"The Promised One is come! The Kingdom is God’s, the Mighty, the Gracious, the Forgiving."

"O Pope! Rend the veils asunder. He Who is the Lord of Lords is come overshadowed with clouds, and the decree hath been fulfilled by God, the Almighty, the Unrestrained. Dispel the mists through the power of thy Lord, and ascend unto the Kingdom of His names and attributes. Thus hath the Pen of the Most High commanded thee at the behest of thy Lord, the Almighty, the All-Compelling. He, verily, hath again come down from Heaven even as He came down from it the first time. Beware that thou dispute not with Him even as the Pharisees disputed with Him without a clear token or proof. On His right hand flow the living waters of grace, and on His left the choice Wine of justice, whilst before Him march the angels of Paradise, bearing the banners of His signs. Beware lest any name debar thee from God, the Creator of earth and heaven. Leave thou the world behind thee, and turn towards thy Lord, through Whom the whole earth hath been illumined.

We have adorned the Kingdom with the ornament of Our name, the All-Glorious. Thus hath it been decreed by God, the Fashioner of all things. Take heed lest thy vain imaginings withhold thee, when once the Sun of Certitude hath shone forth above the horizon of the Utterance of thy Lord, the Mighty, the Beneficent. Dwellest thou in palaces whilst He Who is the King of Revelation liveth in the most desolate of abodes? Leave them unto such as desire them, and set thy face with joy and delight towards the Kingdom.

Say: O peoples of the earth! Destroy the abodes of negligence with the hands of power and assurance, and raise up the mansions of true knowledge within your hearts, that the All-Merciful may shed the radiance of His light upon them. Better is this for you than all whereon the sun shineth, and unto this beareth witness He Who holdeth within His grasp the ultimate decree. The Breeze of God hath been wafted over the world at the advent of the Desired One in His great glory, whereupon every stone and clod of earth hath cried out: "The Promised One is come! The Kingdom is God’s, the Mighty, the Gracious, the Forgiving."

-Bahá'u'lláh, The Summons of the Lord of Hosts, pp. 54-57
Tablet to Pope Pius IX

From the Introduction: "The years following Bahá’u’lláh’s arrival in Adrianople witnessed His Revelation’s attainment, in the words of Shoghi Effendi, of "its meridian glory" through the proclamation of its Founder’s message to the kings and rulers of the world. During this relatively brief but turbulent period of the Faith’s history, and in the early years of His subsequent exile in 1868 to the fortress town of ‘Akká, He summoned the monarchs of East and West collectively, and some among them individually, to recognize the Day of God and to acknowledge the One promised in the scriptures of the religions professed by the recipients of His summons. "Never since the beginning of the world", Bahá’u’lláh declares, "hath the Message been so openly proclaimed."
