One can never sufficiently stress the fact that evangelization does not consist only of the preaching and teaching of a doctrine. For evangelization must touch life: the natural life to which it gives a new meaning, thanks to the evangelical perspectives that it reveals; and the supernatural life, which is not the negation but the purification and elevation of the natural life.
This supernatural life finds its living expression in the seven sacraments and in the admirable radiation of grace and holiness which they possess.
Evangelization thus exercises its full capacity when it achieves the most intimate relationship, or better still, a permanent and unbroken intercommunication, between the Word and the sacraments. In a certain sense it is a mistake to make a contrast between evangelization and sacramentalization, as is sometimes done. It is indeed true that a certain way of administering the sacraments, without the solid support of catechesis regarding these same sacraments and a global catechesis, could end up by depriving them of their effectiveness to a great extent. The role of evangelization is precisely to educate people in the faith in such a way as to lead each individual Christian to live the sacraments as true sacraments of faith- and not to receive them passively or reluctantly.
