So worshipping only God is a carnal commandment???
Any worship of God by commandment is carnal and if it is given because of commandment, it is meaningless. Worship only has meaning with God if the one worshipping gives it from the heart and not by command, in which case, no command to do so is necessary.
[Jhn 4:23-24 KJV]
23 But the hour cometh, and now is, when the
true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
24 God [is] a Spirit:
and they that worship him must worship [him] in spirit and in truth.
This is speaking of the laws in the sanctuary under the priesthood, animal sacrifices- fleshy ordinances. Not only using the name of the Lord in a holy manner.
No, it is not speaking of that.
A respective priesthood ministers to specific laws and commandments - all not some of them. When priesthood changes, of necessity, all laws and all commandments that it ministers to - being directly associated and linked to that particular priesthood - must also change. As high priest, Christ's priesthood came after the order of Melchisedec not after the order of Aaron.
Therefore, when Christ alone became the eternal high priest in heaven, all laws and commandments associated to the Levitical priesthood had to change with the change in priesthood, which they did. Being in Heaven, and not in Israel on earth, His priesthood is for everyone chosen by God unto salvation - those from all peoples, and multitudes, and nations, and tongues - chosen by His grace and mercy, not by laws and commandments.
So, your comment about only the fleshy laws and commandments being changed by Christ, is misguided and in error.
[Heb 7:11-18 KJV]
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?
12
For the priesthood being changed, there is made of necessity a change also of the law.
13 For
he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar.
14 For [it is] evident that
our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.
15 And it is yet far more evident: for that
after the similitude of Melchisedec there ariseth another priest,
16 Who is made, not after the law of a carnal commandment,
but after the power of an endless life.
17 For he testifieth,
Thou [art] a priest for ever after the order of Melchisedec.
18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
Christ saves those that come unto God
BY Him, NOT BY LAW. That salvation is everlasting because Christ is the eternal high priest in Heaven.
[Heb 7:25-27 KJV]
25 Wherefore
he is able also to save them to the uttermost that come unto God by him, seeing
he ever liveth to make intercession for them.
26 For such an high priest became us, [who is] holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
27 Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this
he did once, when he offered up himself.
