"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)".
