Half-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 AvilaMuch more is accomplished by a single word of the Our Father said, now and then, from our heart, than by the whole prayer repeated many times in haste and without attention.
Teresa of AvilaWhenever conscience commands anything, there is only one thing to fear, and that is fear.
Teresa of AvilaHow often I failed in my duty to God, because I was not leaning on the strong pillar of prayer.
