How did judeo-christian beliefs support the idea of equality?

Judeo-Christian Values have a foundational role in America, beginning with the Declaration of Independence: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness..." Since the pursuit of happiness, as Sigmund Freud surmised, is tied to human love and to creative work and play, the principles of American Judeo-Christian Values can rightly be summarized as the honoring of God-given Life, Liberty and Creativity. This seed of American Social Justice was then fleshed out in the U.S. Constitution through reason and common sense, unencumbered by the dysfunctional religious and secular traditions and laws of Old Europe.
