CSDC 31

The Face of God, progressively revealed in the history of salvation, shines in its fullness in the Face of Jesus Christ crucified and risen from the dead. God is Trinity: Father, Son, and Holy Spirit; truly distinct and truly one, because God is an infinite communion of love. God's gratuitous love for humanity is revealed, before anything else, as love springing from the Father, from whom everything draws its source; as the free communication that the Son makes of this love, giving himself anew to the Father and giving himself to mankind; as the ever new fruitfulness of divine love that the Holy Spirit pours forth into the hearts of men (cf. Rom 5:5). By his words and deeds, and fully and definitively by his death and resurrection³⁰ Cf.

Rom 8:15; Gal 4:6), and therefore brothers and sisters among ourselves. It is for this reason that the Church firmly believes that “the key, the centre and the purpose of the whole of man's history is to be found in her Lord and Master”³¹ Second Vatican Ecumenical Council, Pastoral Constitution Gaudium et Spes, 10: AAS 58AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 58 (1966) at vatican.va — scanned PDF (1966), 1033..
