These wonderful words of Sirach sum up the hymn of praise, sung in every age and under every sky, to the Creator who reveals himself through the immensity and splendour of his works. Although in still imperfect ways, many voices have recognized in creation the presence of its Author and Lord. Biblical revelation is set within this broad experience of religious awareness and human prayer, putting the divine seal upon it. In communicating the mystery of the Trinity to us, it helps us perceive in creation itself not only the marks of the Father, source of all life, but also those of the Son and the Spirit.
Day pours out the word to day, and night to night imparts knowledge.
The ear of the heart must be free of noise in order to hear this divine voice echoing in the universe. Along with revelation properly so-called, contained in Sacred Scripture, there is a divine manifestation in the blaze of the sun and the fall of night. We can ask ourselves how it is possible in Christian experience for contemplation of the Trinity to be fostered through creation, discerning there not only the reflection of the one God in a generic sense, but also the marks of the individual divine persons. So when we contemplate with wonder the universe in its grandeur and beauty, we must praise the whole Trinity, but in a special way our thoughts turn to the Father from whom everything flows, as the source and fullness of being itself. In the light of the Christian faith, creation particularly calls to mind the Holy Spirit in the dynamism that marks the relations between things, within the macrocosm and the microcosm, and is apparent especially wherever life is born and develops.
