Bahá’ís throughout the world celebrate this day [beginning at sunset] as the Day of the Covenant, the Celebration of the Eternal Covenant between God and Mankind through His Manifestations and Prophets, eternal in the past, eternal in the present, eternal in the future:
“His Holiness Abraham, on Him be peace, made a covenant concerning His Holiness Moses and gave the glad-tidings of His coming. His Holiness Moses made a covenant concerning the Promised One, i.e. His Holiness Christ, and announced the good news of His Manifestation to the world. His Holiness Christ made a covenant concerning the Paraclete and gave the tidings of His coming. His Holiness the Prophet Muhammad made a covenant concerning His Holiness the Báb and the Báb was the One promised by Muhammad, for Muhammad gave the tidings of His coming. The Báb made a Covenant concerning the Blessed Beauty of Bahá’u’lláh and gave the glad-tidings of His coming for the Blessed Beauty was the One promised by His Holiness the Báb. Bahá’u’lláh made a covenant concerning a promised One who will become manifest after one thousand or thousands of years. –`Abdu’l-Bahá, Bahá’í World Faith
“As the Sea”
As the sea swells, so the Covenant remains, promises fulfilled.
Through Abraham the Friend of God, and Moses, Giver
Of The Law; fruited and confirmed in Jesus Son of Mary given
In His Person more–the Love of God–and through His Will,
Submission under God in Hijáz through Muhammad, Seal of Prophets;
From the East, Lord Krishna of The Three, The holiness of Buddha in Purity;
The Fires of Zoroaster from the mountain; security from casuistry
Within the Witness of The Báb, and Justice in Bahá’u’lláh
`gainst the nursery rhymes of sophists
And the worship of Creation over He who did create
The whole with but a single Word, “Be!” Hosts exclaim and expiate
Their cavils at the Word through numbers, and the terror of the tribes.
Their synergies against the tide of history, bow the knee to what they rape,
And call it truth. By God! The earth is weary of their weight.
The Word alone remains; the Covenant alone withstands this dreary freight.
