I hear differing things. Realize it probably differs by diocese.
It might differ; yet, the
Program of Priestly Formation has pretty definite standards.
If someone already has an MA in theology and can speak a few languages, how long does it take to become a priest?
Are you looking to become a diocesan priest? It might take just as long as if you didn’t have that degree. After all, there are four pillars of formation, and intellectual formation is just one of them. Nevertheless, the formation program for a person who’s already done quite a bit of academic work might look somewhat different than the program of a person who has not.
Expect to spend some time in minor seminary (two years, but maybe a little less). I’d expect that, if you have an MA in Theology, you’ve already done substantial work in philosophy? If not, you’ll shore up your philosophy education in minor seminary. In addition, of course, you’ll enter a program of formation that will allow you to discern a vocation while working on the other three pillars.
Following that experience, expect four years in a major seminary. There, you might work on a different degree (whether in theology or otherwise). In addition, you’ll likely have opportunities to take on an assignment as a hospital chaplain, be assigned to a parish, and do work for a year as a deacon.
If you’re looking to enter into consecrated life, the timeframe will be different. You’d have to enter into their normal process, starting as a postulant and progressing normally. At the discretion of your superior, you might have the opportunity to enter into formation for the priesthood.
Talk to a vocations director in the diocese or community in which you’re interested. My advice isn’t to walk in there asking, “how much time can I shave off the process?” That never plays well. Rather, recognize that the time you spend in discernment and formation will pay handsome dividends in forming you for the vocation that God wishes you to embrace…
