In science there is a classification of religions in terms of the different classification criteria:
On the presence or absence of God-the Creator of religion is divided into metaphysical and empirical. In metaphysical religions (Judaism, Christianity, Islam, Sikhism, some forms of Hinduism) is that God is the Creator created the universe, including man. In the empirical religions (Buddhism, Taoism, Jainism, Shinto, some forms of Hinduism, Confucianism) the concept of God-the Creator is denied or is of secondary importance. In Buddhism, for example, it is believed that belief or disbelief in a God (the gods) must not be an obstacle on the spiritual path of man.
According to the territorial-ethnic grounds of religion are divided on tribal, national, regional and global. Tribal religion is usually very limited geographically and in fact represented by traditional folk beliefs. National-territorial religion belong to the same people (Judaism) or more, a close friend of the friend of a social (Hinduism). The religions of the world have a great territorially-country coverage and a large number of adherents. The world's religions are Christianity, Islam and Buddhism. It can be noted that Islam was originally the national religion of the Arabs, but in just a few decades became a world religion, gaining space from the Atlantic ocean to India.
On the number of gods religion is divided into a monotheistic and политеистические. In the monotheistic religions, there is only one God - the Supreme God. These include Christianity, Islam, Judaism and Sikhism. Политеистическими religions are pagan beliefs, they worshipped many gods, deities and spirits. Hinduism can be called супрамоно-a theistic religion - his numerous deities are a manifestation of the universal spirit of Brahman.
By the presence of a number of common features religion is divided into Western and Eastern. To the Western religions are Christianity, Islam, Judaism, Sikhism, Zoroastrianism. In Eastern religions - include Hinduism, Buddhism, Jainism, Taoism, Confucianism and Shinto. If we compare Western religion, it is obvious that they have more similarities than differences. Although such differences is given to the critical importance. All Western religions believe in only one life, followed by a Paradise or hell. God is opposed to evil in the face of Satan. Each of these religions considers himself a true and argues that the unbelievers in her face condemnation. All three biblical religions are based on monotheism and dualism, the belief that man is separated from God and God's highest purpose is to attain Paradise. Mainly they all rely not so much on the inner experience or mystical contact, but rather on the sacred rites, faith, labour, which lead man to God.
