This is not correct. New Testament teachings do not REPLACE Old Testament teachings.
sorry but what i meant was that New Testament moral law replaces (not entirely) Old Testament law. it was meant in a moral context. obviously the Old Testament laws from Leviticus and Deuteronomy are for a rising nation focusing on surviving and overcoming, while the New Testament laws are for a spiritual movement, spreading and permeating the world.
it's obvious why obama didn't reference the ten commandments.
