“One Who, not only in the Dispensation of Bahá'u'lláh but in the entire field of religious history, fulfills a unique function.”

'Abdu'l-Baha in New York, 1912

An attempt I strongly feel should now be made to clarify our minds regarding the station occupied by Abdu'l-Bahá and the significance of His position in this holy Dispensation. It would be indeed difficult for us, who stand so close to such a tremendous figure and are drawn by the mysterious power of so magnetic a personality, to obtain a clear and exact understanding of the role and character of One Who, not only in the Dispensation of Bahá'u'lláh but in the entire field of religious history, fulfills a unique function. Though moving in a sphere of His own and holding a rank radically different from that of the Author and the Forerunner of the Bahá'í Revelation, He, by virtue of the station ordained for Him through the Covenant of Bahá'u'lláh, forms together with them what may be termed the Three Central Figures of a Faith that stands unapproached  in the world's spiritual history. He towers, in conjunction with them, above the destinies of this infant Faith of God from a level to which no individual or body ministering to its needs after Him, and for no less a period than a full thousand years, can ever hope to rise.
