Which of the religion worships fire?

Although the term "fire-worshippers" is primarily associated with Zoroastrians, the idea that Zoroastrians worship fire is originally from anti-Zoroastrian polemic. Instead, fire — even in a Fire temple (the Zoroastrian terms are more prosaic and simply mean "house of fire") — is considered to be an agent of purity and as a symbol of righteousness and truth. In the present day this is explained to be because fire burns ever-upwards and cannot itself be polluted. Nonetheless, Sadeh and Chaharshanbe Suri are both fire-related festivals celebrated throughout Greater Iran and date back to when Zoroastrianism was still the predominant religion of the region.

In Vedic disciplines of Hinduism, fire is a central element in the Yajna ceremony, with Agni, "fire", playing the role as mediator between the worshipper and the other gods. Related concepts are the Agnihotra ritual, the invocation of the healing properties of fire; the Agnicayana ritual, which is the building of a fire altar to Agni; and Agnistoma, which is one of the seven Somayajnas. In the Vaishnav branch of Hinduism, Agni or Fire is considered the tongue of the Supreme Lord Narayana, hence all the sacrifices done even to any demigod ultimately is a sacrifice to the Supreme Lord Narayana.
