What has Christianity truly contributed to humanity

[Bucky Ball]

Western music really is not the possession of the religious. Many musicians who were not any sect wrote music for the church, as that was the only way to make a regular income.

Right, but I don't think that's true of Bach specifically, which is who I mentioned. He composed masses, "St Matthew's Passion" and others, and was a lifelong keyboardist in church services. Although he did write secular pieces, it's fair to say many of his greatest works were inspired by his faith.

Not sure I agree. He wrote a whole bunch of other (secular) stuff also, (Brandenburg Concertos example), and I have no information if he was "devout" or not, so I don't know what the inspiration was.
