After the era of Faith and the era of Reform, came the era of scepticism, which coincides with the era of classical music. The Christian Civilization of Western Europe remained, not intact or unchallenged, but remained, nevertheless, as the bedrock of all European thought and expression.

His Requiem uses the liturgical texts but does violence to them to satisfy symphonic conventions. The Introit and Kyrie form one movement, which is practically correct since, if they were ever used in a liturgical setting there would be hardly a point in a pause. However, it places a clear priority on musical convention over liturgical.
