The genealogical blood lines pertain only to the Greater Covenant, and are only incidental in the Lesser. The reason is very simple: most of the prophecies of the Manifestations to come are interlaced with genealogy, and if you subtract this you destroy one of His chief claims to prophethood.

No regarding, the Primacy, the Primal Branches, the Moons to the Manifestations' suns: This centers around the term that you quoted, "First Born". In Exodus 4:22 (the second book of the Bible - this was given very early) we read, "Thus saith the Lord, Is-ra-el is my son, even my firstborn..." Every Hebrew proper name has a translatable meaning, and Israel (according to my Bible Dictionary, the Concordance, etc.) Means, "He who walks with God," "Ruling with God," "Prince of God," and "Who prevails with God". This is a spiritual sonship and has nothing to do with blood lines. With Krishna it was Arjuna, with Moses - Joshua, with Zoroaster - Ahura Mazda, with Buddha - Annanda, with Christ - Peter, with Mohammed - Ali, with the Báb - Quaddus, and with Bahá'u'lláh - `Abdu'l-Bahá (the only one, incidentally, who was a son at all). I know you have heard a lot about the Primacy of Peter, so revered by the Catholic Church that they adopted hi as first pope. With Bahá'u'lláh it meant a New Covenant - the Lesser, and `Abdu'l-Bahá was appointed as its center because it is evident that he was ultimately spiritually qualified. When `Abdu'l-Bahá delineated the Guardianship and how it was to be perpetuated he also made spirituality of prime necessity!

I can give your further proof positive of this in the following: Cain was the first born biologically, he was the tiller of the soil, the materialist, and (he) slew Abel who was the prototype of the Manifestation - the good shepherd. The blessing was taken from Cain, and the line went down not from him but through Seth, his younger brother. Esau was the first born, but he sold his birthright to his brother Jacob, and the 12 tribes of Israel sprang from him. His son Joseph crossed his hands upon his death bed and gave his blessing not to the elder Manasseh, but the second son Ephraim. Then there was the Beloved David, in whose name many of the prophecies of the Lesser Covenant are given, and from whom the Gospel writers made great effort to prove the descent of Jesus. He was the youngest son of the famous Jesse, but received perhaps the greatest glory of all because of his devotion to God. There are undoubtedly more, but these are all I can think of at the moment. All of this in spite of the Hebrew Law that the eldest is to receive the blessings and most of the material inheritance. It is undoubtedly clear that the first born in religious terminology refers to the first to recognize and remain faithful to God.

You will note that the first clause of the second paragraph of the will (`Abdu'l-Bahá's Will and Testament) says, "...upon that primal branch of the Divine and Sacred Lote Tree" ...SINGULAR; then the paragraph goes on to mention the Twin Holy trees and the Twin surging Seas. Can we say with any honesty at all that `Abdu'l-Bahá was not also a Spiritual Son of the Báb as well as Bahá'u'lláh, and was not guided by Him and flourished under this guidance? We must remember that he passed on this double guidance to the Guardianship! To me, it is clear and always has been that `Abdu'l-Bahá was the First Born, the Primal Branch, regardless of biological incident. Muhammad Ali never did measure up.
