traditions are very valuable, for Jewish people there are a bunch of traditions Holidays, Dietary laws, Torah readings, Prayers, religious and many more that they like to do every year/ every few years. for christian people there's baptism, Prayers, going to church every Sunday. And more common ones tons of american's do like thanksgiving, the fourth of July, groundhog day and many more.
If not for traditional rituals, it would become extremely difficult for cultures to retain their distinctiveness. Even everyday rituals have developed in such a way that they have meaning and purpose. ... So, there's no doubt, traditional rituals are still relevant today.
