Jesus Christ is our model, the model for every Christian. You are well aware of this because you have heard it and reflected on it so often. You have also taught this to many people in the course of your apostolate of friendship (true friendship, with a divine meaning) which by now has become a part of you. And you have recalled this fact, when necessary, when using the wonderful means of fraternal correction, so that the person who was listening to you might compare his behaviour with that of our first born Brother, the Son of Mary, Mother of God and our Mother also.

Jesus is the model for us. He himself has told us so: discite a me, learn from me. Today I want to talk to you about a virtue which, while it is neither the only virtue, nor the most important one, nevertheless operates in a Christian's life like salt, preserving it from corruption; it is also the touchstone of the apostolic soul. The virtue is holy purity.

We know full well that theological charity is the highest virtue. But chastity is a means sine qua non, an indispensable condition if we are to establish an intimate dialogue with God. When people do not keep to it, when they give up the fight, they end up becoming blind. They can no longer see anything, because 'the animal man cannot perceive the things that are of the Spirit of God'.

We, however, wish to look through unclouded eyes, encouraged as we are by Our Lord's teaching: 'Blessed are the pure of heart, for they shall see God.' The Church has always understood these words as an invitation to chastity. As St John Chrysostom writes, 'Those who love chastity, whose consciences are completely clear, keep their hearts pure. No other virtue is so necessary in order to see God.'
