A Commentary on the Book of the Psalms, Preserving Christian Publications, Boonville, New York 2008, American ISBN 978-0-9802084-4-3, is a fine book which would feed the spirituality of those who wish to benefit from the surface text of the psalms. But, as Bishop Moriarty explained "it omits those portions which are purely philological, or which relate to the discrepancy and reconciliation of texts and versions". And, frankly, what the Archdeacon omitted is the sort of thing I, moi, love getting into.
Does all that 'dry' historical stuff really matter? Let me briefly take Psalm 91 (Vg-LXX) = 92 (MT). Bonum est confiteri, as Anglicans have always called it. There is a rabbinical legend that this was the song of praise uttered by Adam as the first Sabbath dawned upon the world, and that it descended by tradition as the special hymn for that day. Moving into historical time, what we do know is that it was sung in the Temple on the Sabbath at the offering of the Tamid, the first lamb of public sacrifice, in the morning, when the wine offering was poured out and the Breads were offered (Numbers 28). And verse 2 refers to both the morning and the evening sacrifices of the lamb. In the old Breviary, it was still in use on the Sabbath at Lauds because "the Roman Church, amongst other tokens of the poweful Judaizing influence which affected its earliest days, retains it as part of Saturday Lauds". Apparently, rabbinic Judaism still uses it on the Sabbath. And its Sabbath use survived the revision of the Palter under Pope S Pius X. Indeed, even the Liturgy of the Hours retains its use on alternate Sabbaths.
I am aware that not everybody, in their journey of Faith, needs the same props. But I don't see what harm such informations will do to any presbyter or laic as they say Saturday Lauds before setting off up the Hill to the Altar of Sacrifice.
In my second paragraph, I high-lighted one sentence. It was borrowed from A Commentary on the Psalms: from Primitive and Medieval writers; and from the Various Office Books and Hymns of the Roman, Mozarabic, Ambrosian, Greek, Coptic, Armenian and Syriac rites. By The Rev. J.M. Neale, D.D., sometime Warden of Sackville College, East Grinstead, and the Rev. R.F. Littledale, Ll.D., sometime scholar of Trinity College Dublin. 1887.
A ripe product of the scholarship of the second generation of the Catholic Revival in the Church of England (and Ireland). It does what it says on the tin. I doubt if it's still in print ...
