If that is true then why did it seem good to the Holy Spirit to have different burdens for Gentiles than Jews after the cross?
Acts 15:28For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things; 29That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well
EASY PEASY - Acts is the Beginning of the Holy Spirit outpouring.
The Apostles were still being taught and guided by the Lord Jesus Christ thru the Holy Spirit.
Jews were adjusting to trusting in the Lord Jesus Christ and were LEARNING from the LORD that the Law had become OBSOLETE
Both Jews and Gentiles did not need anything from the OT Law concerning observances of rituals which became obsolete.
In Him you were also circumcised with the circumcision made without hands, by putting off the body
[h]of the sins of the flesh, by the circumcision of Christ,
12buried with Him in baptism, in which you also were raised with
Him through faith in the working of God, who raised Him from the dead.
13And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses,
14having wiped out the handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross.
15Having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.
16So let no one judge you in food or in drink, or regarding a
[j]festival or a new moon or sabbaths,
17which are a shadow of things to come, but the
[k]substance is of Christ.
18Let no one cheat you of your reward, taking delight in false humility and worship of angels, intruding into those things which he has
[l]not seen, vainly puffed up by his fleshly mind,
19and not holding fast to the Head, from whom all the body, nourished and knit together by joints and ligaments, grows with the increase that is from God.
20[m]Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations—
21“Do not touch, do not taste, do not handle,”
22which all concern things which perish with the using—according to the commandments and doctrines of men?
23These things indeed have an appearance of wisdom in self-imposed religion, false humility, and
[n]neglect of the body, but are of no value against the indulgence of the flesh.
