It makes a wrong distinction in order to continue to work at the 10 commandments.
Who was ever under "Levitical" law? Only the Levites were under the Levitical Law. If you want to try to separate it from all the rest of the law. But it isn't to be separated. Otherwise Paul would have been more specific on what Law he was talking about. Such as he did in 2 Corinthians 3.
Hebrews 7:11 If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
The people didn't receive a Levitical law. The levites received the Levitical law. The people received the whole law coming from the 10 commandments.
The people were ruled by the Levitical Law and were subject to its punishments.
