I had never thought of lectio divina as something done in congregation. My understanding, according to what I know of the Rule of St. Benedict and its application, is that it is something done by the monk in his cell, apart from his private prayers and prayers in church. What you described, though, very much resembles traditional Western Rite and Benedictine Matins, which is composed mostly of Psalm readings, Scripture readings, hymns, a Gospel reading, and sections of a Patristic sermon and/or life of a saint. But, to me, actual lectio divina, would be private study and reading, in principal. I could be wrong, though.
