Are there any historic Christian documents that provide a comprehensive categorization of the commands of the OT Law / mitzvot using the three categories from the WCF?
And, if so, then as a secondary question: Why is it such a list so difficult to find??
The "threefold division of the law" into the categories of moral, civil, and ceremonial, was standardized in the Westminster Confession of Faith, chapter nineteen, and according to some scholars can be traced, in various forms, as far back as the writings of Barnabas.
This page at GotQuestions.org links the "moral" category with a "mishpatim," and the "ceremonial" category with a "hukkim or chuqqah," apparent references to Judaic teachings. The "civil / judicial" category is said to be a creation of the Westminster Divines.
Efforts to research the words "mishpatim," and "hukkim," "chuqqah," online have quickly led to lots of Hebrew text that I don't understand on Jewish sites, and I'm not sure if the GotQuestions page is correct in connecting the Christian and Jewish categories in the first place.
