I can summarize all long posts. No thread has helped find the truth, each person ends with the same belief.
Some believe some scriptures are not for us and some all scriptures are for us.
Some believe only love is to be listened to for law, some that all law should be listened to.
Some believe the epistles speaks against using rituals to explain Christ, and some believe epistles all speak against all of Moses to explain Christ.
Some believe the OT is good to study to know Christ, and some believe that Christ did away with much of what the OT teaches.
Some believe that if you don’t agree with all they say about law, OT, etc., then you don’t believe in Christ and they are out to get these people against God, and they have an arsenal of scripture they use. You could make a list of like: under grace not law, and on the other side: to love is to obey.
Whichever side you are on, reading the posts won’t help to clear up what scripture says about these things.
