In communion with the holy Mother of God
Medieval piety in the West developed the prayer of the rosary as a popular substitute for the Liturgy of the Hours. In the East, the litany called the Akathistos and the Paraclesis remained closer to the choral office in the Byzantine churches, while the Armenian, Coptic, and Syriac traditions preferred popular hymns and songs to the Mother of God. But in the Ave Maria, the theotokia, the hymns of St. Ephrem or St. Gregory of Narek, the tradition of prayer is basically the same.
