The Levellers were nonconformist in religion and advocated for the separation of church and state. The church to their way of thinking was a voluntary associating of equals, and furnished a theoretical and practical model for the civil state. If it was proper for their church congregations to be based on consent, then it was proper to apply the same principle of consent to its secular counterpart. For example, the Leveller 'large' Petition of 1647 contained a proposal "that tythes and all other inforced maintenances, may be for ever abolished, and nothing in place thereof imposed, but that all Ministers may be payd only by those who voluntarily choose them, and contract with them for their labours." The Levellers also held to the idea of self-proprietorship.
