Francis,
The pope is used to the use of classical music in the liturgy per South German Catholic tradition. Everyone else, in my view, is missing something quite wonderful. One doesn't have to be a Catholic (and I surely am not) to admire it and understand the benefits of which Benedict writes.
Is there an absolute clear line of delineation? Not this side of heaven as you can see by the confusion about what belongs and what doesn't, but I prefer to lean toward what is absolutely clear.
