Dr. John F. O’Neill is an Adjunct Professor of Moral Theology at Holy Apostles College and Seminary and also teaches High School full-time. His area of research is Trinitarian Theology in itself and especially as it illuminates creation and the economy of salvation, focusing on how creatures relate to God the Trinity through the divine missions, the imago Dei, and the sacraments. His book on Trinitarian Ecclesiology highlights the Trinitarian nature of the economy of salvation by explaining the union of Christ and the Church in light of the visible missions of the Son and the Holy Spirit.
