The Universal House of Justice received your message dated 9 May 2001 proposing a change in the title of the new edition of "Messages to America". We have been asked to respond that it considers "This Decisive Hour: Messages from Shoghi Effendi to the North American Baha'is, 1932-1946" both felicitous and descriptive and is happy to endorse it.
With loving Bahá'í greetings,cc National Assembly of the United States (by email)
