St .Thomas Aquinas’ Spiritual Exegesis of the Mass - Fr. John Saward

Fr. John Saward presents Aquinas's Summa III, q.83 as a "spiritual exegesis" of the Mass, showing how the Angelic Doctor reads the rites, words, and ceremonies of the Mass as signs that both signify and make present the saving mysteries of Christ's passion, grounded in the real presence and in the priest's acting in persona Christi.This lecture was given on May 18th, 2026, at University of Oxford.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-eventsAbout the Speaker:Fr.

I have found this ideal realized and sustained within the fraternal life of the Province of St. Joseph.”

Fr. John Mark Solitario explains the seven gifts of the Holy Spirit as stable infused dispositions that render the soul responsive to the Holy Spirit's promptings, completing the virtues by introducing a divine mode of acting, and shows that they are necessary for salvation and Christian perfection because human reason, even healed by grace, remains susceptible to folly and ignorance.This lecture was given on April 25th, 2026, at Dominican House of Studies.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-eventsAbout the Speaker:Fr.

Fr. Thomas Aquinas Pickett argues that "living your best priesthood" consists not in natural self-improvement but in the exercise of two infused virtues: charity, the friendship with God by which he communicates his beatitude to us and the fire of Christ's own priestly self-offering, and religion, the virtue of reverencing God and rendering him the worship that is his due.This lecture was given on March 28th, 2026, at St. Albert Priory.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speaker:Fr.

Prof. Bruce Marshall argues that the Mass is a truly propitiatory sacrifice in which Christ's once-for-all offering on the cross is made present (not repeated) and given into the hands of the Church to be offered by priest and people together, so that by their active participation, the lay faithful share in Christ's eternal priesthood and the work of our redemption.This lecture was given on March 28th, 2026, at St. Albert's Priory.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speaker:Bruce D.

Fr. Thomas Davenport corrects two misunderstandings of Aristotelian-Thomistic epistemology — the caricature that Aquinas relies on an intuition of essences and the oversimplification that the agent intellect automatically abstracts universals from phantasms — by recovering Aquinas's notion of experimentum, an ordered, pre-universal knowledge produced by the cogitative power's active collatio of particular intentions stored in memory, which prepares the phantasm for abstraction and shows that all knowledge of nature begins in the interior senses.This lecture was given on July 16th, 2026, at Dominican House of Studies.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speaker:Fr.

Prof. Ryan Miller offers an introductory overview of the foundational terminology of Thomistic philosophy of nature — potency and act, the four causes, per se versus per accidens, the categories of substance, accident, and relation, and nature versus instrument — illustrating each distinction with modern scientific analogies and everyday examples like the conductor, combustion, phonemes, ionization, model species.This lecture was given on July 16th, 2026, at Dominican House of Studies.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speaker:Professor Ryan Miller is Core Fellow at the University of St Thomas in Houston and formerly Swiss National Science Foundation Doc.CH Fellow at the University of Geneva, working on Aristotelian approaches to the metaphysics of emergence in physical and computational systems.Keywords: Aquinas, Aristotle, Four Causes, Instrument, Nature, Per Accidens, Per Se, Potency and Act, Relation, Substance

Fr. Thomas Davenport argues against the Thomist intuition that artifice obscures nature, showing from Aquinas's account of art and artifacts that artificial forms are accidental forms rooted in the natural active and passive powers of substances, so that scientific instruments and experiments reveal rather than distort the natures they investigate.This lecture was given on July 18th, 2026, at Dominican House of Studies.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speaker:Fr.

Dr. Sarah E. Maple asks how we acquire an organic vision of beauty that is not merely material or visual, arguing from Aquinas's formal criteria of beauty (proportion, integrity, clarity) and Hans Urs von Balthasar's theological aesthetics (form and splendor, beholding and enrapture) that beauty belongs first to the human person, and that the artist's vocation is grounded in wonder, self-gift, and the sincerity of the body, culminating in a spirituality of artistic service.This lecture was given on April 21st, 2026, at University of Georgia.Support the Thomistic Institute Campus Chapter Program here: truth.thomisticinstitute.org/podAbout the Speaker:Dr. Sarah E.

Fr. Gabriel Torretta argues that beauty has become a "forbidden word" for our age due to the effects of German Idealism and Modernism; as a remedy, he proposes a recovery grounded in the Christian metaphysical tradition (Eriugena, Aquinas, Augustine), in which beauty is the attractive power by which God draws all things to himself and which requires an asceticism of the gaze.This lecture was given on April 28th, 2026, at University of Washington.Support the Thomistic Institute Campus Chapter Program here: truth.thomisticinstitute.org/podAbout the Speaker:Gabriel Torretta, O.P., is assistant professor of Theology at Providence College.
