"In regard to your question concerning the nature and character of Baha'i
marriage. As you have rightly stated, such a Marriage is conditioned upon
the full approval of all four parents. Also your statement to the effect
that the principle of the oneness of mankind prevents any true Baha'i from
regarding race itself as a bar to union is in complete accord with the
Teachings of the Faith on this point. For both Baha'u'llah and
'Abdu'l-Baha never disapproved of the idea of interracial marriage, nor
discouraged it. The Baha'i Teachings, indeed, by their very nature
transcend all limitations imposed by race, and as such can and should
never be identified with any particular school of racial philosophy."
118: MARRIAGE, BAHA'I (CONSENT OF PARENTS--DUTY OF ASSEMBLY TO ASCERTAIN
VALIDITY)
"With reference to the matter of the consent of the parents to a Baha'i
marriage: As this is a vital binding obligation, it is the duty of the
Assemblies to ascertain, before giving their sanction, that the consent
obtained has been given freely by the parents themselves."
