The Church has numerous fathers who have influenced its dogma in substantial ways. Although none of them can be singled out as the most pivotal theologian of Church history, it can certainly be said that Saint Augustine of Hippo has long been a central figure to Christian thought, informing both on the nature of God and the nature of Christian morality.
He has been quoted throughout the ages by important Christian writers, such as Saint Thomas Aquinas, and has been listed as a strong influence by Pope Benedict XVI. Through his central place in the history of Christianity, some historians have appointed Saint Augustine particularly great importance in European and World history.
They have called him the last man of the Classical Age, and the first medieval man.
