"The general principle in regard to the marriage of a Baha'i to a
non-Baha'i is as follows:
"If a Baha'i marries a non-Baha'i who wishes to have the religious
ceremony of his own sect carried out, it must be quite clear that, first,
the Baha'i partner is understood to be a Baha'i by religion, and not to
accept the religion of the other party to the marriage through having his
or her religious ceremony; and second, the ceremony must be of a nature
which does not commit the Baha'i to any declaration of faith in a religion
other than his own. Under these circumstances the Baha'i can partake of
the religious ceremony of his non-Baha'i partner.
"The Baha'i should insist on having the Baha'i ceremony carried out before
or after the non-Baha'i one, on the same day."
