Abstract
Summary: In this paper, I will try to present the idea of economic triadology as it appears in St. Irenaeus, Tertullian and St. Hippolytus, during conflicts with the modalists of their time. Through comparative analysis, I will strive to highlight the particularities of their learning as well as common motives and argumentation. I will also point out the major shortcomings of the triadology thus established, as well as the elements that the Church will recognize as an authentic expression of her own tradition.
