"The Son of God took flesh in the womb of a woman, a virgin. Your cathedral is a living hymn of stone and light in praise of that act, unique in the annals of human history: the eternal Word of God entering our history in the fulness of time to redeem us by his self-offering in the sacrifice of the Cross. Our earthly liturgies, entirely ordered to the celebration of this unique act within history, will never fully express its infinite meaning. Certainly, the beauty of our celebrations can never be sufficiently cultivated, fostered and refined, for nothing can be too beautiful for God, who is himself infinite Beauty. Yet our earthly liturgies will never be more than a pale reflection of the liturgy celebrated in the Jerusalem on high, the goal of our pilgrimage on earth. May our own celebrations nonetheless resemble that liturgy as closely as possible and grant us a foretaste of it!
"Even now the word of God is given to us as the soul of our apostolate, the soul of our priestly life. Each morning the word awakens us. Each morning the Lord himself 'opens our ear' (cf. Is 50:5) through the psalms in the Office of Readings and Morning Prayer. Throughout the day, the word of God becomes the substance of the prayer of the whole Church, as she bears witness in this way to her fidelity to Christ. In the celebrated phrase of Saint Jerome, to be taken up in the XII Assembly of the Synod of Bishops next month: 'Ignorance of the Scriptures is ignorance of Christ' (Prol. in Is.). Dear brother priests, do not be afraid to spend much time reading and meditating on the Scriptures and praying the Divine Office! Almost without your knowing it, God’s word, read and pondered in the Church, acts upon you and transforms you. As the manifestation of divine Wisdom, if that word becomes your life 'companion', it will be your 'good counsellor' and an 'encouragement in cares and grief' (Wis 8:9)".
