The community also cites their culture as evidence of their Jewish-Christian heritage, particularly their folk songs first written on palm-leave manuscripts in the 17th century. Many of the historical songs allude to the migrants being of Jewish descent such as the song "Nallor Orosilam" (The Good Jerusalem) which states the migrants prayed at the tomb of the Jewish Prophet Ezra before departing to India. A number of Jewish scholars such as Dr. P.M. Jussay, Dr. Nathan Katz, Dr. Shalva Weil, and Dr. Ophira Gamliel have noted that the Knanaya maintain cultural similarities to the Cochin Jews of India,suggesting historic cultural relations between the two communities.
