Is it not clear sacrificial law has been abolished
Ceremonial law is no longer obligatory
There is plenty of room to interpret God's word as promoting rebellion against God if someone is determined to do that, but it is unwise. In Matthew 5:17-19, Jesus said that he came not to abolish the law and warned against relaxing the least part of it or teaching others to relax the least part of it, so you are calling him a liar and disregarding his warning. Likewise, in Romans 3:31, our faith does not abolish God's law, but rather our faith upholds it.
Galatians 4:9–11 (KJV 1900) — 9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? 10 Ye observe days, and months, and times, and years. 11 I am afraid of you, lest I have bestowed upon you labour in vain.
In Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know Him, and in Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so the goal of the law is to teach us how to know God and Jesus, which is the content of God's gift of eternal life (John 17:3). In Galatians 4:8-11, Paul addressed those who formerly did not know God, so he was not addressing those who were formerly obeying God's instructions for how to know Him and were returning to following those instructions, but rather he was addressing those who were not formerly obeying those instructions and who were enslaved to those that by nature are not gods, also known as former pagans. As such, they were not formerly keeping God's holy days and Paul could not have been criticizing them for returning to them, so whatever he was referring to them observing in verse 10 is within the context of paganism.
Colossians 2:16 (ESV) — 16 Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath.
That verse leaves room for two possibilities:
1.) They were not keeping God's holy days, they were being judged by Jews for not keeping them, and Paul was encouraging not to let anyone judge them for not keeping them.
2.) They were keeping God's holy days in obedience to God, they were being judged by pagans because they were keeping them, and Paul was encouraging them not to let any man judge them for not keeping them.
In Colossians 2:16-23, Paul described the people who were judging the Colossians as promoting human teachings and precepts, self-made religion, asceticism, and severity to the body, so they were being judged by pagans, which means that #2 is the case. Those teaching asceticism and severity to the body would not be judging people for refraining from celebrating feasts, but rather they would be judging people for celebrating them. So it is ironic when people try to use this verse as justification for refusing to obey God.
Romans 14:5 (ESV) — 5 One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind.
In Romans 14:1, the topic of the chapter is in regard to how to handle disputable matters of opinion in which God has given no command, not in regard to whether followers of God should follow God's commands, not nothing in the chapter should be interpreted as promoting rebellion against God. For example, in Romans 14:2-3, they were judging and resenting each other based on whether someone chose to eat only vegetables even though God gave no command to eat only vegetables. In Romans 14:4-6, Paul spoke about those who were eating or refraining from eating unto the Lord, so he was speaking about those who esteemed certain days for fasting as a disputable matter of opinion. It has become a common practice the 1st century to fast twice a week and people were judging and resenting each other based on whether they chose to do that even though God gave no command to do that. Paul was not suggesting that we are free to rebel against God's commands to keep the Sabbath holy or to refrain from committing murder, idolatry, adultery, theft, rape, kidnapping, favoritism, or any of God's other commands just as long as we are convinced in our own minds that it is ok to rebel against God, but rather that was only said in regard to things that are disputable matters of opinion in which God has give no command. It is important to distinguish between what is said about following the teachings and options of men and what is said about following the commands of God.
