As regards
the celebration of the Christian Holidays by the believers; it is surely preferable
and even highly advisable that the friends should in their relation to each
other discontinue observing such holidays as Christmas and New Years, and to
have their festal gatherings of this nature instead during the intercalary days
and Naw-Ruz.
(From a letter written on behalf of Shoghi Effendi to an
individual believer, March 19, 1938; compilation: Lights of Guidance)
