The Declaration of Independence says that government has one purpose; protecting the unalienable, God-given rights that all human beings posses. In the Declaration states:
That, to secure these rights, governments are instituted among men. [The term "rights" had been defined earlier this way -- "they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness."]The Declaration of Independence makes it clear that government has one purpose; that of protecting the inherent human rights of life, liberty and property (pursuit of happiness).
