is there a difference between civil government and human government?

Answer 1

No. Except the one slight difference that a civil government can be through elections; but, the overall concept is the same.

Human government is the concept that simple, flawed humans control the government through inheritance.

Both are related to the combination of church and state ultimately where Human Government was seen (thought to be seen) in the Middle Ages how one insane king would have insane children that would lead on and on and on, until the God government that was meant to be, had deteriorated to the point where it was human government.

The forms of civil government are considered to be of three kinds:
1. Monarchy, which is the dominion of one person, whether called a king, or a duke, or any other title;
2. Aristocracy, or the dominion of the principal persons of a nation; and
3. Democracy, or popular government, in which the power resides in the people at large. It is true that the transition is easy from monarchy to despotism; it is not much more difficult from aristocracy to oligarchy, or the faction of a few; but it is most easy of all from democracy to sedition.

Answer 2

Civil government is more concerned with the survival of the government while human government is more concerned with people.
