A Voice from the Past - Gregory the Great

Differently to be admonished are the forward and the faint-hearted, For the former, presuming on themselves too much, disdain all others when reproved by them; but the latter, while too conscious of their own infirmity, for the most part fall into despondency. Those count all they do to be singularly eminent; these think what they do to be exceedingly despised, and so are broken down to despondency.

Gregory the Great, 540-604 AD, Pastoral Rule, Part III, Chapter VIII (The Nicene and Post Nicene Fathers, Volume XII (Part 2), Second Series, Philip Schaff and Henry Wace, translated by James Barmby, T & T Clark and Wm. B. Eerdmans, 1997, p. 29)
