Pioneer....I also very much enjoy Gregorian chants. There is nothing hypocritical about appreciating the beauty of trained voices. I also enjoyed our recent time at the Louvre. The art of Christians (or Egyptians, Buddhists, Muslims etc.) is still art. Humanists have a much easier time with this than Fundamentalists (of any brand). Believers far too often take what is beautiful and declare it ugly.
It's not hard to see why the Romans thought of Christians as "haters of humankind".
