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.

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