One is a secular governing document.  The other is a sacred set of rules that apply to those who hold the text as sacred.  The Ten Commandments only applies to those who feel that the words of the Bible are inspired by God and profitable for teaching, for reproof, for correction for training in righteousness.  The Constitution in no way prevents me from using the Bible for guiding my life and for believing in the God of the Bible.  It also doesn't allow you to stop me or a Muslim or a Buddhist from believing in the God of our choice.  Never try to misapply what the Constitution lays out as a pathway for governing our great nation.  Such foolishness always fails.
