418. What is the relationship between the natural law and the Old Law? 1961-1962 1980 The Old Law is the first stage of revealed Law. It expresses many truths naturally accessible to reason and which are thus affirmed and authenticated in the covenant of salvation. Its moral prescriptions, which are summed up in the Ten Commandments of the Decalogue, lay the foundations of the human vocation, prohibit what is contrary to the love of God and neighbor, and prescribe what is essential to it.
