17 December 1922
Blest and beloved ones of `Abdu'l-Bahá!
To have been unable, owing to sad circumstances over which I have had no control, to keep in close and constant touch with you, the beloved children of `Abdu'l-Bahá, since His passing from this world, is to me a cause of sad surprise and deep and bitter regret. To say that ever since the Dawn of a New Day has broken upon me I have in the least felt reluctant or disinclined to enter into relationship with every one of you, or felt indifferent to a Cause which is so close and dear to your hearts, would indeed betray every sentiment of love and fellowship which animates every one of us in our servitude to His Holy Threshold. It was rather my utter exhaustion, my profound feelings of sorrow, the overwhelming sense of my own position and responsibilities and the extreme pressure of work that have caused me to maintain such a long silence and seem forgetful of those brave and valiant lovers of the Master in that land.
Of the thoughts that sustained and comforted me during my hours of restful retirement was the realization, never dismissed from my mind, that in the German friends the Master will surely find loyal and grateful children who will repay the tender love and paternal care which He had for them with a devotion and service, so profound and lasting that will prove worthy of the many blessings that have been theirs in the past.
The news of your most spiritual gatherings, since the Great Plan of the Master as revealed in His Testament has been unfolded to our eyes; the formation and functioning of the National Body with efficiency and harmony; the extension of your activities; the widening of your correspondence; the generous and spontaneous help you have extended us in connection with our difficulties in the Holy Land and above all the spirit of ready devotion and ever-increasing zeal which is back of it all--these are sweet thoughts that cheer the bereaved Ladies of the Holy Household and encourage here and abroad the many friends who look forward to the hour when all the Master has promised His friends in Germany will come to be fulfilled.
Having returned to the Holy Land with a renewed vigour and a refreshed spirit, I shall not fail with the help of the Master to do my part in enabling you to carry on further and still further the Glorious Standard of Bahá to the very heart and uttermost confines of Germany and thus hasten the Day when the Spirit of Faith and Peace as revealed in the Cause of Bahá'u'lláh will fill the world and the darkness of strife be no more.
In sweet remembrance at the Three Holy Shrines of your labours of love for His Cause, I am and remain your brother and coworker in His service.

Important Letters from Shoghi Effendi and Bahaeyeh Khanum, the Greatest Holy Leaf
Photograph of the original letter written by Shoghi Effendi and translation of some, sent to the STAR OF THE WEST by his honor Mirza Hadi Shirazi, the noble father of Shoghi Effendi, through Dr. Zia M. Bagdadi. This photograph and the following original letter (from the Greatest Holy Leaf) reached this country after the same recently sent out by the National Spirtual Assembly to the Assemblies throughout America:

He Is God!
This servant, after that grievous event and great calamity—the ascension of His Holiness Abdul-Baha to the Abha Kingdom—has been so stricken with grief and pain and so entangled in the troubles (created) by the enemies of the Cause of God, that I consider my presence here, at such a time and in such an atmosphere, is not in accordance with the fulfillment of my important and sacred duties.
For this reason, unable to do otherwise, I have left for a time the affairs of the Cause, both at home and abroad, under the supervision of the Holy Family and the headship of the Greatest Holy Leaf—may my soul be a sacrifice to her—until, by the Grace of God, having gained health, strength, self-confidence and spiritual energy, and having taken into my hands, in accordance with my aim and desire, entirely and regularly the work of service, I shall attain to my utmost spiritual and aspiration.
The servant of His Threshold, (April, 22) (Signed) SHOGHI
Letter from the Greatest Holy Leaf, Bahaeyeh Khawwm, sent to the Editors of the STAR OF THE WEST:
He Is God!
To the servants of the Blessed Beauty and the dear friends of His Holiness Abdul-Baha!
Although the hearts of the people of Bahá are intensely burning on account of the great calamity (of the ascension of Abdul-Baha), and the sobbing and sighing of the friends have reached the ears of the Supreme Concourse and the Hosts of Holiness in the Abha (Most Glorious) Paradise, yet, because this day is the day of service and this hour is the hour of diffusing the fragrances, the friends of God must, like a bright flame, arise in service to the Cause of God and surpass one another (in service). They should be like penetrating meteors, expelling every disloyal covenant-breaker, in order that in the Preserved Tablet of God, they may be recorded with the group who has fulfilled the Covenant and Testament of God.
His Holiness, the Guardian of the Cause of God, the Primal Branch, the joy of the people of Baha—Shoghi Effendi—because of this great calamity, most painful event, infinite sorrow and the severity of the effect upon himself—has desired to travel for several days, that he may regain his health and have rest. Then he will return to the Holy Threshold, arise in service to the Cause of God and perform his duties.
According to a letter written by his own hand, which is enclosed, he has appointed this prisoner to supervise and manage the affairs of the Cause, through consultation with the Holy Family, during his absence. Therefore, this perishable one, temporarily, has organized an assembly to act according to the advice of the souls who were appointed and nominated by him—His Holiness Shoghi Effendi.
I am hopeful, that during the period of his absence, the friends of God and the maid-servants of the Merciful may show forth great efforts in the progress of the Cause of God, and the Cause of God may spread rapidly.
Verily, He is Compassionate and Merciful to His Servants.
(Signature and seal) BAHAEYEH.

The cablegrams concerning the declaration of Ruhi Afnan a Covenant-breaker include one from December 13, 1951 titled "Old and New Covenant-Breakers" where Shoghi Effendi says, "Evidences multiplying attesting Ruhi's increasing rebelliousness, efforts exerted my eldest sister pave way fourth alliance members family Siyyid Alí involving marriage his granddaughter with Ruha's son and personal contact recently established my own treacherous, despicable brother Riaz with Majdi'd-Din, redoubtable enemy Faith, former henchman Muhammad-'Ali, Archbreaker Bahá'u'lláh's Covenant. Another cablegram sent May 17, 1953, titled "Treacherous Ruhi Afnan", stated "Treacherous Ruhi Afnan, not content with previous disobedience, correspondence with Ahmad Sohrab, contact with old Covenant-breakers, sale, in conjunction with other members of family, of sacred property purchased by Founder of Faith, and allowing his sister to marry son of 'Abdu'l-Bahá's enemy, is now openly lecturing on Bahá'í movement, claiming to be its exponent and is misrepresenting the teachings and deliberately causing confusion in minds of authorities and the local population. Inform National Assemblies."
