Catechism of the Catholic Church
59 In order to gather together scattered humanity God calls Abram from his country, his kindred and his father's house, 16 and makes him Abraham, that is, "the father of a multitude of nations". "In you all the nations of the earth shall be blessed." 17
60 The people descended from Abraham would be the trustee of the promise made to the patriarchs, the chosen people, called to prepare for that day when God would gather all his children into the unity of the Church. 18 They would be the root on to which the Gentiles would be grafted, once they came to believe. 19
61 The patriarchs, prophets and certain other Old Testament figures have been and always will be honoured as saints in all the Church's liturgical traditions.
