But doesn’t every rite have a cycle of daily offices which, if followed completely, would leave little time for other devotions? It doesn’t seem like that alone would preclude the organic development of private devotions.
Perhaps but I’m yet to see a tradition aside from the Syriacs that have so faithfully maintained the monastic observance of offices on such a wide level. Additionally, if one has a festal rite that takes another 2hrs. on top of the morning office and the mass on a feast, I don’t know what one would want to supply it with more. I’ve also never seen the popular engagement of the laity in another tradition that I do in Syriac liturgy; if you attend a Syriac Orthodox office, depending on the church, a lay woman might be chanting the office at the same choir desk as the bishop (and those who push “popular participation” try to introduce to the Maronite Church
). It has been my experience that a good number of laity would come to the 40min. vespers on Wednesdays and Saturdays, and sing at the choir desk from young to old - I don’t know what supplementary devotional would be needed.
Ziyaah, in my experience, has been particular to the Maronites. I have not seen this amongst others Syriacs. Even that, though, seems to be a development in a parochial setting (I haven’t seen it done in any Maronite monastery during conventual liturgy).
One additional rite that might be almost devotional in character that I can think of is the
Shel el-Bakhour - following a liturgy on the anniversary of someone’s death, a hymn from the
Jinnaz (funerary office) is sung while the priest incenses the altar and the people. Ideally, there should also be
gharbaniyyah (mix of grains and nuts), which is blessed and distributed. Again, I would speculate this is parochial in origin and probably (at least the
Shel el-Bakhour addendum to liturgy) is an imitation of the Melkites doing the commemorative service at the end of the Divine Liturgy.
