"....O followers of the Son! We have once again sent John unto you, and He, verily, hath cried out in the wilderness of the Bayán
(Bab - Gate): O peoples of the world! Cleanse your eyes! The Day whereon ye can behold the Promised One and attain unto Him hath drawn nigh! O followers of the Gospel! Prepare the way! The Day of the advent of the Glorious Lord is at hand! Make ready to enter the Kingdom. Thus hath it been ordained by God, He Who causeth the dawn to break.
Give ear unto that which the Dove of Eternity warbleth upon the twigs of the Divine Lote-Tree: O peoples of the earth! We sent forth him who was named John to baptize you with water, that your bodies might be cleansed for the appearance of the Messiah. He, in turn, purified you with the fire of love and the water of the spirit in anticipation of these Days whereon the All-Merciful hath purposed to cleanse you with the water of life at the hands of His loving providence.
This is the Father foretold by Isaiah, and the Comforter concerning Whom the Spirit had covenanted with you. Open your eyes, O concourse of bishops, that ye may behold your Lord seated upon the Throne of might and glory.
Say: O peoples of all faiths! Walk not in the ways of them that followed the Pharisees and thus veiled themselves from the Spirit. They truly have strayed and are in error. The Ancient Beauty is come in His Most Great Name, and He wisheth to admit all mankind into His most holy Kingdom. The pure in heart behold the Kingdom of God manifest before His Face. Make haste thereunto and follow not the infidel and the ungodly. Should your eye be opposed thereto, pluck it out. Thus hath it been decreed by the Pen of the Ancient of Days, as bidden by Him Who is the Lord of the entire creation. He, verily, hath come again that ye might be redeemed, O peoples of the earth. Will ye slay Him Who desireth to grant you eternal life? Fear God, O ye who are endued with insight....."
