Men of ill will

There are several statements in the Sacred Scriptures of our Faith which are related to this general subject, and one in particular is found in "The Dispensation of Bahá'u'lláh", ("The World Order of Bahá'u'lláh", p. 117) as follows: "My fears are for Him Who will be sent down unto you after Me Him Who will be invested with great sovereignty and mighty dominion". When a National Assembly wrote to the Guardian, asking about this reference, the following reply was sent on his behalf.

"...this refers to the Manifestation Who is to come after a thousand or more years, Who like all previous Messengers of God will be subjected to persecutions, but will eventually triumph over them. For men of ill will have been and will always continue to be in this world, unless mankind reaches a state of complete and absolute perfection a condition which is not only improbable but actually impossible to attain."

As you see, the persecutions to which the next Manifestation will be subjected will be carried out, according to the above statement, by "men of ill will" who, alas, "will continue to be in this world". There is nothing in the Writings to support the view that the opposition or persecution will be instigated or inflicted by the Universal House of Justice.
