Show the faith–it’s a more important first step than teaching it:
41. Without repeating everything that we have already mentioned, it is appropriate first of all to emphasize the following point: for the Church, the first means of evangelization is the witness of an authentically Christian life, given over to God in a communion that nothing should destroy and at the same time given to one’s neighbor with limitless zeal. As we said recently to a group of lay people, “Modern (woman or) man listens more willingly to witnesses than to teachers, and if (she or) he does listen to teachers, it is because they are witnesses.”[Pope Paul VI, Address to the Members of the Consilium de Laicis (2 October 1974): AAS 66 (1974), p. 568] St. Peter expressed this well when he held up the example of a reverent and chaste life that wins over even without a word those who refuse to obey the word.[Cf. 1 Pt 3:1] It is therefore primarily by her conduct and by her life that the Church will evangelize the world, in other words, by her living witness of fidelity to the Lord Jesus- the witness of poverty and detachment, of freedom in the face of the powers of this world, in short, the witness of sanctity.
This observation, which I believe to be even more accurate today, has always been true to a great degree. It’s been true among believers (What would be the proportion of those devoted to Pope John Paul II who admired the man for his public witness over his particular writings?) and non-believers alike. It’s the essence of the writer’s maxim: show don’t tell.
The importance of the witness of personal sanctity is something perhaps lost on many modern bishops. It is their way out of the collective shame and scandal in which they are buried. It is the only way people will listen.
