On Perceptions of the Baha'i Faith: Growth and Theology

Here is a snippet from the profile on the Baha'i Faith by the Watchman Fellowship.

...in just 150 years Baha'is have grown to more than 5 million worldwide in 233 countries and territories, with 1,700 Spiritual Assemblies in the United States alone. New growth is occurring at the rate of 5.5% a year worldwide. By comparison, Christianity is expanding at a rate of 2.3% a year. Baha'u'llah's writings have been translated into 802 languages.

Baha'i theology, like Baha'i history, is very difficult to state concisely. The Faith is still relatively new, yet there are hundreds of volumes of written material. Symbolic meaning abounds, and interpretation of many points is in flux. However, in the broad sweep of doctrine many things can be said.
