Martin Thornton had many insights in the purpose, nature, and practice of the Divine Office. Here is a summary of his insights, with my own commentary mixed in.
(1) The Our Father prayer is the sole dominical basis for the Divine Office; it establishes its corporate nature, its teleology, its disposition, its paradigm. The Didache confirms its centrality to corporate set prayer. Recourse by other commentators to Ps. 119:164 and the like are important, clarifying, supportive, authoritative, but secondary.
(2) The Divine Office can only be understood theologically within the larger theology of threefold Regula — Divine Office-Mass-Devotion — which is the ascetical application of the doctrine of the Trinity. Divine Office associates with and emphasizes the Father; Mass with the Son, and Devotion with the Spirit. This is not modalism but a framework for our devout yet imperfect ascetical response to the “stupendously rich reality” of God (to quote Baron von Hügel).
(3) Jesus is the source of the threefold Regula:
- His meals together, dining together, communing against the conventions of the day: this is the model of the Eucharist;
- His adoration and perfect prayer to His Father: this is the model of the Divine Office;
- His life lived with people, healing, teaching, listening, leading, breaking open Scripture in fresh ways: this is the model of Devotion.
Incorporated into Him by Baptism, we slowly learn to pray like Him along these three dimensions. The threefold Regula constitutes the repeatable part of Baptism.
Each dimension of the threefold Regula carries a particular psychological/behavioral disposition — Oblation with the Divine Office; Contemplation with the Mass; Obedience with Devotion — that integrated into a threefold whole of prayer manifest the fundamental corporate response to God as well as the more developed answer to the question, “Brethren, what shall we do?” (Acts 2.37b). Regula presumes baptismal status, repentance, the actuality of the Holy Spirit in our lives and builds upon the praxis of Acts 2.42.
(4) The Divine Office must possess and enact objective praise to the Father by the Body of Jesus (Baptized, Saints, Angels) which despite our frailty we join by the help and grace of Christ; hence, it does not primarily “sanctify the time.” Sanctification of time is by our attentiveness and obedience to the abundant activity of the Holy Spirit to whom we open ourselves not through the Divine Office but through Devotion activities (our “infinitely variable” baptismal ministry rooted in Scripture) — seeking and serving Christ in all persons by means of the Holy Spirit. See Robert Taft’s The Liturgy of the Hours in East and West, pp. 357-9; Dix’s “sanctification of time” theology of the Office is devout yet erroneous.
(5) Honest assessment of the pastoral situation today tends to conclude that the reason few people do the Cranmerian form likely stems from the fact that the authorized Anglican Divine Office used virtually unchanged today was crafted for a late-medieval society still well within Christendom. Further, the vernacular Bible was new and there was real pastoral necessity to have people hear it in English; neither of which pertains today. Hence, the Anglican Divine Office has rightfully endured as a Benedictine inheritance, yet now some kind of reform or modification appears necessary.
(6) Because the Father Almighty is ontological and axiological Other — that is, immutable in all ways, somewhere in the daily life of Prayer must be praise corresponding to this Person, praise that is immutable, strictly invariable. If applied thoroughly, this could mean adding a daily period of strictly objective prayer as an additional Hour of the day, a “little hour” added to the day (a day which can and even should still include the historic Cranmerian form).
This means, as a devout experiment rooted in doctrine and pastoral reality, a “Prologue Office of Praise” with no lectionaries, no seasonal antiphons, no consecutive psalter, no optional collects, no permissiveness whatsoever. All of those are retained in the Daily Office of Readings. The ideal is memorization of the Prologue Office of Praise, and no books. Again, the paradigm is “Our Father, who art in heaven . . .”: something along the lines of a “pledge of allegiance” to God Almighty.
Thornton trod very carefully in his writing on the Offices, knowing that the Cranmerian daily Office functions as the Anglican “third rail”: “Do Not Touch.” Well aware of Cranmer’s ascetical brilliance (see The Function of Theology), in Prayer: A New Encounter, he suggested devout experimentation along the lines of what I have proposed here — the Our Father theologically expanded by means of the Nicene Creed — with our need for regular Scripture immersion satisfied through a historic Cranmerian Daily Office of Readings: patterned reading of the Bible (including consecutive Psalter and lectionaries) with Canticles and Collects within the fellowship of the living Church. (Incidentally, he also suggested there was a need for daily contemplative prayer along the lines of what today is called Centering Prayer. Thornton suggested at least two hours per week of silence, or about twenty minutes per day, which is exactly the recommendation for beginners made by advocates of Centering Prayer.)
The primary text to consider to begin to grapple with Thornton’s theology of Office/Regula is Pastoral Theology: A Reorientation. This was his second book and set out the theological fundamentals of the remainder of his writing. Secondary texts to consider are Christian Proficiency, The Purple Headed Mountain, English Spirituality, The Rock and the River, The Function of Theology, My God, and Prayer: A New Encounter.
What must be said is that of all the topics of corporate spiritual life/journey — that is, “Ascetic” — it is the topic of Divine Office/Regula that received the most attention in his work, which was always the fruits of tremendous erudition, insight, and reflection. Thornton’s theology of Regula must be reckoned with today in any writing about the Divine Office; else in my view it is like writing about the theology of the Eucharist and leaving out Aquinas, or writing about the Trinity and leaving out Augustine.
