The justice to which man is called, is a demanding response to the justice of God that has the lines of Mercy and Forgiveness, of Grace and of Fidelity.
At the same time we note, especially in the writings of Wisdom, how the justice of God is addressed in particular to the poor and the suffering. We read in Psalm 98 that “The Lord has made his salvation known, in the eyes of the people he has revealed his justice”. Yet in Psalm 103 we read that “the Lord has done deeds of justice, has made the right to all the oppressed”.
This justice between God and man is brought to completion by Christ, becoming “a new and definitive covenant, as messianic fulfilment of the redeeming justice of God and eschatological anticipation of ‘the new heavens and of the new earth in which justice will have stable dwelling’ (2 Pt 3,13)”. As it was emphasized by Pope Francis in the Encyclical Lumen Fidei, faith is in close relation with the covenant with a faithful God, that establishes a relationship of love with the man by addressing his Word.
The aim of man is not in fact the domain of created reality, but the contemplation of God: man reaches this aim walking that path made of commitment and effort to orient the whole created reality, with and through the man, in that finalistic order that has God as objective. In this sense, the relationship between justice and faith becomes central and fundamental, precisely because there cannot be one without the other. Or better the faith, in particular the faith in Jesus Christ, arises as the horizon of pre-comprehension of justice, which in turn receives from faith a new light.
Pope Francis says that only through the Incarnation, that is sharing our humanity with us, “the knowledge of love can attain the fullness” (Lumen Fidei, 29).
The light of love, continues the Pope, “turns on when we are touched in the heart, accepting the interior presence of the beloved, which allows us to recognize his mystery” (Lumen Fidei, 31).
We must now continue to move in this direction, making a step forward. The central proclamation of the message of Jesus concerns the Kingdom of God: it is a reality that is already present and that will have a fulfilment in the future. The Kingdom is therefore characterised by its free, just nature: it is a gift. But precisely because it is a gift, it must be accepted in a free and voluntary way and, especially, it must have consequences in the act. It is a gift which in turn must be donated, communicated, announced, testified.
The faith in the Kingdom is the faith in the justice of God, in his promise of salvation, in a new world where justice, mercy and peace will reign for ever.
Accepting with wonder and newness of heart the message of the Beatitudes means putting ourselves in a dimension of service towards all men and women, for the love of the Lord. In this perspective, the faith in Jesus Christ urges us to open ourselves to God and to live according to all the dimensions and to the requests of the Gospel.
