To evangelize is to show the way, to teach the art of life, and the Gospel of Jesus is the best source of universal rules for that. The Church has always been evangelizing, and will keep doing so till the end of the world. The Christian family takes part in this ongoing process of evangelization, the family which is the first and - for many reasons - the most important way of the Church (cf. Letter to Families 2). In this article the author discusses the question of the evangelization of the family, in the family and through the family, as a great task that needs to be constantly discovered and undertaken.
