""A Treatise of Civil Power in Ecclesiastical Causes: That It Is Not Lawful for Any Power on Earth to Compel in Matters of Religion"" is a book written by the famous English poet and political thinker John Milton. The book is a treatise on the separation of church and state, arguing that it is not lawful for any earthly power to compel individuals in matters of religion. Milton argues that religious belief is a matter of individual conscience and that the state should not interfere in matters of faith. The book was published in 1659, during a period of great political and religious upheaval in England, and is considered one of Milton's most important works of political and religious philosophy. It is a powerful defense of religious freedom and individual liberty, and is still widely read and studied today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
