CIC 64 Through the prophets, God forms his people in the hope of salvation, in the expectation of a new and everlasting Covenant intended for all, to be written on their hearts.1 The prophets proclaim a radical redemption of the People of God, purification from all their infidelities, a salvation which will include all the nations.2 Above all, the poor and humble of the Lord will bear this hope. Such holy women as Sarah, Rebecca, Rachel, Miriam, Deborah, Hannah, Judith and Esther kept alive the hope of Israel’s salvation. The purest figure among them is Mary.3

CIC 762 The remote preparation for this gathering together of the People of God begins when he calls Abraham and promises that he will become the father of a great people.4 Its immediate preparation begins with Israel’s election as the People of God. By this election, Israel is to be the sign of the future gathering of All nations.5 But the prophets accuse Israel of breaking the covenant and behaving like a prostitute. They announce a new and eternal covenant. “Christ instituted this New Covenant.”6

CIC 2317 Injustice, excessive economic or social inequalities, envy, distrust, and pride raging among men and nations constantly threaten peace and cause wars. Everything done to overcome these disorders contributes to building up peace and avoiding war:
Insofar as men are sinners, the threat of war hangs over them and will so continue until Christ comes again; but insofar as they can vanquish sin by coming together in charity, violence itself will be vanquished and these words will be fulfilled: “they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more.”7
