Zoroastrianism is a religion that is mainly practiced in India and Iran, particularly in areas that previously belonged to the ancient Iranian empires. This is among the world's oldest religions.
If you were introduced to a member of this religion, it is important that, above all, you are respectful and open-minded, so that you can engage in successful dialogue. Moreover, you should try to highlight the aspects that both Zoroastrianism and Christianity share. These include a belief in the afterlife, the existence of Heaven and He.ll, monotheism (the belief in a single God), judgement after death, and free will.
