"It is not by the display of power and pomp, cavalcades of retainers, and richly-houseled palfreys, or by gorgeous apparel, that the heretics win proselytes; it is by zealous preaching, by apostolic humility, by austerity, by seeming, it is true, but by seeming holiness. Zeal must be met by zeal, humility by humility, false sanctity by real sanctity, preaching falsehood by preaching truth." A small group of priests formed around Dominic, but soon left him since the challenge and rigours of a simple lifestyle together with demanding preaching discouraged them.
