Every great question of justice in American history, Randy Alcorn notes, concerns the proper application of this principle. Does "all men" include women? African Americans? Native Americans? What is the scope of the community of those who are "created equal" and "endowed by their Creator with certain unalienable rights"? Who counts as one of us?
There is today only one glaring exception. The treatment of human beings before they are born is now the greatest issue of justice in American society. No other class of innocent humans is excluded from basic legal protection and dismembered and killed on an industrial scale (abortion is the leading cause of human death).
Does "all men" include human beings at their earliest developmental stages? Does each and every human being matter—simply on the basis of our shared humanity, irrespective of age, and size, and level of development—or do only some humans matter by virtue of criteria that some of us meet and others do not? No moral, cultural or political question is more important.
The Declaration presented a vision of human equality. We have not yet fully realized it.
