The Church and the Land: A Practical Symposium
A Practical Symposium
The Church and the Land: A Practical Symposium
October 3, 2026
The Christian tradition has long recognized a deep, if mysterious, connection between the worship of God and the work of the land, a connection which goes all the way back to the beginning of creation: "The Lord God put the man and put him in the garden of Eden to till it and keep it" (Gen. 2:15). Join us at the Catholic Ecology Center for an afternoon of festive gathering, practical workshops, and a keynote address devoted to exploring these two intertwined aspects of the human vocation.

Our mission

The St. Irenaeus Institute exists to make the Catholic intellectual tradition a vital part of the Church and the university in the greater Milwaukee area. Under the patronage of St. Irenaeus, the early patristic expression of that tradition animates our work even as we reflect upon the entire intellectual patrimony of the Church, from theology and philosophy, to the arts and sciences. We serve students, scholars, priests, and lay Catholics throughout the Archdiocese of Milwaukee.

First, please pray for our labors, that they bring many yields and fulfill God’s will. Please also consider making a one-time or recurring donation to the St. Irenaeus Institute. Without your generous gifts, our programs would not be possible; our unique efforts revitalize intellectual life, serving the city of Milwaukee from the heart of the Church, would cease.
