Anabaptism
Anabaptism is a belief and practice of a radical Protestent sect in the doctrine that baptism should only be administered to believing adults. The sect or its members were called Anabaptist, and were considered a fanatical sect which arose in Saxony at the time of the Reformation (1520s-1530s), and though it spread in various parts of Germany, came at length to grief by the excesses of its adherents in Münster.
