They became the apostles of refined church doctrines to pave way to establish several reformed churches in this southern region of India. Their spiritual revolution widely liberated Christian community from the clutches of traditional Christianity of Kerala by absorbing the spirit of global reformation, but with preserving all its indigenousness. Abraham Malpan, Abraham Marthoma, Sadhu Kochukunju, K E Abraham, K V Simon and others are among those who played the role as bearers of reformation. The present believers’ communities are deeply indebted to these unforgettable visionaries who became the powerful instruments of Lord’s mission.
