To every man, however holy he may be, there always remains some imperfection, because he has been drawn from nothingness: so that we do no injury to the saints when, in recounting their virtues, we relate their sins and defects; but, on the contrary, those who write their lives seem, for this reason, to do a great injury to making by concealing the sins and imperfections of the saints, under pretence of honouring them, not referring to the commencement of their lives, for fear of diminishing the esteem of their sanctity. Oh, no, indeed, this is not to act properly; but it is to wrong the saints and all posterity.
--St. Francis de Sales, Consoling Thoughts
