Parable Challenge

Two of my favorite bloggers are having somewhat of a feud. They sent out for friends to join the festivities, and this is how one replied:

Once there were two luthiers who had somewhat of a gentlemanly rivalry concerning their craft. One of the craftsmen, who lived in the north, misted the various parts of his instruments with oil and stain before assembling them. The other, who lived in the south, believed it better to apply the finish by dipping after all the parts were put together. Everyone agreed that both produced very fine-sounding instruments, though their tone differed. Both insisted that their instruments were constructed according to the Book.
