Here are 3 quotations from Baha'i teachings about Zionism, which refute the charge that Baha'is are Zionists:

Shoghi Effendi's statement to the "United Nations Special Committee on Palestine", 14th July 1947, which is still the official position of the Baha'i community today (The Priceless Pearl, p. 286):

"The Bahá'í Faith is entirely non-political and we neither take sides
in the present tragic dispute going on over the future of the Holy Land
and its peoples nor have we any statement to make or advice to give
as to what the nature of the political future of this country should be.
Our aim is the establishment of universal peace in this world and our
desire to see justice prevail in every domain of human society, including
the domain of politics. As many of the adherents of our Faith
are of Jewish and Moslem extraction we have no prejudice towards
either of these groups and are most anxious to reconcile them for their
mutual benefit and for the good of the country.

What does concern us, however, in any decisions made affecting
the future of Palestine, is that the fact be recognized by whoever
exercises sovereignty over Haifa and Acre, that within this area exists
the spiritual and administrative center of a world Faith, and that the
independence of that Faith, its right to manage its international affairs
from this source, the right of Bahá'ís from any and every country of
the globe to visit it as pilgrims (enjoying the same privilege in this
respect as Jews, Moslems and Christians do in regard to visiting
Jerusalem), be acknowledged and permanently safeguarded."

This web page quotes an article from "Star of the West" Baha'i magazine which quotes 'Abdu'l-Baha as saying:

"If the Zionists will mingle with the other races and live in unity with them, they will succeed. If not, they will meet certain resistance. For the present I think a neutral government like the British administration would be best. A Jewish government might come later.
"There is too much talk today of what the Zionists are going to do here. There is no need of it. Let them come and do more and say less.
"The Zionists should make it clear that their principle is to elevate all the people here and to develop the country for all its inhabitants. This land must be developed, according to the promises of the prophets Isaiah, Jeremiah and Zechariah. If they come in such a spirit they will not fail.
"They must not work to separate the Jews from the other Palestinians. Schools should be open to all nationalities here, business companies, etc. The Turks went down because they attempted to rule over foreign races. The British are always in power because they keep fair and promote harmony.
"This is the path to universal peace here as elsewhere -- unity. We must prevent strife by all means. For 6,000 years man has been at war. It is time to try peace a little while. If it fails, we can always go back to war."



"The accusation: That Bahá’ís are agents of Zionism.

The reality: This charge is based on the fact that the Bahá’í World Centre is in Israel. The Bahá’í World Centre was, however, established on Mt. Carmel in the 19th century, long before the State of Israel came into existence, in accordance with the explicit instructions of Bahá’u’lláh, who was exiled there from Iran."
