Another very disturbing feature of the 16th-century Anabaptist movement was its opposition to paying tithes. This state-church tax was experienced by the poor as oppressive and provoked frequent protests (for example in the peasants’ movement of 1524-1526), but it was foundational to the Christendom system and defended by both church and state with determination and increasing desperation. Anabaptists, in common with other radical groups, rejected the state churches’ approach to tithing as unjust and based on bad biblical interpretation.

Leaders of these groups included Felix Mantz, Conrad Grebel, Simon Stumpf, and Wilhelm Reublin, all of whom Zwingli had an impact on. Hubmaier, the Hutterites, and Thomas Müntzer also opposed the exacting of tithes. The Anabaptists maintained that the New Testament taught nothing about tithing and paints a picture of Christians having all things in common.
