He it is Who in the Old Testament hath been named Jehovah,
Who in the Gospel hath been designated as the Spirit of Truth, and in the
Qur’án acclaimed as the Great Announcement… But for Him no Divine Messenger would have been invested with the robe
of prophethood, nor would any of the sacred scriptures have been revealed. To
this bear witness all created things.
- Baha’u’llah (Quoted by Shoghi
Effendi in a letter dated February 8, 1934; ‘The Dispensation of Baha’u’llah’)
