I'll reiterate:
Oneness of God
I can understand this as something relative to the faith's philosophy. Nothing new here.
Oneness of humanity
"This core belief in oneness calls us to actively root out our prejudices and the systemic inequalities that divide people of different ethnic backgrounds, national origins, genders and social classes."
So, this is simply a call for solidarity among people. Ethical treatment of people from all walks of life is a valid desire and is found in many faiths. Nothing new here.
Oneness of religion
"Humanity’s spiritual, intellectual and moral capacities have been cultivated through the successive teachings of the Founders of the world’s religions—the Manifestations of God. Among Them are Krishna, Abraham, Moses, Zoroaster, Buddha, Jesus Christ, Muhammad and, most recently,
the Báb and Bahá’u’lláh. Each religion originates with God and is suited to the age and place in which it is revealed. In essence, the religion of God is one and whose
progressive revelation is unfolding."
For those religions that do not adhere to "the Manifestations of (a) God" this makes no sense. There are many other gods that the Baha’i Faith is leaving out, most importantly, the god of the left hand path, One's Greater Self. There can never be a Oneness of religion as different religions hold different beliefs and philosophies. As I just mentioned, the Baha’i Faith does not, cannot, recognize the left hand path philosophy of the divine given the tenets of its Beliefs in One God.
That said, the 'goals' of the Baha’i Faith will never be accomplished because it neglects specific other religions.
