III. THE OLD TESTAMENT
4. The Concept of "Mercy" in the Old Testament
The concept of "mercy" in the Old Testament has a long and rich history. We have to refer back to it in order that the mercy revealed by Christ may shine forth more clearly. By revealing that mercy both through His actions and through His teaching, Christ addressed Himself to people who not only knew the concept of mercy, but who also, as the People of God of the Old Covenant, had drawn from their age - long history a special experience of the mercy of God. This experience was social and communal, as well as individual and interior.
It is significant that in their preaching the prophets link mercy, which they often refer to because of the people's sins, with the incisive image of love on God's part. The Lord loves Israel with the love of a special choosing, much like the love of a spouse,37 and for this reason He pardons its sins and even its infidelities and betrayals. When He finds repentance and true conversion, He brings His people back to grace.38 In the preaching of the prophets, mercy signifies a special power of love, which prevails over the sin and infidelity of the chosen people.
