Basic teachings and Beliefs of Yezidism: Yezidi beliefs are a complicated mixture of Islamic and Zoroastrian beliefs, with Gnostic, Jewish, and Shamanistic elements. Worship centers around Angels (Malek is from the Arabic word for 'angel'), the most important of which is named Melek Taus, or the "Peacock Angel," also known as Lucifer. Lucifer plays a different role in Yezidism, where he is considered the chief Archangel, and the creator of the material world. In Yezidi belief, Lucifer is not a fallen angel, or the enemy of God. In Yezidi cosmology, the universal Spirit (the Supreme deity) created a pearl, which became broken after a period of forty thousand years. Melek, or Lucifer, used the remains of the pearl to create the material world. After this creation, the Spirit created the remaining Angels. Yezidi theology claims that Lucifer was forgiven for his transgressions, and those who revere him are the spiritual elect of humanity. They are forbidden from referring to him as Satan.
Actually there is confusion about just what the Yezidis mean when they can Lucifer “Malak Ta’aus” or “Ta’us Malak” and they will not tell you directly. Sometimes they say Malak means angel or king, and in Semitic languages both are possible depending on vocalization. It is still the worship of what Christians from Armenia to Iraq know as the fallen angel, the devil.
