On January 25, the college hosted Dr. Anthony Andres to give the 2024 Thomas Aquinas Lecture. The annual Aquinas Lecture is an opportunity for the Christendom College community to benefit from the scholarship and wisdom of noted thinkers in the tradition of St. Thomas Aquinas.

On January 27th, 2020 Christendom College hosted Dr. Daria Spezzano to give a talk for the 2020 Thomas Aquinas Lecture. Dr. Spezzano demonstrated the elements of eros in St. Thomas Aquinas's understanding of the Eucharist. Thomas Aquinas also applied elements of eros more broadly to his theology of charity in a distinctly Dominican way.

Dr. Daria Spezzano is an associate professor of Theology at Providence College in Providence Rhode Island. She received her Ph.D in Theology from the University of Notre Dame and her Masters of Liturgical Studies from the Liturgical Institute. She is the author of The Glory of God's Grace: Deification According to St. Thomas Aquinas. Her writings have been published in Nova et Vetera, Cistercian Studies, and Antiphon.

Fr. Dominic Langevin, O.P., delivered the 2019 St. Thomas Aquinas Lecture on February 4, lecturing on the importance of the moral and sacramental life, without which there can be no eternal life. He further discussed the Thomistic teaching on the complementary of the moral and sacramental life.
