Rev. Mendes was an ardent voice in the striving for a Jewish homeland. He was asked by
Theodor Herzl to spread the Zionist cause in America and became one of the founders of the Federation of American Zionists, serving as its president. He was also a member of the Actions Committee of Vienna (1898–99). As he recalls: "Soon after Dr. Herzl began his great movement, Dr. Gaster, chief rabbi of the Spanish &
Portuguese community of England, called upon me in London where I was visiting, saying that Dr. Herzl wished to meet me. They both called the next day and Dr. Herzl asked me if I would undertake to introduce the Zionist movement in the United States. I readily and eagerly consented. Upon my return to the States, I formed the first Zionist association....My interest in Zionism has never been diminished." (
Jewish Daily Bulletin, May 24, 1934) Dr. Mendes saw the establishment of a Jewish homeland as not just a physical goal but also a spiritual one. As he declared at a Zionist rally in Atlantic City in 1933, "Besides upbuilding Palestine, we must promote the ... promulgation of Bible ideals, such as the Brotherhood of Man, the End of War....We Jews must be an element making for good citizenship...we must make the name of the Jew respected....Our destiny is to be altruistic, 'to be a blessing'....There should be on Zion a spiritual center to teach the world the three great R's: Reverence, Righteousness, Responsibility."
