Bahá'í literature, like much religious text, covers a variety of topics and forms, including scripture and inspiration, interpretation, history and biography, introduction and study materials, and apologia. Sometimes considerable overlap can be observed in a particular text.

The 'canonical texts' are the writings of the Báb, Bahá'u'lláh, ‘Abdu'l-Bahá, Shoghi Effendi and the Universal House of Justice, and the authenticated talks of ‘Abdu'l-Bahá. The writings of the Báb and Bahá'u'lláh are considered as divine revelation, the writings and talks of ‘Abdu'l-Bahá and the writings of Shoghi Effendi as authoritative interpretation, and those of the Universal House of Justice as authoritative legislation and elucidation. Some measure of divine guidance is assumed for all of these texts.

The Bahá'í Faith relies extensively on its literature. Literacy is strongly encouraged so that believers may read the texts for themselves. In addition doctrinal questions are routinely addressed by returning to primary works.

The Bahá'í Faith ( /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 Abraham, Moses, Jesus, and Muhammad - as well as figures from extra-Abrahamic traditions such as Zoroaster, Krishna, and the Buddha. 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.
