The writer of Hebrews was consistent with the Father and Jesus
“You have loved righteousness [the opposite of lawlessness according to Paul] and hated wickedness [ἀνομίαν – strongs 458 – lawlessness]; therefore God, your God, has anointed you with the oil of gladness beyond your companions.“ (Hebrews 1:9) This is speaking of Jesus and is a quote of Psalm 45:6-7.
The writer of Heberews says a Sabbath rest remains for God’s people and is something to strive for. Regardless of allegorical interpretation, the text does not suggest abolishment of any kind of Sabbath.
“For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.” And again in this passage he said, “They shall not enter my rest.” Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted, “Today, if you hear his voice, do not harden your hearts.” For if Joshua had given them rest, God would not have spoken of another day later on. So then, there remains a Sabbath rest for the people of God, for whoever has entered God’s rest has also rested from his works as God did from his. Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience.” (Hebrews 4:4-11)
Instruction about washings is listed as foundational along with faith toward God, the resurrection and eternal judgement.
“Therefore let us leave the elementary doctrine of Christ and go on to maturity, not laying again a foundation of repentance from dead works and of faith toward God, and of instruction about washings, the laying on of hands, the resurrection of the dead, and eternal judgment. And this we will do if God permits.” (Hebrews 6:1-3)
“For if we go on sinning [breaking God’s law] deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful expectation of judgment, and a fury of fire that will consume the adversaries. (Hebrews 10:26-27)
