The efforts of Barrows and World's Parliament of Religions has visibly left significant legacies for America and its people. In the words of Joseph Kitagawa, "A strong stimulus for the wide acceptance of the study of comparative religion" in America emerged in academic life. While Marcus Braybrooke, President of the World Congress of Faiths, said that "other religions and faiths introduced to Americans other than Christianity has raised the awareness about 'religious plurality' among Americans."Rev Dr Marcus Braybrooke, Writer of over 40 Books Diana L. Eck also sees the first World's Parliament of Religions as one of the first events of the ecumenical movement. It seems to have influenced Christian missionaries abroad and also religious figures from East – Swami Vivekanada, Anagarika Dharmapala, Protap Chunder Mozoomdar, and Soyen Shaku -, towards an appreciation of other religious traditions.
