As always thanks for letting me discuss things with you!
I have a couple of thoughts on this post.

You said.."God gave to the Jews both holy days..." Well Judah was there but also the other 11 tribes.

Leviticus 23 "And the Lord spoke to Moses, saying, 2 “Speak to the children of Israel, and say to them: ‘The feasts of the Lord, which you shall proclaim to be holy convocations, these are My feasts." 44 So Moses declared to the children of Israel the feasts of the Lord.

From here we can see that they are not Jewish but God's, as He says they are His. Now can we in this day and age truly keep this Feast...no, there is no temple or priests to take the required sacrifice to.

With that being said I totally agree when you said.."Just getting outside, away from routine duties and pressures can be a celebration. Perhaps there are friends who join you. Sitting around a campfire in fellowship is pleasant to say the least." There are many many groups around the world that do this every year and the number is getting even larger! Even if you don't think you should have to observe the Feast of Tabernacles I still would encourage you to see if there are any groups in your area that is doing it and go and check it out first hand! If you do, this site will be useful. https://www.119ministries.com/resources/fellowship-finder/

Let me ask you this...do you think we will be keeping the Feast of Tabernacles in the Millennial Kingdom?

Again..always enjoy that we can discuss back and forth from time to time!
