Against the background of universal religious experience, in which humanity shares in different ways, God's progressive revelation of himself to the people of Israel stands out. This revelation responds to the human quest for the divine in an unexpected and surprising way, thanks to the historical manner — striking and penetrating — in which God's love for man is made concrete.

It is cooperation with the plan God pursues in history ...to be continued
