The revelation in Christ of the mystery of God as Trinitarian love is at the same time the revelation of the vocation of the human person to love. This revelation sheds light on every aspect of the personal dignity and freedom of men and women, and on the depths of their social nature. “Being a person in the image and likeness of God … involves existing in a relationship, in relation to the other ‘I’”[36], because God himself, one and triune, is the communion of the Father, of the Son and of the Holy Spirit.

In the communion of love that is God, and in which the Three Divine Persons mutually love one another and are the One God, the human person is called to discover the origin and goal of his existence and of history. The Council Fathers, in the Pastoral Constitution Gaudium et Spes, teach that “the Lord Jesus Christ, when praying to the Father ‘that they may all be one … as we are one’ (Jn 17:21-22), has opened up new horizons closed to human reason by implying that there is a certain parallel between the union existing among the divine Persons and the union of the children of God in truth and love. It follows, then, that if man is the only creature on earth that God has willed for its own sake, man can fully discover his true self only in a sincere giving of himself (cf. Lk 17:33)” – Compendium of the Social Doctrine of the Church #34
