The work mounts a sustained argument against using civil power to enforce religious conformity, grounding its case in scriptural interpretation and practical reasoning. It critiques claims that magistrates should punish religious dissent, examines and replies to a contemporary minister's published letter, and offers addresses aimed at lawmakers and general readers. Interleaving theological exegesis, legal and moral reasoning, and polemical rejoinders, the text advocates freedom of conscience and the separation of church authority from state coercion, while outlining a defense of toleration as consistent with Christian principles.
