Semitic religions: Semetic religions are religions that originated among the Semites. According to the Bible, Prophet Noah (Peace be upon him) had a son called Shem. The descendants of Shem are known as Semites. Therefore, Semitic religions are the religions that originated among the Jews, Arabs, Assyrians, Phoenicians, etc. Major Semitic Religions are Prophetic religions are Judaism, Christianity and Islam. All these Religions are Prophetic religions that believe in Divine Guidance sent through Prophets of God.
Non-Semitic Religions: The non-Semitic religions are further subdivided into Aryans and non-Aryans Religions :
1. Aryan Religion: Aryan religions are the religions that originated among the Aryans, a powerful group of Indo-European speaking people that spread through Iran and Northern India in the first half of the second Millenium BC (2000 to 1500 BC).
The Aryan religions are further subdivided into Vedic and non-Vedic religions. The Vedic Religions is given the misnomer of Hinduism or Brahmanism. The non-Vedic religions are Sikhism, Buddhism, Jainism, etc. Almost all Aryan religions are non Prophetic religions.

Non-Aryan Religions: The non-Aryan religions have diverse origins. Confucianism and Taoism are of Chinese origin while Shintoism is of Japanese origin. Many of these non-Aryan religions do not have a concept of God. They are better referred to as ethical systems rather then as Religions.

Most Authentic Definition of God in any Religion

The Concept of God espoused by a religion cannot be judged by merely observing the practice of its followers. It is quite common for the followers of many religions to be ignorant of the concept of God in their scriptures. It is therefore better to analyse the concept of God in any religion by referring to its holy scriptures.
