First he manifested Himself to or first parents (Jn 1:3, Rom 1:19-20).
After their sin, God made a covenant with Noah and grouped people in their own lands with their familes, in their nations, and each with different languages (Gen 10:5).
The covenant with Noah remains in force until the universal proclomation of the Gospel (p. 21, para 58, CCC).
God chose Abraham to be "the father of a multitude of nations" to gather together scattered humanity (Gen 17:5).
The descendents of Abraham would be the "trustees" of His promise and are called to PREPARE FOR THE DAY WHEN GOD GATHERS HIS CHILDREN INTO THE UNITY OF the CHURCH (Rom 11:28, Jn 11:52, 10:16).
Later God formed Israel as His chosen people when He freed them from slavery in Egypt and established another covenant through Moses at Mount Sanai by giving His law and so the people would look for the promised Savior, God's Son, Jesus Christ, our Lord. Israel's people were the first to hear the Word of God (Deut 28:10, Ex 19:6).
Through His prophets, God formed his people in the HOPES of SALVATION in the EXPECTATON of a NEW and EVERLASTING COVENANT for all and to be WRITTEN IN OUR HEARTS. We believe that above all, the poor and humble of the Lord will bear this hope. The purest person among His people is Mary (Zeph 2:3, Lk 1:38).
