A church famed for its polyphonic and chant traditions and its support of the arts, it has taken the "Reform of the Reform" in a slightly different direction from places such as the Church of Our Saviour or St. Agnes in St. Paul, Minnesota, or perhaps it simply has not re-arranged their musical program or liturgy much since the earliest, tenative changes of Advent 1964. A friend of mine once remarked, in describing their masses to me, as I have never visited, it was rather like time-travelling to a somewhat liturgically conservative parish in Europe circa 1965, an unsettled if historically interesting time to be sure; I say this not as a criticism but simply by way of explanation. I believe they use the 1970 missal, but with a slightly different translation of the various dialogues between priest and people that, while closer to the original Latin, is still unofficial (for example, "And with your spirit.") I do not condone this practice by any means, or other major deviations from the current translation (though I definitely understand the impulse behind it), but simply report it as a curiosity. Nonetheless, whatever particular small deviations are present, I am told it still represents an example of dignified liturgy and world-class music, and am glad they have maintained their choral tradition with such scrupulous attention.
