Brother Boris,
While I agree in principle about "borrowing" from one rite to another (many times proving rather awkward) there have been some significant "cross-fertilizations" between East and West. The use of the Creed in the Mass was first an Eastern practice (for more than 500 years before it became standard in the West). The Gloria in Excelsis came from the East (though from Matins, not Mass, of course). More recently, the Lutherans adopted the fuller Kyrie litany at the start of Mass and it has proven to to be quite fitting. The underlying "shape of the liturgy" (Dix) allows for this borrowing.
Well, you do make a good point.
I didn't know the Creed came into the Western Mass so late. I always assumed the West added it to the Liturgy at the same time the East did.
We sang the Gloria in Excelsis (the Eastern term is the Great Doxology) last night at Bridegroom Matins of Holy Week. (It was one of our "shorter" Holy Week services because it lasted only an hour and forty five minutes. LOL)
Wasn't it Luther Reed of the old
Service Book and Hymnal fame who first came up with the idea of adding an Eastern style Kyrie litany to the Lutheran liturgy? Whoever came up with it idea, I think it was a stroke of creative genius. Rome certainly has not adopted it, nor has Anglicanism either. Yet it does seem to work quite well, and from what I have seen, it seems almost universal practice in most of American Lutheranism now.
I still think Luther Reed's Eucharistic Prayer in the SBH (which he patterned after Chrysostom's) is the single most beautiful Eucharist Prayer Lutherans have ever produced in the English language. I think you could make a good case the Luther Reed was the "Archbishop Cranmer" of American Lutheranism. I think Arthur Carl Piepkorn might qualify for that title too.
Have a blessed Holy Week.
Boris
