Against Praxeas

Devastating! A powerful defense of the Trinitarian doctrine, Against Praxeas by Tertullian demolishes the Unitarian view of God using Scripture and logic. The first to challenge heresy in writing, Tertullian is the oldest extant Latin writer to use the term Trinity and give a formal exposition of Trinitarian theology. See the Son as distinct from the Father and the Spirit from both the Father and the Son. "These Three are One substance, not one person", where singularity refers to the unity of the substance not the number, revealing the distinction of personality.
