"to give glory to the Trinity, from whom everything in the world and in history comes and to whom everything returns" (n. 55)

33. An initial view of this horizon is offered by the first page of Sacred Scripture, which indicates the moment when God's creative power makes the world out of nothing: "In the beginning God created the heavens and the earth" (Gn 1: 1). This view is deepened in the New Testament, going back to the very heart of the divine life, when John proclaims at the beginning of his Gospel: "In the beginning was the Word, and the Word was with God, and the Word was God" (Jn 1: 1). Before creation and as its foundation, revelation has us contemplate the mystery of the one God in the trinity of persons: the Father and his Word united in the Spirit. The biblical author who wrote the creation text could not have suspected the depths of this mystery. Even less could mere philosophical reflection have attained it, since the Trinity is beyond the capacities of our understanding and can only be known through revelation. Nevertheless, this mystery which infinitely transcends us is also the reality closest to us, because it is the very source of our being. For in God we "live and move and have our being" (Acts 17: 28), and what St Augustine says of God must be applied to all three divine persons: he is "intimior intimo meo" (Conf., 3, 6, 11). In the depths of our being, where not even our gaze can penetrate, the Father, Son and Holy Spirit, one God in three persons, are present through grace. Far from being a dry intellectual truth, the mystery of the Trinity is the life that dwells in us and sustains us.
