It is very similar to what has happened in the United States; 'Abdu'l-Bahá conferred many honours on New York and called it the "City of the Covenant", but this did not prevent Chicago from being chosen as the National Administrative Headquarters owing to its central position in America.
The Stuttgart friends should do all in their power to foster the development of this Administrative Headquarters in Frankfurt, and to ensure its success, as this is what is best for the development of the Faith in Germany. But you can be sure Stuttgart holds a unique position and has received from the Master Himself unique distinction.
It is probable, but not certain, that the first Temple will also, for the same reason, be in Frankfurt. The publishing work, likewise, should be there in the future, but at present its location is for the N.S.A. to decide.
He was very pleased to hear you are requiring all Bahá'ís to withdraw from church membership and similar organizations; he considers your Community the mother community in spirit, and is confident it will continue to lead the way in its exemplary conduct.
You may be sure his loving prayers will be offered for the success of the teaching and administrative work of the Stuttgart believers...
P.S. In the future Stuttgart must naturally have its own administrative headquarters for that city, and he hopes you will soon have found a suitable meeting place.
I was so pleased to receive your most welcome letter. The friends in that centre are very dear and near to me, and I cherish the brightest hopes for their future in the service of our beloved Faith. The Beloved poured forth His manifold blessings upon them and greatly admired their spirit. May His Spirit continue to guide, sustain and bless them in their future services and high endeavors for the promotion of His Faith.
Your most welcome letter of Aug. 21st reached our beloved Guardian after a long delay, as you can see, but brought him great joy. He has instructed me to answer it on his behalf.
He is fully aware of the very sad and difficult conditions under which you are labouring to reestablish the spiritual well-being of the German and Austrian believers, but he feels confident that your great faith, determination and devotion will enable you to achieve your ends and the aid of Bahá'u'lláh is surely vouchsafed you as you serve His Cause and seek to bring enlightenment and inner comfort to the war-weary German people.
