CCC 146 Abraham thus fulfills the definition of faith in Hebrews 11:1: “Faith is the assurance of things hoped for, the conviction of things not seen”:1 “Abraham believed God, and it was reckoned to him as righteousness.”2 Because he was “strong in his faith”, Abraham became the “father of all who believe”.3
CCC 288 Thus the revelation of creation is inseparable from the revelation and forging of the covenant of the one God with his People. Creation is revealed as the first step towards this covenant, the first and universal witness to God’s all-powerful love.4 And so, the truth of creation is also expressed with growing vigor in the message of the prophets, the prayer of the psalms and the liturgy, and in the wisdom sayings of the Chosen People.5
CCC 343 Man is the summit of the Creator’s work, as the inspired account expresses by clearly distinguishing the creation of man from that of the other creatures.6
CCC 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.7 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.8 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.”9
CCC 2374 Couples who discover that they are sterile suffer greatly. “What will you give me,” asks Abraham of God, “for I continue childless?”10 And Rachel cries to her husband Jacob, “Give me children, or I shall die!”11
CCC 2570 When God calls him, Abraham goes forth “as the Lord had told him”;12 Abraham’s heart is entirely submissive to the Word and so he obeys. Such attentiveness of the heart, whose decisions are made according to God’s will, is essential to prayer, while the words used count only in relation to it. Abraham’s prayer is expressed first by deeds: a man of silence, he constructs an altar to the Lord at each stage of his journey. Only later does Abraham’s first prayer in words appear: a veiled complaint reminding God of his promises which seem unfulfilled.13 Thus one aspect of the drama of prayer appears from the beginning: the test of faith in the fidelity of God.
CCC 2571 Because Abraham believed in God and walked in his presence and in covenant with him,14 the patriarch is ready to welcome a mysterious Guest into his tent. Abraham’s remarkable hospitality at Mamre foreshadows the annunciation of the true Son of the promise.15 After that, once God had confided his plan, Abraham’s heart is attuned to his Lord’s compassion for men and he dares to intercede for them with bold confidence.16
