"...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.
