127. Obedience to the National Spiritual Assembly is the Basis for Unity
"...the Guardian wishes me to again affirm his view that the authority of the National Spiritual Assembly is undivided and unchallengeable in all matters pertaining to the administration of the Faith ... and that, therefore, the obedience of individual Bahá'ís, delegates, groups, and assemblies to that authority is imperative, and should be whole-hearted and unqualified. He is convinced that the unreserved acceptance and complete application of this vital provision of the Administration is essential to the maintenance of the highest degree of unity among the believers, and is indispensable to the effective working of the administrative machinery of the Faith in every country."
