The Bah ' 's believe in an essential unity of the great religions of the world. However, this does not mean they believe the various religious creeds and doctrines are identical. Rather, they view all religions as having sprung from the same spiritual source. The social and outer forms of different religions vary due to the circumstances at the time that they were founded. Other differences in doctrine and belief can be attributed to later accretions, after the death of the founder.
Every person has an immortal soul.
Unlike everything else in creation, it is not subject to decomposition. At death, the soul is freed to travel through the spirit world. In many ways, they were a century or more ahead of many other faiths. Followers are heavily involved in promoting these concepts today. Also, unlike many other religions, Bah ' s view scientific inquiry as essential to expand human knowledge and deepen their members' faith.
