The complete fulfilment of the human person, achieved in Christ through the gift of the Spirit, develops in history and is mediated by personal relationships with other people, relationships that in turn reach perfection thanks to the commitment made to improve the world, in justice and peace. Human activity in history is of itself significant and effective for the definitive establishment of the Kingdom, although this remains a free gift of God, completely transcendent. Such activity, when it respects the objective order of temporal reality and is enlightened by truth and love, becomes an instrument for making justice and peace ever more fully and integrally present, and anticipates in our own day the promised Kingdom. Conforming himself to Christ the Redeemer, man perceives himself as a creature willed by God and eternally chosen by him, called to grace and glory in all the fullness of the mystery in which he has become a sharer in Jesus Christ⁶⁹ Cf.

Mt 25:35-37).
