Ritual is to religion what the music of an opera is to the libretto: ostensibly a means of interpretation, but actually a means of concealment. The Presbyterians made the mistake of keeping the doctrine of infant damnation in plain words. As enlightenment grew in the world, intelligence and prudery revolted against it, and so it had to be abandoned. Had it been set to music it would have survived—uncomprehended, unsuspected and unchallenged.
