The life of Abraham can be found in the Book of Genesis in the Old Testament, Chapters 12-25. His constant obedience to God has earned him the title of "Righteous" and is a wonderful example so that we may offer our own obedience and love to God.
Most know of only this "Forefather" Abraham in the history of mankind, and his famous Gettysburg Address: "Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal..." citation

Through the intercession of our Holy Father among the Saints, Righteous Abraham, O Christ our God, have mercy upon us and save us!
