I think there is an argument to be made that the concept of morality arose after the enactment of the 39 Articles, in particular, article 7. Originally the word "moral" merely refers to the residue divine commandments which continue to bind Christians after the civil and ceremonial laws of the Old Testament had passed. This later transmuted into a sort of universal moral order or "kingdom of ends" as Kant puts it.
But even here the Article 7 is actually circumspect about "moral", it merely says that these residue commandments are called morals. What is important are the commandments referred to by the word "moral", not the word itself. I think once the word "moral" is divorced from its original context in the 39 Articles, it becomes unintelligible and we should just abandon the word. Once the word "moral" is no longer used to call those residue parts of the divine commands, what is the point?
