The features of the "new World Order" are delineated in the Writings of Bahá’u’lláh and ‘Abdu’l-Bahá and in the letters of Shoghi Effendi and the Universal House of Justice. The institutions of the present-day Bahá’í Administrative Order, which constitute the "structural basis" of Bahá’u’lláh’s World Order, will mature and evolve into the Bahá’í World Commonwealth. In this regard, Shoghi Effendi affirms that the Administrative Order "will, as its component parts, its organic institutions, begin to function with efficiency and vigour, assert its claim and demonstrate its capacity to be regarded not only as the nucleus but the very pattern of the New World Order destined to embrace in the fullness of time the whole of mankind". For additional information on the evolution of this new World Order, see, for example, the letters of Shoghi Effendi published in The World Order of Bahá’u’lláh. 190. O source of perversion! #184 This is a reference to Mírzá Yaḥyá, known as Subh-i-Azal (Morning of Eternity), a younger half-brother of Bahá’u’lláh, who arose against Him and opposed His Cause. Mírzá Yaḥyá was nominated by the Báb to serve as a figure-head for the Bábí community pending the imminent manifestation of the Promised One. At the instigation of Siyyid Muḥammad-i-Iṣfáhání (see note 192), Mírzá Yaḥyá betrayed the trust of the Báb, claimed to be His successor, and intrigued against Bahá’u’lláh, even attempting to have Him murdered. When Bahá’u’lláh formally declared His Mission to him in Adrianople, Mírzá Yaḥyá responded by going to the length of putting forward his own claim to be the recipient of an independent Revelation. His pretensions were eventually rejected by all but a few, who became known as Azalís (see note 177). He is described by Shoghi Effendi as the "Arch-Breaker of the Covenant of the Báb" (see God Passes By, chapter X). 191. remember how We nurtured thee by day and by night for service to the Cause #184 In _God Passes By_, Shoghi Effendi refers to the fact that Bahá’u’lláh, Who was thirteen years older than Mírzá Yaḥyá, had counselled him and watched over his early youth and manhood. 192. God hath laid hold on him who led thee astray. #184 A reference to Siyyid Muḥammad-i-Iṣfáhání, who is described by Shoghi Effendi as the "Antichrist of the Bahá’í Revelation". He was a man of corrupt character and great personal ambition who induced Mírzá Yaḥyá to oppose Bahá’u’lláh and to claim prophethood for himself (see note 190). Although he was an adherent of Mírzá Yaḥyá, Siyyid Muḥammad was exiled with Bahá’u’lláh to Akká. He continued to agitate and plot against Bahá’u’lláh. In describing the circumstances of his death, Shoghi Effendi has written in God Passes By:
