I say the same of humility and of all the virtues; the wiles of the devil are terrible, he will run a thousand times round hell if by so doing he can make us believe that we have a single virtue which we have not. And he is right, for such ideas are very harmful, and such imaginary virtues, when they come from this source, are never unaccompanied by vainglory; just as those which God gives are free both from this and from pride.
Teresa of AvilaHalf-instructed confessors have done my soul great harm; for I could not always have such learned ones as I would have desired. They certainly did not wish to deceive me, but the fact was that they knew no better. Of something which was a venial sin, they said it was no sin, and out of a very grave mortal sin they made a venial sin. This has done me such harm, that my speaking here of so great an evil, as a warning to others, will be readily understood.
Teresa of AvilaIf I were to give advice, I would say to parents that they ought to be very careful whom they allow to mix with their children when young; for much mischief thence ensues, and our natural inclinations are unto evil rather than unto good.
Teresa of Avila
