It is important to note the distinction between money as an object and a human's obsession with obtaining it which is actually what the original phrase talks about. I'm not a bible thumper, just found this on Wikipedia...
The phrase derives from a saying attributed to Jesus in the Apostle Paul's First Epistle to Timothy in the New Testament: "The love of money is the root of all evil" (1 Timothy 6:10, KJV). The expression is commonly misquoted as simply "Money is the root of all evil". A more accurate rendering from the original Greek may be: "For the love of money is a root of all sorts of evil," (New American Standard Bible).
