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.1

CCC 1867 The catechetical tradition also recalls that there are “sins that cry to heaven”: the blood of Abel,2 the sin of the Sodomites,3 the cry of the people oppressed in Egypt,4 the cry of the foreigner, the widow, and the orphan,5 injustice to the wage earner.6

CCC 2571 Because Abraham believed in God and walked in his presence and in covenant with him,7 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.8 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.9
