Zoroastrians believe that the world is a battleground between good and evil. It is the duty of everyone to fight against evil, both on a spiritual and physical level. Zoroastrians believe God created the universe and created humanity. In this way they see themselves to be fellow workers in this struggle.
Two types of time
Zoroastrianism divides time into two types: weekly and daily. The former is the sacred time of day while the latter is the period reserved for the dead. Zoroastrians believe that the dead are able to influence the living. These spirits can bring luck and prosperity or hardships and sickness. They offer offerings to these spirits in the form of wine, milk, pomegranates, quinces, and sometimes special animal sacrifices.
One
Zoroastrianism refers to a religion that emphasizes one God. Although its beliefs may be similar to Christianity, it does not believe in a universal God. The Hebrew people were the first to develop the idea of one God over a thousand year before Zoroastrianism was established. The prophet Isaiah spoke of Christ's virgin Birth in 701 BC. This is a century earlier than Zoroastrianism.
Purity
Zoroastrianism is a strong believer in purity. It is the belief that Ahura Mazda was created perfectly and we should respect that. In practice, this is the Zoroastrians' refusal to have their bodies cremated or buried. Instead, they laid their dead bodies at the Tower of Silence. Here, vultures ate them.
Goodness
Zoroastrianism's central concept is that of goodness. Zarasthura, the founder of Zoroastrianism taught his followers to follow the threefold path. This path is analogous to the "law of love" in Christianity, which teaches the importance of seeking to make wise decisions according to God's intentions. Zoroastrianism focuses on goodness, not just the pure good. Its doctrines can be found in many different religions, despite its similarities to Christianity.
