Ac 20:7 - Now on the first day of the week, when the disciples came together to break bread, Paul, ready to depart the next day, spoke to them and continued his message until midnight.
Colossians 2: 13 And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses, 14 having wiped out the handwriting of requirements .........16 So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, 17 which are a shadow of things to come, but the substance is of Christ
Ro 6:14 - For sin shall not have dominion over you, for you are not under law but under grace.
Ga 2:21 - I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain."
So God changed the rules between the OT and the NT.
