The Universal House of Justice has received your letter of 11 October 1976 inquiring whether children placed in the home of Bahá'ís for temporary or prolonged care are permitted to attend Bahá'í functions, and we have been asked to inform you that such children may be permitted to attend the Nineteen Day Feasts and other Bahá'í functions, and that no distinction should be made between them and the children of Bahá'ís in this regard.
