Perhaps Shoghi Effendi writes about himself...

So many misunderstandings arise from the passionate attachment of the friends to the Faith and also their immaturity. We must therefore be very patient and loving with each other and try to establish unity in the Bahá'í family. The differences ... which you describe in your letter he feels are caused by the above and not by enmity to the Faith or insincerity.

(From a letter dated 17 October 1944 written on behalf of Shoghi Effendi to an individual believer)
