Subsequent generations viewed the Catholic victory as inevitable, but for Augustine's contemporaries the Ulfilan Arians were a serious menace.

This is the first volume to attempt a comprehensive overview of the evolution of the 'Arian' churches in the Roman world of Late Antiquity and their political importance in the late Roman kingdoms of the 5th-6th centuries, ruled by barbarian warrior elites. Bringing together researchers from the disciplines of theology, history and archaeology, and providing an extensive bibliography, it constitutes a breakthrough in a field largely neglected in historical studies. A polemical term coined by the Orthodox Church (the side that prevailed in the Trinitarian disputes of the 4th century C.E.) for its opponents in theology as well as in ecclesiastical politics, Arianism has often been seen as too complicated to understand outside the group of theological specialists dealing with it and has therefore sometimes been ignored in historical studies. The studies here offer an introduction to the subject, grounded in the historical context, then examine the adoption of Arian Christianity among the Gothic contingents of the Roman army, and its subsequent diffusion in the barbarian kingdoms of the late Roman world.

This book, The Plot Against the Church, was published prior to the beginning of the Second Vatican Council as a warning of what the dark powers had in store for the Church. The high ranking clerics, writing as Maurice Pinay, stated that the ultimate purpose of the Council was to remove the crime of Deicide from the Jews and assign it instead to the Romans. It is a scholarly work, worthy of consideration of all who would understand Christian history and Christian defense against forces seeking to destroy the Church and Faith. While written in 1962, Rabbi Louis Israel Newman wrote much the same from the Jewish side in his 1925 work Jewish Influence in Christian Reform Movements, which is quoted extensively in The Plot.

Arianism is the theological teaching attributed to Arius (ca. AD 250–336), a Christian presbyter in Alexandria, Egypt, concerning the relationship of God to the Son of God (Jesus of Nazareth). Arius asserted that the Son of God was a subordinate entity to God the Father. Deemed a heretic by the Ecumenical First Council of Nicaea of 325, Arius was later exonerated in 335 at the regional First Synod of Tyre, and then, after his death, pronounced a heretic again at the Ecumenical First Council of Constantinople of 381.Athanasius of Alexandria (b. ca. 296-298 – d. 2 May 373), also referred to as St. Athanasius the Great, St. Athanasius I of Alexandria, St Athanasius the Confessor and (primarily in the Coptic Orthodox Church) St Athanasius the Apostolic, was the 20th bishop of Alexandria. His episcopate lasted 45 years (c. 8 June 328 – 2 May 373), of which over 17 were spent in five exiles ordered by four different Roman emperors. He is considered to be a renowned Christian theologian, a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Egyptian leader of the fourth century.
