J. E. Esslemont - Bahá’u’lláh and the New Era [PDF]

John Ebenezer Esslemont M.B., Ch.B. (1874 – 1925), was a prominent British Bahá'í from Scotland. He was the author of the well-known introductory book on the Bahá'í Faith, Bahá'u'lláh and the New Era, which is still in circulation. He was named posthumously by Shoghi Effendi as the first Hand of the Cause he appointed, and as one of the Disciples of `Abdu'l-Bahá. He was also an accomplished medical Doctor and linguist becoming proficient in western and eastern languages.

The Bahá'í Faith (pron.: /bəˈhaɪ/) is a monotheistic religion founded by Bahá'u'lláh in 19th-century Persia, emphasizing the spiritual unity of all humankind. There are an estimated five to six million Bahá'ís around the world in more than 200 countries and territories.
In the Bahá'í Faith, religious history is seen to have unfolded through a series of divine messengers, each of whom established a religion that was suited to the needs of the time and the capacity of the people. These messengers have included Moses, Buddha, Jesus, Muhammad, and others. For Baha'is, the most recent messengers are the Báb and Bahá'u'lláh. In Bahá'í belief, each consecutive messenger prophesied of messengers to follow, and Bahá'u'lláh's life and teachings fulfilled the end-time promises of previous scriptures. Humanity is understood to be in a process of collective evolution, and the need of the present time is for the gradual establishment of peace, justice and unity on a global scale.
