In debates, if you say a few words about religion you will prevail. Let the person who has a different opinion give free rein to his thoughts and speak as much as he likes. Let him sense that he is addressing himself to a calm and uncontentious person. Influence him through your graciousness and prayer and then speak briefly. You achieve nothing if you speak heatedly and tell him, for example, ‘What you’re saying is untrue, a downright lie!’ What will you achieve? Be as sheep among wolves. What should you do? Show indifference outwardly, but be praying inwardly. Be prepared, know what you are talking about and speak boldly and to the point, but with saintliness, meekness and prayer. But in order to be able to do this, you must become saints.
