“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

September 20

O thou who hast set thy face towards the Realm on High and hast quaffed My sealed wine from the hand of bounteousness! Know thou that the term ‘Infallibility’ hath numerous meanings and divers stations. In one sense it is applicable to the One Whom God hath made immune from error. Similarly it is applied to every soul whom God hath guarded against sin, transgression, rebellion, impiety, disbelief and the like. However, the Most Great Infallibility is confined to the One Whose station is immeasurably exalted beyond ordinances or prohibitions and is sanctified from errors and omissions. Indeed He is a Light which is not followed by darkness and a Truth not overtaken by error. Were He to pronounce water to be wine or heaven to be earth or light to be fire, He speaketh the truth and no doubt would there be about it; and unto no one is given the right to question His authority or to say why or wherefore. Whosoever raiseth objections will be numbered with the froward in the Book of God, the Lord of the worlds. ‘Verily He shall not be asked of His doings but all others shall be asked of their doings.’  He is come from the invisible heaven, bearing the banner ‘He doeth whatsoever He willeth’ and is accompanied by hosts of power and authority while it is the duty of all besides Him to strictly observe whatever laws and ordinances have been enjoined upon them, and should anyone deviate therefrom, even to the extent of a hair’s breadth, his work would be brought to naught.
