33 The Christian covenant, much more than that of the old, clearly appears as an agreement based not on slavery or on fear, but as one ratified by that friendship which ought to exist between a father and his children, as one nourished and strengthened by a more generous outpouring of divine grace and truth according to the saying of St. John the Evangelist: "And of his fulness we have all received, and grace for grace. For the Law was given by Moses; grace and truth came by Jesus Christ."(27)
