The Master

'Abdu'l-Baha, You are the Servant of God.

You are the Center of the Cause.

You are the Most Great Branch. (repeat all)

~

The Teachings You presented are the Spirit of the Age,

And if we reject them, we're stuck in a cage

Of empty reminders of our material ways.

~

Chorus: Oh, 'Abdu'l-Baha, You are the Mystery of God.

Oh 'Abdu'l-Baha, You are the Master of God's Love, of God's Truth.

"He is, and should for all time be regarded, first and foremost, as the Center and Pivot of Bahá'u'lláh's peerless and all-enfolding Covenant, His most exalted handiwork, the stainless Mirror of His light, the perfect Exemplar of His teachings, the unerring Interpreter of His Word, the embodiment of every Bahá'í ideal, the incarnation of every Bahá'í virtue, the Most Mighty Branch sprung from the Ancient Root, the Limb of the Law of God, the Being "round Whom all names revolve," the Mainspring of the Oneness of Humanity, the Ensign of the Most Great Peace, the Moon of the Central Orb of this most holy Dispensation -- styles and titles that are implicit and find their truest, their highest and fairest expression in the magic name Abdu'l-Bahá. He is, above and beyond these appellations, the "Mystery of God" -- an expression by which Bahá'u'lláh Himself has chosen to designate Him, and which, while it does not by any means justify us to assign to Him the station of Prophethood, indicates how in the person of Abdu'l-Bahá the incompatible characteristics of a human nature and superhuman knowledge and perfection have been blended and are completely harmonized."

"He alone had been accorded the privilege of being called "the Master," an honor from which His Father had strictly excluded all His other sons. Upon Him that loving and unerring Father had chosen to confer the unique title of "Sirru'llah" (the Mystery of God), a designation so appropriate to One Who, though essentially human and holding a station radically and fundamentally different from that occupied by Bahá'u'lláh and His Forerunner, could still claim to be the perfect Exemplar of His Faith, to be endowed with super-human knowledge, and to be regarded as the stainless mirror reflecting His light. To Him, whilst in Adrianople, that same Father had, in the Suriy-i-Ghusn (Tablet of the Branch), referred as "this sacred and glorious Being, this Branch of Holiness," as "the Limb of the Law of God," as His "most great favor" unto men, as His "most perfect bounty" conferred upon them, as One through Whom "every mouldering bone is quickened," declaring that "whoso turneth towards Him hath turned towards God," and that "they who deprive themselves of the shadow of the Branch are lost in the wilderness of error." To Him He, whilst still in that city, had alluded (in a Tablet addressed to Haji Muhammad Ibrahim-i-Khalil) as the one amongst His sons "from Whose tongue God will cause the signs of His power to stream forth," and as the one Whom "God hath specially chosen for His Cause." On Him, at a later period, the Author of the Kitáb-i-Aqdas, in a celebrated passage, subsequently elucidated in the "Book of My Covenant," had bestowed the function of interpreting His Holy Writ, proclaiming Him, at the same time, to be the One "Whom God hath purposed, Who hath branched from this Ancient Root."  To Him in a Tablet, revealed during that same period and addressed to Mirza Muhammad Quliy-i-Sabzivari, He had referred as "the Gulf that hath branched out of this Ocean that hath encompassed all created things," and bidden His followers to turn their faces towards it. To Him, on the occasion of His visit to Beirut, His Father had, furthermore, in a communication which He dictated to His amanuensis, paid a glowing tribute, glorifying Him as the One "round Whom all names revolve," as "the Most Mighty Branch of God," and as "His ancient and immutable Mystery." He it was Who, in several Tablets which Bahá'u'lláh Himself had penned, had been personally addressed as "the Apple of Mine eye," and been referred to as "a shield unto all who are in heaven and on earth," as "a shelter for all mankind" and "a stronghold for whosoever hath believed in God." It was on His behalf that His Father, in a prayer revealed in His honor, had supplicated God to "render Him victorious," and to "ordain ... for Him, as well as for them that love Him," the things destined by the Almighty for His "Messengers" and the "Trustees" of His Revelation. And finally in yet another Tablet these weighty words had been recorded: "The glory of God rest upon Thee, and upon whosoever serveth Thee and circleth around Thee. Woe, great woe, betide him that opposeth and injureth Thee. Well is it with him that sweareth fealty to Thee; the fire of hell torment him who is Thy enemy."

And now to crown the inestimable honors, privileges and benefits showered upon Him, in ever increasing abundance, throughout the forty years of His Father's ministry in Baghdad, in Adrianople and in 'Akká, He had been elevated to the high office of Center of Bahá'u'lláh's Covenant, and been made the successor of the Manifestation of God Himself -- a position that was to empower Him to impart an extraordinary impetus to the international expansion of His Father's Faith, to amplify its doctrine, to beat down every barrier that would obstruct its march, and to call into being, and delineate the features of, its Administrative Order, the Child of the Covenant, and the Harbinger of that World Order whose establishment must needs signalize the advent of the Golden Age of the Bahá'í Dispensation.
