Zoroastrians believe that there is no place like the battlefield of good and evil. Everybody has the responsibility to fight evil both spiritually and physically. Zoroastrians believe God created man and is the creator all things. They see themselves as co-workers in this fight.
Two types of time
Zoroastrianism defines time in two ways: weekly and daily. The first type of time is considered the sacred hour of the day. The second is the period that is reserved for the dead. Zoroastrians believe the dead can have an effect on the living. These spirits may bring you prosperity and fertility, or can cause hardships and sickness. They offer wine, milk, pomegranates and quinces as offerings to these spirits.
One God
Zoroastrianism is a religion that focuses on one God. Although its beliefs are very similar to Christianity in many ways, Zoroastrianism's belief system does not hold the same universality. The concept of one God was actually developed by the Hebrew people, more than a thousand years prior to the foundation of Zoroastrianism. The prophet Isaiah spoke of Christ's virgin Birth in 701 BC. This is a century earlier than Zoroastrianism.
Purity
Purity is an important concept in Zoroastrianism. It refers to the belief that the creation of Ahura Mazda is perfect and that we should not defile it. This is what Zoroastrians believe in practice. They have avoided burial and cremation for centuries. They instead bury their bodies at the Tower of Silence where vultures consume them.
Goodness
Goodness is an important concept in Zoroastrianism. Zarasthura was the founder of Zoroastrianism and taught his followers to follow the threefold way. This path is similar to Christianity’s “law of love”, which teaches us to follow God's instructions and to make wise, loving decisions. Zoroastrianism, however, emphasizes goodness and not purely good. Its doctrines can be found in many different religions, despite its similarities to Christianity.
