Kunnampurathu Varghese Simon (1883–1944) was an Indian preacher, poet, and Bible scholar whose ministry significantly influenced the Kerala Brethren movement during the early 20th century. Born on February 7, 1883, in Edayaranmula, Kerala, to Varghese, a scholar of Hindu Puranas, and Kandama, a poet, Simon displayed exceptional intelligence from a young age, passing a government examination at 13 to become a school teacher, a profession he held for over 20 years. He was baptized in 1895 at age 12 after hearing evangelist Tamil David, marking the beginning of his Christian commitment. In 1900, he married Ayroor Pandalapedika Rahelamma, later known as Ayroor Amma, and they had one daughter. Simon’s preaching career emerged alongside his roles as a teacher and poet, becoming a prominent leader in the Kerala Brethren movement after aligning with its principles in the 1920s, having initially joined the Baptist Church for financial support of his separatist "Viyojithar" congregations. A polyglot fluent in Malayalam, Sanskrit, Tamil, English, Hindi, Telugu, Kannada, Greek, Latin, Hebrew, and Syriac, he authored over 300 hymns and 30 books, including the poetic masterpiece Veda Viharam (1931), which earned him the title "Mahakavi" (Dean of Poets) from the Sahitya Parishad. His apologetic works, such as Prathiyukthi and Satyaprakashini, defended Christianity against Hindu critics. Simon died in early 1944, leaving a legacy as a preacher whose scholarship, poetry, and leadership shaped the Brethren movement in India.
