Seminary – How Does a Man Become a Priest and How Long Does It Take? In a two birds, one stone scenario, here is some basic information on the timeline of formation of future priests. My hope is that it will fill out the bulletin information from previous weeks about our current priest to parish ratios, as well as shed light on the process by which priests are formed and encourage the young men of our parish to consider the call to priesthood and further encourage the parish to pray for vocations. ~ Fr. McC Major Seminary in the Archdiocese of Cincinnati currently has four years of academic classes and formation and one year of internship at a parish. At the end of Theology III (the 4th year), a man is ordained to the transitional diaconate. At the end of Theology IV (the 5th year), a man is ordained to the priesthood.
Below shows how the years of Seminary flow for a man entering formation at the College Seminary or at the Major Seminary in Pre-Theology.
