As a first step, we can respond to this question with another: what is this "reality"? What is real? Are only material goods, social, economic and political problems "reality"? This was precisely the great error of the dominant tendencies of the last century, a most destructive error, as we can see from the results of both Marxist and capitalist systems. They falsify the notion of reality by detaching it from the foundational and decisive reality which is God. Anyone who excludes God from his horizons falsifies the notion of "reality" and, in consequence, can only end up in blind alleys or with recipes for destruction.
The first basic point to affirm, then, is the following: only those who recognize God know reality and are able to respond to it adequately and in a truly human manner. The truth of this thesis becomes evident in the face of the collapse of all the systems that marginalize God.
Yet here a further question immediately arises: who knows God? How can we know him? We cannot enter here into a complex discussion of this fundamental issue. For a Christian, the nucleus of the reply is simple: only God knows God, only his Son who is God from God, true God, knows him. And he "who is nearest to the Father’s heart has made him known" (John 1:18). Hence the unique and irreplaceable importance of Christ for us, for humanity. If we do not know God in and with Christ, all of reality is transformed into an indecipherable enigma; there is no way, and without a way, there is neither life nor truth.
God is the foundational reality, not a God who is merely imagined or hypothetical, but God with a human face; he is God-with-us, the God who loves even to the Cross. When the disciple arrives at an understanding of this love of Christ "to the end", he cannot fail to respond to this love with a similar love: "I will follow you wherever you go" (Luke 9:57).
We can ask ourselves a further question: what does faith in this God give us? The first response is: it gives us a family, the universal family of God in the Catholic Church. Faith releases us from the isolation of the "I", because it leads us to communion: the encounter with God is, in itself and as such, an encounter with our brothers and sisters, an act of convocation, of unification, of responsibility towards the other and towards others. In this sense, the preferential option for the poor is implicit in the Christological faith in the God who became poor for us, so as to enrich us with his poverty (cf. 2 Corinthians 8:9).
Yet before we consider what is entailed by the realism of our faith in the God who became man, we must explore the question more deeply: how can we truly know Christ so as to be able to follow him and live with him, so as to find life in him and to communicate that life to others, to society and to the world? First and foremost, Christ makes his person, his life and his teaching known to us through the word of God.
At the beginning of this new phase that the missionary Church of Latin America and the Caribbean is preparing to enter, starting with this Fifth General Conference in Aparecida, an indispensable pre-condition is profound knowledge of the word of God. To achieve this, we must train people to read and meditate on the word of God: this must become their staple diet, so that, through their own experience, the faithful will see that the words of Jesus are spirit and life (cf. John 6:63). Otherwise, how could they proclaim a message whose content and spirit they do not know thoroughly? We must build our missionary commitment and the whole of our lives on the rock of the word of God. For this reason, I encourage the Bishops to strive to make it known.
An important way of introducing the People of God to the mystery of Christ is through catechesis. Here, the message of Christ is transmitted in a simple and substantial form. It is therefore necessary to intensify the catechesis and the faith formation not only of children but also of young people and adults. Mature reflection on faith is a light for the path of life and a source of strength for witnessing to Christ. Most valuable tools with which to achieve this are the Catechism of the Catholic Church and its abridged version, the Compendium of the Catechism of the Catholic Church.
In this area, we must not limit ourselves solely to homilies, lectures, Bible courses or theology courses, but we must have recourse also to the communications media: press, radio and television, websites, forums and many other methods for effectively communicating the message of Christ to a large number of people.
