a Catholic you will want to begin to change the direction of your life at some point soon.
Can I be married or get married?
Men who wish to be priests forgo the sacrament of matrimony in order to serve the Lord and the community in a different way. Men who were married at one point, but are currently not, either due to the death of their spouse or have had their marriage officially annulled may enter the seminary and become ordained.
Do I pay for this?
The Diocese will assume financial responsibility for the theology and for college level education.
Do I get to select the seminary?
The Diocese will select the seminary that is appropriate for the seminarian.
Do I have to learn Latin?
Generally Latin is not taught as a required course in most seminaries in the United States. Rather, seminarians in the Diocese of Reno are expected to learn Spanish or in some cases English to the best of their abilities.
What kind of degree do I earn at the end?
Once theology is complete the usual degree earned is a Masters in Divinity (MDiv). There is also the possibility of earning an Pontifical Degree.
How do I know if I am being called as Diocesan or a Religious Priest?
That is part of the discernment process. What can help to decide is whether you feel called to a specific place. That might indicate a diocesan calling. Is there a calling to a particular charism, e.g. teaching, working with the poor, missionary work? Then there may be a calling to a religious community.
