Let him never cease from prayer, who has once begun to pray, even though his life is ever so bad. For prayer is the only way to amend one's life and without prayer it will never be mended. Let him not be tempted of the devil, as I was, to give up prayer on account of one's unworthiness. Let such a one rather believe that if he will only repent and pray, our Lord will still hear and answer.
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.
