Forgive me, but I do not see it the way you do - Don't think of this as correction, but rather another angle...
[...] there is only one Jewish Holy Day that the non-Jewish nations of the earth will be required to celebrate... and that is Sukkot!
First, they are not Jewish Holy Days... YHWH declared them as 'MY Holy Days'. He ordained them, and they belong to Him.
Secondly, they were not given to the Jews, but rather to the Hebrews - a 'Jew' is one of the House of Judah (the tribes of Judah, half of Benjamin, and half of Levi) - There were twelve tribes at Sinai, and participatory in receiving Torah... Those twelve tribes are still necessarily around. Anyone related to them is as bound to Torah as the Jews. Sorry, it's a sticking point for me - So many want to say that only the Jews are obliged to keep Torah...
And lastly, one cannot separate the moedim from Torah (not one jot or tittle)- If the whole world is keeping Torah (which the prophets explicitly declare), the whole world is necessarily keeping the moedim too.
Isa 66:22 For as the new heavens and the new earth, which I will make, shall remain before me, saith the LORD, so shall your seed and your name remain.
Isa 66:23 And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
(e-Sword:KJV)
Now, there are 3 pilgrim festivals, like you indicated, but in the Millennium it will only be Sukkot. It will be to the point that those nations that dont celebrate it, wont get any rain that year.
[Only be] According to whom? I will grant you that Sukkot is mentioned with exacting specificity, but that does not exclude the rest. In fact Ezekiel 45 mentions Passover with specificity too... To find Shavuot will take some digging. Yet again, I will rest on the facts that Torah is forever, the moedim are forever, and if all the world is keeping Torah, they will all be keeping the moedim (to include the weekly Sabbath) too.
Considering that we are talking about the Millennial Kingdom, that all the prophecies of the Holy Days will be fulfilled...
Except, of course the things the prophets declare about the Holy Days within the Kingdom... : )
I always thought it was kind of funny the requirement for celebrating Sukkot. I just wonder if Sukkot happens to be the birth date for the King of Kings, it would make sense to celebrate, wouldnt it?
Perhaps, because the whole world has been getting it wrong all these years... He saw that coming and was miffed : D But really, birthdays are not celebrated by the Hebrews... That is a western/pagan thing... but it is the day in which he came to tabernacle among us - It may well be the day that He comes again!
Thanks. It has given me a lot to think about!
Did not that ended when after Jesus died on the cross, the veil of the temple ripped in two?
That means that the Kingdom of Heaven was made open for ALL peoples by God Himself.
