CIC 215 “The sum of your word is truth; and every one of your righteous ordinances endures forever.”1 “And now, O LORD God, you are God, and your words are true”;2 this is why God’s promises always come true.3 God is Truth itself, whose words cannot deceive. This is why one can abandon oneself in full trust to the truth and faithfulness of his word in all things. The beginning of sin and of man’s fall was due to a lie of the tempter who induced doubt of God’s word, kindness and faithfulness.

CIC 218 In the course of its history, Israel was able to discover that God had only one reason to reveal himself to them, a single motive for choosing them from among all peoples as his special possession: his sheer gratuitous love.4 And thanks to the prophets Israel understood that it was again out of love that God never stopped saving them and pardoning their unfaithfulness and sins.5

CIC 708 This divine pedagogy appears especially in the gift of the Law.6 God gave the Law as a “pedagogue” to lead his people toward Christ.7 But the Law’s powerlessness to save man deprived of the divine “likeness,” along with the growing awareness of sin that it imparts,8 enkindles a desire for the Holy Spirit. The lamentations of the Psalms bear witness to this.

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.9 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.10 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.”11
