Civil authority (also known as civil government) is that apparatus of the state other than its military units that enforces law and order. It is also used to distinguish between religious authority (for example Canon law) and secular authority. In a religious context it may be defined "as synonymous with human government, in contradistinction to a government by God, or the divine government."

Among the first modern experiments in civil government took place in 1636 when Roger Williams, a Christian minister, founded the colony of Rhode Island and Providence Plantations. He sought to create a "wall of separation" between church and state to prevent corruption of the church and maintain civil order as expounded upon in his 1644 book, Bloudy Tenent of Persecution.

Thus three forms of authority may be seen in States:

It can also mean the moral power of command, supported (when need be) by physical coercion, which the State exercises over its members. In this view, because man can not live in isolation without being deprived of what makes him fully human, and because authority is necessary for a society to hold together, the authority has not only the power but the right to command. It is natural to man to live in society, to submit to authority, and to be governed by that custom of society which crystallizes into law, and the obedience that is required is paid to the powers that be, to the authority actually in possession. The extent of its authority is bound by the ends it has in view, and the extent to which it actually provides for the government of society.

Leonidas Donskis, Ph.D., (born on August 13, 1962) is a Member of the European Parliament (MEP), a philosopher, political theorist, historian of ideas, social analyst, and political commentator.

As a public figure in Lithuania, he acted as a defender of human rights and civil liberties. In 2004, Donskis has been awarded by the European Commission the title of the Ambassador for Tolerance and Diversity in Lithuania. A center-right politician, he has always been opposed to all extreme or exclusionary attitudes and forms of violent politics, and, instead, has been leaning to liberalism with its advocacy of individual reason and conscience, ability to coexist with democratic programs of other non-exclusive ideologies, and moderation.

Leonidas Donskis was born in Klaipėda, Lithuania. He graduated from Lithuanian State Conservatoire (now Lithuanian Academy of Music and Theater), majoring in philology and theater, and then pursued his graduate studies in philosophy at the University of Vilnius, Lithuania. Having received his first doctorate in philosophy from the University of Vilnius, he later earned his second doctorate in social and moral philosophy from the University of Helsinki, Finland.

 Martin Luther (help·info) (10 November 1483 – 18 February 1546) was a German monk, priest, professor of theology and iconic figure of the Protestant Reformation. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He confronted indulgence salesman Johann Tetzel with his Ninety-Five Theses in 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Emperor.

Luther taught that salvation is not earned by good deeds but received only as a free gift of God's grace through faith in Jesus Christ as redeemer from sin. His theology challenged the authority of the Pope of the Roman Catholic Church by teaching that the Bible is the only source of divinely revealed knowledge and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with Luther's teachings are called Lutherans.
