The Anabaptists, like the medieval evangelical parties whose principles they perpetuated, repudiated, with utmost decision, any sort of interference by the secular authorities in matters of religion and the use of any other than moral means by individual Christians or churches for the enforcement of religious duties. Religious liberty, in its most comprehensive sense, was fundamental with Christians of this type. Many of them erred, however, in refusing to recognize civil government as necessary for Christians and in making holding of civil office a disqualification for church membership.
