While some rulers did exhibit tolerance towards different religious beliefs, this was not a widespread phenomenon across northern Europe during the early Reformation. In many regions, rulers actively supported the Catholic Church and opposed Protestant movements, limiting the significant impact of religious tolerance on the spread of Protestantism.

Although peasant movements did occur during this period, they were largely motivated by social and economic grievances rather than explicitly promoting Protestantism. The failure of these movements often led to backlash against reforms, detracting from the overall growth of Protestantism rather than supporting it.

The Catholic Church did attempt to suppress earlier heresies, but its efforts were not uniformly effective. The Reformation gained momentum primarily due to the new ideas and texts being circulated, rather than the Church's historical failures against earlier dissenters. Thus, this was not a primary reason for the rapid spread of Protestantism.
