The new believers should be made to realize...Allegiance to the Faith cannot be partial and half-hearted. Either we should accept the Cause without any qualification whatever, or cease calling ourselves Bahá'ís. The new believers should be made to realize that it is not sufficient for them to accept some aspects of the teachings and reject those which cannot suit their mentality in order to become fully recognized and active followers of the Faith.
(From a letter written on behalf of the Guardian to an individual believer, June 12, 1933: Bahá'í News, No. 80, p. 5, January 1934)
