Justice is based on love, flows from it, and tends towards it. In the Passion and Death of Christ—in the fact that the Father did not spare his own Son, but for our sake made him sin—absolute justice is expressed, for Christ undergoes the Passion and cross because of the sins of humanity. This constitutes even a “superabundant” of justice, for the sins of man are compensated for” by the sacrifice of the Man-God. Nevertheless, this justice, which is properly justice “to God’s measure,” springs completely from love: from the love of the Father and of the Son, and completely bears fruit in love. Precisely for this reason the divine justice revealed in the cross of Christ is “to God’s measure,” because it springs from love and is accomplished in love, producing fruits of salvation. The divine dimension of redemption is put into effect not only by bringing justice to bear upon sin, but also by restoring to love that creative power in man thanks to which he once more has access to the fullness of life and holiness that come from God. In this way, redemption involves the revelation of mercy in its fullness.
The Paschal Mystery is the culmination of this revealing and effecting of mercy, which is able to justify man, to restore justice in the sense of that salvific order which God willed from the beginning in man and through man, in the world. The suffering Christ speaks in a special way to man, and not only to the believer. The non-believer also will be able to discover in him the eloquence of solidarity with human lot, as also the harmonious fullness of a disinterested dedication to the cause of man, to truth and to love.
