1406. The Mere Name of Bahá'í Does Not Constitute a Bahá'í
"...the Guardian wishes the Bahá'ís to bear in mind the repeated counsels of the Master that the friends should be on their guard when dealing with Easterners. Not only should they trust no one unless he bears some letter of introduction from his Assembly but also after he is permitted in the Bahá'í group they should be very careful in their dealings with him. This does not mean that they should be unkind to him or have a constant suspicion that would gradually alienate him from the Cause, but to be on their guard lest he misuses their trust. The case of Ahmed Sohrab is a very good example of what an Easterner can do. He thinks to be doing shrewd business when a westerner would consider the act to be deceitful. As Bahá'u'lláh says often in His Tablets the friends should develop a flair wherewith they can detect the good from the evil person. Mere name of Bahá'í does not constitute a Bahá'í. His character also has to be Bahá'í."
