…Manifestations of God have each a twofold station. One is
the station of pure abstraction and essential unity. In this respect, if thou
callest them all by one name, and dost ascribe to them the same attribute, thou
hast not erred from the truth. Even as He hath revealed: “No distinction do We
make between any of His Messengers!” [2:285] For they one and all summon the
people of the earth to acknowledge the Unity of God, and herald unto them the
Kawthar of an infinite grace and bounty. They are all invested with the
robe of Prophethood, and honoured with the mantle of glory. …The other is the
station of distinction, and pertaineth to the world of creation and to the
limitations thereof. In this respect, each Manifestation of God hath a distinct
individuality, a definitely prescribed mission, a predestined Revelation, and
specially designated limitations. Each one of them is known by a different
name, is characterized by a special attribute, fulfils a definite Mission, and
is entrusted with a particular Revelation.
- Baha’u’llah ('The Kitab-i-Iqan’)
