"An evil thought defiles the soul when it is deliberate and is consented to. Our Lord placed evil thoughts at the head of all crimes, because they are their principle and source." St. John Baptist de la Salle For Reflection: Evil thoughts come to all of us. When are they a defilement to the soul (a sin) according to this quote? Why are evil thoughts the "head of all crimes?" How are they the "principle and source" of sinful actions? (See tomorrow's Grace Line for a way to overcome evil thoughts.)
