Letter XXVI. To Guy, Bishop of Lausanne
(Circa A.D. 1130.)
You have undertaken great things; you have need of courage. You have become a watcher for the house of Israel; you have need of prudence. You are a debtor both to the wise and unwise; you have need of righteousness.
Lastly, you have, above all, need of temperance and self-control, so that one who has preached to others may not become (which may God forbid!) a reprobate.
