1) Law of God (10 Commandments) - written by finger of God in stone / for all mankind
Whosoever committeth sin transgresseth also the law:
for sin is the transgression of the law.
1 John 3:4
2) Ceremonial Laws (the 7 feasts that pointed to the Messiah's mission & Sanctuary services) / The "shadow" that was cast upon the earth of the heavenly, as Paul puts it. Literally carried out by the Hebrews yearly & now learned from by the Christians through study of them. / Practicing these ceremonies on earth ended with the cross.
Think not that I am come to destroy the law, or the prophets:
I am not come to destroy, but to fulfill.
Matthew 5:17
3) Statutes of Moses (Judicial Law for the Hebrew nation under a direct theocracy of God) / Christians should learn what is right & wrong from them in the eyes of God, although we don't carry out any of the punishments today for violations. (Common sense would dictate such things as the so-called "dietary" laws under this group should be followed simply because the CREATOR understands what is & isn't healthy better than us.)
These are the statutes and judgments and laws,
which the LORD made between him and the children of Israel
in mount Sinai by the hand of Moses.
Leviticus 26:46
