The Thomistic Institute

Fr. Irenaeus Dunlevy argues that church architecture is "incarnational" when it corresponds to a true cosmological vision of reality ordered through and toward the Logos and embodies the principles revealed to Moses on Sinai, and "iconoclastic" when, in its modernist self-referentiality, it rejects that order and fails to communicate the body and head of Christ made present in the liturgy.

This lecture was given on July 19th, 2026, at Glencomeragh House.

Fr. David Goodill explains that, for Aquinas, conscience is not a power of the soul but an act of the intellect rooted in the natural habit of synderesis and formed by the virtues, above all prudence, so that it reflects the deepest interiority of the person.

Prof. Lewis Ayres presents Newman's account of conscience as, not a private inner voice, but the echo of God's voice within the human being, that although refracted by sin and therefore requiring long formation in humility and obedience, is an entry into true fraternity.
