The Magnificat version of morning and evening prayer are “inspired” by the LOTH, but not really liturgical in any sense. They can be prayed as a personal devotion, nothing wrong with that, but a fuller meaning I believe, comes from praying the prayer of the universal Church, the Liturgy of the Hours. Just doing Morning and Evening Prayer in the LOTH shouldn’t be too onerous, maybe 15 min. each. What’s a half-hour during the day? Magnificat maybe saves you 10 minutes overall. Maybe better than nothing if stuck without your breviary and Internet access though.
Praying the LOTH is a liturgical act in the fullest sense and is to be commended even by the laity.
