The Liturgy of the Hours, also known as the Divine Office or the Work of God (Opus Dei), is the daily prayer of the Church, marking the hours of each day and sanctifying the day with prayer.  The Hours are a meditative dialogue on the mystery of Christ, using scripture and prayer.  At times the dialogue is between the Church or individual soul and God; at times it is a dialogue among the members of the Church; and at times it is even between the Church and the world.
