"It is a common trait among the heretics and schismatics;  schism and heresy have almost always, for their point of departure, a regret for the past, the claim or the dream of going back to the fountain-source of a religious idea, to the discipline or the faith of an apostolic age." (Monceaux, Histoire littéraire de l'Afrique chrétiene; cited in Knox, Enthusiasm, p.60)
