I agree. The gentile Christians were not placed under the levitical dietary restrictions
Ac 21:25 As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication.
Nor under levitical calendar
Gal 4:9 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.
Do you honestly believe that Paul would call scriptural commandments of God "weak and beggarly elements"?
What Paul is referring to here is gentiles who wanted to return to worshipping pagan days. The ONLY scriptures Paul had were the books of what we call the "old testament". It would have been blasphemous for him to call the words of the Lord "weak and beggarly elements".
