Evangelization is a command given by Christ to his apostles: ‘Go into all the world and proclaim the Gospel to every creature’. (Mk 16:15). This imperative phrase extends to all of us who have been baptised, who constantly have opportune and inopportune chances to put into practice what Christ commands. Knowing that the human being is made up of a body and a soul, neither should be neglected, and so they should be recognised in their entirety, but there is a hierarchy of things. When we realise that the message of the Gospel is a valuable message of salvation, we consequently lead our lives based on it. God, who knows all things, has also left us instructions so that we can live humanely without harming what touches the principles he has given us; the commandments are one way of understanding this. When we are willing to be instructed in divine values by following the decalogue, we are fulfilling our human duties, because ‘do not kill’ (Ex 20:13) is a natural law, which participates in the Eternal Law inscribed in the ‘heart’ of man and which can be recognised by reason, just as when we put all our energy into living the virtues, in other words, practising what is good, beautiful and true, we will consequently be ‘successful’ men and women. To be a good Christian is to be another Christ, and this makes us good citizens, good professionals, it is from the Gospel that we will have a humanity ordered towards the good, because the Lord of all willed it, and for this he sent his son who became incarnate and became man so that humanity could be elevated. The Church's mission, therefore, is to be an educator and thus to instruct us so that we can reach our goal, which is the contemplation of God ‘not only because it must also be recognised as a human society capable of providing education, but above all because it has the duty to proclaim to all people the way of salvation...’ . And in order to reach this path, it is necessary to understand man in an integral way, and this understanding is part of the Church's educational mission.
