University of Saint Mary of the Lake | Mundelein, Illinois
Drive about an hour north of downtown Chicago and you will come to a lake, and around that lake a campus of red brick and white columns that looks less like a graduate school and more like a small colonial town that somehow ended up in the Illinois woods. This is Mundelein Seminary, the seminary and school of theology for the Archdiocese of Chicago, and it is one of the most significant places in American Catholic life that most people have never heard of.
It is also, by our reckoning, one of the strongest Catholic seminaries in the country. So we wanted to tell its story.
A school older than it looks
Mundelein feels historic because it is. The University of Saint Mary of the Lake was chartered by the state of Illinois in 1844, making it the first institution of higher education in Chicago. That first version of the school did not last. The university suspended operations in 1866 during hard financial times, and the original building was lost in the Great Chicago Fire of 1871.
The school as we know it today was really the work of one man. In the early 1920s, Cardinal George Mundelein, the Archbishop of Chicago, wanted more priests and a proper place to form them. He revived the old charter, secured a major gift from Edward Hines, and built a new campus on land north of the city. The seminary opened its doors again in 1921 and has been in continuous operation ever since. The surrounding village, then known as Area, was later renamed Mundelein in the cardinal's honor, which is why both the seminary and the village carry his name today.
The campus he built is worth describing. It sits on more than 600 acres around Saint Mary's Lake, laid out in careful symmetry and centered on a chapel. The style is neo-Georgian, all brick and columns and quiet order, and the effect is deliberate. Cardinal Mundelein wanted a place that felt rooted in something older than itself. He got one.
The first of its kind in America
Here is the detail that sets Mundelein apart from almost every other seminary in the United States.
In 1929, Cardinal Mundelein obtained a grant from Rome establishing a Pontifical Faculty of Theology and allowing the school to confer the ecclesiastical degrees of the Catholic Church: the baccalaureate, licentiate, and doctorate in theology. In 1934, that grant was made permanent, making Mundelein the first American institution to become a Pontifical Theological Faculty under the Church's then-new system.
That word, pontifical, is not decoration. It means the faculty has been established by the Holy See and is authorized to confer ecclesiastical degrees recognized throughout the Catholic Church. Only a handful of schools in North America hold this status. Mundelein was the first in the United States and remains one of just seven Pontifical Faculties of Theology in North America. For a Catholic student, and especially for a man discerning the priesthood, that lineage matters. It places Mundelein within a small group of North American institutions entrusted with offering the Church's own ecclesiastical degrees in theology.
The seminary is also accredited by the Association of Theological Schools, the same body that accredits many graduate theological schools across Christian traditions. Its accreditation was most recently reaffirmed in 2022 and extends through 2032.
What formation looks like here
Mundelein is a full-time, residential seminary, and that is central to what it does. Priestly formation is not treated as a set of classes you attend and then go home. It is a way of living, and the men who come here to discern the priesthood live it together on that lakeside campus, following the norms the United States bishops have established for forming priests.
The academic work is rigorous, but the school is just as attentive to the parts of formation that do not show up on a transcript. Its program includes the Tolton Teaching Parish Program, which places seminarians in parish communities, along with two full-time internships and an eight-week study pilgrimage to the Holy Land during the third year of theology. The idea running through all of it is that a parish priest needs more than knowledge. He needs to have prayed, to have served real people, and to have walked, in some literal sense, the ground the faith came from.
The faculty is among the largest of any seminary in the country. Many of its professors are recognized leaders in their fields, and some have served on pontifical academies and councils or with the International Theological Commission. Students come from the Archdiocese of Chicago and from dioceses and religious communities across the United States and abroad.
More than a seminary for priests
It would be easy to assume a place this focused on forming priests has little to offer anyone else. That is not the case.
Alongside the seminary, the university runs the School of Parish Leadership and Evangelization, which forms lay men and women, in both English and Spanish, for leadership and ministry in the life of the Church. The university also houses institutes and programs serving deacons, lay ministers, and clergy who are already ordained but continuing to learn.
Today, the University of Saint Mary of the Lake reports more than 1,000 lay students alongside roughly 100 seminarians. Its conference center welcomes approximately 25,000 to 35,000 guests each year.
So while the heart of Mundelein is the formation of parish priests, the life of the place is broader than that. It is a school for the whole Church, laypeople included.
Why it made our list
When we selected the best Catholic seminaries, Mundelein stood out, and the reasons are not complicated. It is one of the largest and most prominent Catholic priesthood-formation programs in the United States. It holds pontifical status, which only a few schools anywhere in North America can claim. Its faculty is deep and widely respected. Its formation is thorough in a way that goes well beyond the classroom. And it does all of this on a campus built, more than a century ago, to make exactly this kind of work possible.
In 2021, the school marked its centennial, a hundred years since Cardinal Mundelein reopened its doors. More than a century after that revival, Mundelein remains an important institution in American Catholic theological education and priestly formation.
