What is the relationship between Jewish Festivals and Shabbat?
What does it mean that the Afterlife will be completely Shabbat?
What does it mean that, in the Afterlife, there won’t be eating or drinking?
Why is the Afterlife called the Garden of Eden?
What does it mean that, in the future, all Festivals will end except Purim?
What does it mean that, in the future, Tisha’ be’Av will become a holiday?
I once joked: ‘A book that doesn’t discuss Free Will cannot be Jewish, and a speech that doesn’t refer to the B’reishith Torah reading can’t be kosher.’
So, let’s start at the very beginning. (According to some, a very good place to start.) Nature started with Six mundane (chol) Days, followed by one holy (kodesh) Day, Shabbat: chol, chol, chol, chol, chol, chol, kodesh.
But humanity was born on the Sixth Day of Creation, the starting point of the Jewish calendar: Rosh haShannah. There are six eternal Festivals mentioned in the Torah. So, contrary to Nature, humanity started on (one of the six of) the Festivals, followed by mundane times: kodesh, kodesh, kodesh, kodesh, kodesh, kodesh, chol. What’s that relationship?
Shabbat starts with the two Blessing of the Kiddush and ends with the four Blessings of Havdalah. The Festivals start with a handful of Blessings and end with the two blessings of Havdalah. What’s that relationship?
Shabbat and Festivals may overlap, or not, but what’s their relationship?
I will suggest how this can all come together on Earth. I don’t know and cannot know how it goes if the end is supernatural. Classical Christianity says this world is not G^d’s world. Only the Afterlife is. Jews disagree.
We are told that Shabbat is a sliver of life in the Afterlife, that Afterlife is eternally Shabbat. Let me suggest that, as part of the Redemption, parallel to what will happen with Shabbat, first, all days will turn into Festivals. Life on Earth will be one, year-round, joyful Jewish Festival. We will also stop dying after G^d slaughters the Angel of Death, as our Sages promised.
Medical scientists are busy ending the main killer illnesses, then will go after aging, then invent rejuvenation, to end up with physical immortality.
Then, scientists will implant into our skins the plant inclusion chlorophyll. We’ll turn green and able to live like green plants, transforming sun rays into energy. We won’t be sex-crazed anymore, so we’ll go about in our green birthday suits unflustered. Back to Paradise. We will also synthesize all vitamins and recycle water, so we don’t need to eat or drink anymore. We’ll be in a ‘different’ world having an eternal Shabbat, no consuming.
Then, Shabbat will join the Festivals. Just as in the Creation Story, the First Shabbat was added to the first Second Day of Rosh haShannah.
Meanwhile, we’re killing humans and the planet (hunger, climate change, wars, murder, substandard healthcare for the masses, etc.), so we might need a Supernatural Redemption not to go the way of the Dodo.
