Gregory Heille

Fr. Gregory Heille, OP, DMin, serves as Professor of Preaching and Evangelization at Aquinas Institute of Theology and directs the Doctor of Ministry in Preaching program. A Dominican Friar of the Province of St. Albert the Great USA, he also animates the global Dominican Preaching Network, connecting his academic work with the Order's 800-year preaching tradition.

His educational foundation includes:

• DMin (Preaching), Western Theological Seminary
• MDiv, Aquinas Institute of Theology
• MA (Liturgy), Aquinas Institute of Theology
• BA (Mathematics), St. John's University

Fr. Heille's research pioneers intersections between homiletics and critical social issues, with special focus on racial equity in preaching and cultural evangelization. His scholarship develops practical frameworks for addressing systemic injustice through sermon construction while maintaining theological depth, reflecting the Dominican commitment to veritas (truth) in contemporary contexts. This work manifests in courses like 'Preaching and Racism: Finding Our Way Forward' that equip ministers for transformative practice.

Analysis of his publications reveals consistent engagement with preaching's evolving role in Catholic life—from Pope Francis's missionary communication (2015) to urgent racial justice imperatives (2023). His output demonstrates methodological rigor in bridging academic theology with pastoral application, particularly through the lens of synodality and lay ecclesial ministry as seen in his forthcoming work on Eucharistic preaching.

As DMin program director, Fr. Heille mentors doctoral candidates in advanced homiletic research while expanding the global Dominican Preaching Network's reach. His leadership cultivates international collaborations that disseminate homiletic resources across cultural boundaries, strengthening preaching as a catalyst for church renewal and societal transformation through the Dominican charism of truth-seeking communication.
