Bouvier's Law Dictionary, Revised 6th Ed (1856):

CIVIL. This word has various significations. 1. It is used in
contradistinction to barbarous or savage, to indicate a state of society
reduced to order and regular government; thus we speak of civil life, civil
society, civil government, and civil liberty
     2. It is sometimes used in contradistinction to criminal, to indicate
the private rights and remedies of men, as members of the community, in
contrast to those which are public and relate to the government; thus we
speak of civil process and criminal process, civil jurisdiction and criminal
jurisdiction.
     3. It is also used in contradistinction to military or ecclesiastical,
to natural or foreign; thus we speak of a civil station, as opposed to a
military or ecclesiastical station, a civil death as opposed to a natural
death; a civil war as opposed to a foreign war. Story on the Const. Sec. 789;
