The English Independents and the modern Baptists, as well as the Mennonites, may be regarded as the historical continuation of lines of development going back to the Waldensians and the Bohemian Brethren, and passing down through the German, Dutch and Swiss Anabaptists.
Their system is based on literal obedience to the commands of the New Testament, and they have points of similarity both with the Mennonites and with the Dunkards.
Newton is the centre of the settlements of the German-Russian Mennonites, a thrifty people, who immigrated in 1873 and subsequently; Bethel College (opened 1893) is a Mennonite secondary school, and there is a Mennonite hospital.
