The changing of teachers should be neither too frequent nor too much
delayed; moderation is preferable. Holding your meetings when it is the
time of prayer in other churches is not advisable; it would lead to
alienation, since the Baha'i children who have their own Sunday school
would be deprived of it if they tried to attend other Sunday schools.
Moreover, the admission of children of non-Baha'i parents to the school
for Baha'i children is permissible. And if, in this school, an outline of
the fundamental principles underlying all religions be set forth for the
information of the children, it can do no harm.
As the children are few in number, it is not possible to have different
classes and naturally only one is necessary. Concerning the last question
regarding differences among children, act as ye deem advisable.
