December 19. On this date in 1982, a letter written on behalf of the Universal House of Justice to the National Spiritual Assembly of Mexico addressed "why the circulation of Bahá'í News should be restricted to Bahá'ís," responding "that "A Bahá'í news bulletin assumes that the reader is a Bahá'í and it would therefore normally contain items which are purely of a domestic nature of no interest to the general public and which, in some cases, may give the wrong impression to those not familiar with the Bahá'í teachings."

360. Bahá'í Newsletters and Bulletins--Why Circulation is Restricted to "Bahá'ís Only"
"In reply to your inquiry of 18th November 1982 about Bahá'í newsletters and bulletins being for Bahá'ís only, we are asked by the Universal House of Justice to quote below from letters written by the Universal House of Justice or at its instruction to other National Assemblies which have asked similar questions.
'With reference to your letter of October 31st asking why the circulation of Bahá'í News should be restricted to Bahá'ís we wish to point out that the same reasons that make it necessary to restrict the attendance at a Nineteen Day Feast to Bahá'ís only apply also to the circulation of Bahá'í Newsletters.
'A Bahá'í news bulletin assumes that the reader is a Bahá'í and it would therefore normally contain items which are purely of a domestic nature of no interest to the general public and which, in some cases, may give the wrong impression to those not familiar with the Bahá'í teachings. However, there is no objection to the friends showing their newsletters to non-Bahá'ís if they so wish or find it useful at times. Furthermore, if the words 'For Bahá'ís Only' which appear on some newsletters are found to be offensive to the non-Bahá'í, there is no requirement for these words to appear on every copy of the newsletter.
'In answer to your query concerning the policy of keeping "Bahá'í News" for Bahá'ís only, the House of Justice instructs us to explain that the circulation of Bahá'í Newsletters is restricted to Bahá'ís because they are vehicles of news that is primarily of internal interest to the friends and the Assembly should be able to write freely to the believers without having to so word the information that it would be easily understandable to a non-Bahá'í reader. In other words, a Bahá'í newsletter is not secret but is an internal journal intended for an informed readership.'"
