"Contemplative prayer is the simple expression of the mystery of prayer. It is a gaze of faith fixed on Jesus, an attentiveness to the word of God, a silent love. It achieves real union with the prayer of Christ to the extent that it makes us share in his mystery" (Catechism of the Catholic Church, 2724).
"Meditation is a prayerful quest engaging thought, imagination, emotion, and desire. Its goal is to make our own in faith the subject considered, by confronting it with the reality of our own life"(Catechism of the Catholic Church, 2723).
