Rebutting Necessitarian Universalism: Three Thomistic Arguments – Prof. Mats Wahlberg

Prof. Mats Wahlberg argues that “necessitarian universalism”—the claim that hell is metaphysically impossible and that God must save all rational creatures—is incompatible with core Christian metaphysical commitments, and he develops three Thomistic arguments to show that the possibility of eternal damnation follows from God’s wisdom, respect for created natures, and desire for truly free self-gift.This lecture was given on September 6th, 2025, at Dominican House of Studies.Through your gift to the Thomistic Institute, you will send the best scholars in the Catholic Intellectual Tradition directly to college campuses, bringing the light of Christ to students longing for answers. Thanks to a group of generous donors, every dollar you send up to $150,000 before December 31 will be matched.  This means that your gift will touch twice as many souls!To make your gift today, visit https://thomisticinstitute.org/donate-podcast For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speakers:Mats Wahlberg, Ph.D., is docent and associate professor of systematic theology, a member of the Academy of Catholic Theology, and a research fellow in the Discipline Group of Systematic Theology and Ecclesiology at the Faculty of Theology, Stellenbosch University, South Africa.

Prof. Thomas Osborne explains reprobation and the permission of sin in Thomas Aquinas as the asymmetrical counterpart to predestination, where God positively causes the grace and merits leading the elect to glory but only permits the sins of the reprobate without ever willing or causing moral evil, thus safeguarding both divine justice and human responsibility.​This lecture was given on September 6th, 2025, at Dominican House of Studies.Through your gift to the Thomistic Institute, you will send the best scholars in the Catholic Intellectual Tradition directly to college campuses, bringing the light of Christ to students longing for answers. Thanks to a group of generous donors, every dollar you send up to $150,000 before December 31 will be matched.  This means that your gift will touch twice as many souls!To make your gift today, visit https://thomisticinstitute.org/donate-podcast For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speakers:Thomas M.

Fr. Piotr Roszak shows how Thomas Aquinas interprets predestination through a deeply biblical lens, reading predestination as God’s merciful, Christ-centered plan to lead creation freely to a supernatural end and insisting that scriptural context is essential for avoiding deterministic distortions of the doctrine.This lecture was given on September 5th, 2025, at Dominican House of Studies.Through your gift to the Thomistic Institute, you will send the best scholars in the Catholic Intellectual Tradition directly to college campuses, bringing the light of Christ to students longing for answers. Thanks to a group of generous donors, every dollar you send up to $150,000 before December 31 will be matched.  This means that your gift will touch twice as many souls!To make your gift today, visit https://thomisticinstitute.org/donate-podcast For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speakers:Piotr Roszak is an adjunct professor of Fundamental Theology at Nicolaus Copernicus University in Torun, Poland; associated professor of Systematic Theology at University of Navarra, Pamplona, Spain, where he obtained his PhD in 2009.
