An earlier poster was debating whether to implement mid-day prayer or the Angelus. As both are rather short, why not pray both? The Angelus is a beautiful prayer, but the Divine Office is the prayer of the Church itself. With the holy sacrifice of the mass, the divine office is the perfect prayer of Christ offered to His Father, which the Church, the mystical body of Christ, makes Her own. There can be no greater prayer than the holy mass and the divine office (which really are one prayer - the one offering of the Church which drawings its grace and power from the eucharist). The Church strongly encourages the laity to participate in the divine office and in fact Vatican II encouraged all parishes to celebrate, at the very least, Sunday Vespers as a community. How many parishes do this?
Popular devotions, such as the Angelus, are wonderful, but they are not a substitution for the liturgy. We should be fostering both.
Prayed privately to myself, mid-day prayer, using the current Liturgy of the Hours, takes about 5 minutes…prayed vocally in a group would still be no more than 10.
