The Vaiphei people belonged to the Kuki-Chin- Mizo group of the Tibeto-Burman and were scattered throughout Northeast India. Before the advent of Christianity in this region, they practiced an animistic religion. The Vaiphei community remained almost segregated. There was little scope for mixing together with other people of the country. They were left alone to lead a life according to their own ways of life. The paper examines the process of transformation and changes taking place among the Vaiphei community with the advent of Christianity. The Vaiphei are also one of the recognized Scheduled Tribes of India.
