As to the religion of the Sabaeans, very little is known
about the origins of this religion, though we Bahá'ís are certain of one thing,
that the founder of it has been a divinely-sent Messenger. The country where
Sabaeanism became widespread and flourished was Chaldea, and Abraham is
considered as having been a follower of that Faith.

November 1939 written on behalf of Shoghi Effendi to an individual believer;
