The other day I heard a very interesting idea about Rosh Hashanah: we say that Rosh Hashanah is the "birthday of Man" because, in reality, instead of celebrating the first day of creation, we celebrate the sixth, when God created Man. That is to say, all of humanity turns 5770 years old this new year.
Therefore, it emerges that not only the Jewish people "have birthdays" or celebrate a holiday, but all human beings in the world can claim the "right to celebrate" this event.
However, in the Torah, the idea of Rosh Hashanah is given to the Jewish people, as if it were a holiday that only we should celebrate, while the rest of humanity does not. Why?
Every creature God created has a specific purpose, as our sages say, for God created nothing in vain. From the mosquito, which the Talmud considers the worst of animals because it only takes (blood) for itself and gives nothing, to stones, plants, and other animals, and even to all human beings, everything has a reason for being in God's master plan. And the simplest proof is that they exist!
The Jewish people, as part of creation, have a special mission, which the Torah defines with the words "to make this lower world a dwelling place for God"; through the use of the entire universe to serve God, we elevate the world and make it a suitable place for the King of all kings, the Holy One, blessed be He, to reside.
And part of this mission is celebrating Rosh Hashanah, which essentially consists of God's coronation as King of the universe. In other words, it is the renewal of the covenant for another year, a new opportunity to fulfill our mission, which begins with accepting that God is the one who defines it. But whether this new opportunity is given (to the entire world) depends on the Jewish people; that is why it appears in the Torah only as a mitzvah for the Jewish people.
Therefore, the idea that "all of humanity has birthdays" can be understood in two ways:
1) It's a way of evading responsibility, that is, trying to delegate to other peoples or at least share the responsibility that God assigned to the Jewish people... after all, we all get older...
2) It is a way of fully assuming the responsibility that God assigned us, being aware that all the peoples of the world are waiting for the Jewish people to sound the Shofar on Sunday at noon, in all the synagogues of the world, crowning God as the only King of the universe and giving everyone another sweet and good year.
Which of the two ways is yours?
May they be registered and sealed for good, for a sweet and good year,
