Marriage - Non Bahá’í

As long as both the Bahá’í and the other religious (whatever it may be) ceremony are both performed prior to the consummation of the marriage, we do not mind which ceremony is performed first. It should be left to the individuals concerned to decide among themselves.

Under these circumstances [when two ceremonies are held], the Bahá’í can partake of the religious ceremony of his non-Bahá’í partner. The Bahá’í should insist on having the Bahá’í ceremony carried out before or after the non Bahá’í one, on the same day.

With reference to your question regarding mixed marriages, that is to say between Bahá’ís and non-Bahá’ís; in all such cases the believer must insist that the Bahá’í ceremony should, as far as he is concerned, be performed in its entirety, but should also give full freedom to the other contracting party to carry out the non- Bahá’í rite or ceremony be it Muslim, Christian or otherwise, provided the latter does not invalidate the Bahá’í marriage act. This is the general principle which your N.S.A. should explain to the friends.

As to the holding of the Bahá’í and civil marriage ceremonies on the same day, as the consummation of the marriage should not take place until both ceremonies have been held, a night should not intervene between the two ceremonies.

Further, there is no objection for Bahá’ís to attend religious marriage ceremonies of their friends and relatives or take part in festivities usually connected with these events, provided that in doing so they do not contravene Bahá’í Law. For example, if consuming alcoholic beverages is a part of such activities, the Bahá’ís, of course, would be obliged to refrain from partaking of such drinks.

If the parents of a Bahá’í couple are, for example, Christians, there is no objection to their attending church with their parents and their parents' friends and relations, if their parents so wish, in order to pray for the future of the marriage, but such attendance should not involve any form of marriage ceremony or simulated marriage ceremony.
