August 30

Bahá'ís should obviously be encouraged to preserve their inherited cultural identities, as long as the activities involved do not contravene the principles of the Faith. The perpetuation of such cultural characteristics is an expression of unity in diversity. Although most of these festive celebrations have no doubt stemmed from religious rituals in bygone ages, the believers should not be deterred from participating in those in which, over the course of time, the religious meaning has given way to purely culturally oriented practices. For example, Naw-Rúz itself was originally a Zoroastrian religious festival, but gradually its Zoroastrian connotation has almost been forgotten. Iranians, even after their conversion to Islam, have been observing it as a national festival. Now Naw-Rúz has become a Bahá'í Holy Day and is being observed throughout the world, but, in addition to the Bahá'í observance, many Iranian Bahá'ís continue to carry out their past cultural traditions in connection with this Feast. Similarly, there are a number of national customs in every part of the world which have cultural rather than religious connotations.
