11. The couple that loves and begets life is a true, living icon – not an idol like those of stone or gold prohibited by the Decalogue – capable of revealing God the Creator and Saviour. For this reason, fruitful love becomes a symbol of God’s inner life (cf. Gen 1:28; 9:7; 17:2-5, 16; 28:3;35:11; 48:3-4). This is why the Genesis account, following the “priestly tradition”, is interwoven with various genealogical accounts (cf. 4:17-22,25-26; 5; 10; 11:10-32; 25:1-4, 12-17, 19-26; 36). The ability of human couples to beget life is the path along which the history of salvation progresses. Seen this way, the couple’s fruitful relationship becomes an image for understanding and describing the mystery of God himself, for in the Christian vision of the Trinity, God is contemplated as Father, Son and Spirit of love. The triune God is a communion of love, and the family is its living reflection. Saint John Paul II shed light on this when he said, “Our God in his deepest mystery is not solitude, but a family, for he has within himself fatherhood, sonship and the essence of the family, which is love. That love, in the divine family, is the Holy Spirit”.6 The family is thus not unrelated to God’s very being.7 This Trinitarian dimension finds expression in the theology of Saint Paul, who relates the couple to the “mystery” of the union of Christ and the Church (cf. Eph 5:21-33).
