Whoever wants to please both the world and God leads one of the most unhappy of lives. You shall see how. Here is someone who gives himself up to the pleasures of the world or develops some evil habit. How great is his fear when he comes to fulfil his religious duties; that is, when he says his prayers, when he goes to Confession, or wants to go to Holy Communion! He does not want to be seen by those with whom he has been dancing and passing nights at the cabarets, where he has been giving himself over to many kinds of licentiousness. Has he come to the stage when he is going to deceive his confessor by hiding the worst of his actions and thus obtain permission to go to Holy Communion, or rather, to commit a sacrilege? He would prefer to go to Holy Communion before or after Mass, that is to say, when there is no one present. Yet he is quite happy to be seen by the good people who know nothing about his evil life and among whom he would like to arouse good opinions about himself. In front of devout people he talks about religion. When he is with those who have no religion, he will talk only about the pleasures of the world. He would blush to fulfil his religious practices in front of his companions or those boys and girls who share his evil ways.
