14 Against this, drawing upon the vast range of patristic theology, de Lubac was able to demonstrate that salvation has always been considered a “social” reality. Indeed, the Letter to the Hebrews speaks of a “city” (cf. 11:10, 16; 12:22; 13:14) and therefore of communal salvation. Consistently with this view, sin is understood by the Fathers as the destruction of the unity of the human race, as fragmentation and division. Babel, the place where languages were confused, the place of separation, is seen to be an expression of what sin fundamentally is. Hence “redemption” appears as the reestablishment of unity, in which we come together once more in a union that begins to take shape in the world community of believers. We need not concern ourselves here with all the texts in which the social character of hope appears. Let us concentrate on the Letter to Proba in which Augustine tries to illustrate to some degree this “known unknown” that we seek. His point of departure is simply the expression “blessed life”. Then he quotes Psalm 144 :15: “Blessed is the people whose God is the Lord.” And he continues: “In order to be numbered among this people and attain to ... everlasting life with God, ‘the end of the commandment is charity that issues from a pure heart and a good conscience and sincere faith' ( 1 Tim 1:5)”. This real life, towards which we try to reach out again and again, is linked to a lived union with a “people”, and for each individual it can only be attained within this “we”. It presupposes that we escape from the prison of our “I”, because only in the openness of this universal subject does our gaze open out to the source of joy, to love itself—to God.
