The new translation of the Sanctus is a fine example of why the new English Mass is necessary; and of how translation should be done.
The original Sanctus Sanctus Sanctus Domine Deus Sabaoth comes from Isaiah 6. Readers will not need to be reminded that Domine translates YHWH, the unutterable Name of the Jewish God ... that is to say, our God, for we ought never to forget that (as Pius XI said in the era of Hitler) we are all spiritually Semites. Before the Preface, the priest has invited us to Make Eucharist (give thanks) to YHWH our God; now we join the angels in shouting his holiness.
He is YHWH God SBAOTH; an ancient cult title which the Vulgate properly translates as 'God of armies'; he is the God who went to war before David and the people of Israel, his chosen, throughout their ... oops, I think I should have written 'our' ... history. But how to translate SBAOTH?
Old ICEL rendered 'Holy, holy, holy Lord, God of power and might'. Very nasty, because it makes LORD a final monosyllable that in saying and singing gets psychologically and physically (we are just coming to the end of our puff) lost. It puts a heavy break before the phrase 'God of power and might' and thereby breaks up the integrity of the Hebrew original.
But there would be something awkward in a literal rendering 'God of Armies'. If that had been proposed, the furore would have been understandable. New ICEL has done a very wise thing. It has gone back to the archaic English phrase 'God of hosts'. where 'hosts' is old English for 'armies' (cf Wycliff and the Authorised Version and Cranmer's Prayer Book). 'Sabaoth' is an archaism; what more fitting than an archaism to render it; an archaism which reminds us of our Hebrew roots and of the long history of Biblical and liturgical English. This is precisely how translation should be done.
Someone should tell those clergy who are campaigning against the new translation (in organisations such as "What if we just said Wait until Ratzinger is dead") that, in very many cases, they are campaigning against the wording with which Anglicans have been familiar for 450 years. This is very unecumenical.
