Fructuosus of Braga
No man shall rely upon chastity in the past, for none whose hearts are tainted by women can become holier than David or wiser than Solomon. That none may assume that his chastity is safe in the presence of a woman related to him, let him remember how Tamar was corrupted by her brother Amnon when he pretended to be ill. Accordingly, both monks and nuns should live so chastely that they may have a good report, not only before God but also before people, and may leave to those who follow an example of sanctity. - "General Rule for Monasteries 17"
