Definition of "prophethood"

They are all invested with the robe of prophethood, and are honored with the mantle of glory.

1935, Shoghi Effendi, Gleanings from the Writings of Bahá’u’lláh‎, translation of original by Bahá’u’lláh

There is no doubt whatever that such souls were prophets, for the mission of prophethood is education, and these wondrous souls trained and educated mankind.
