The Inaugural Address is the speech by an elected American President just after he is sworn into office on January 20th by the Chief Justice. The Twentieth Amendment advanced the date for the new president to take office from March 4th to January 20th, in order to reduce the lame duck period.
Here are some quotes from past Inaugural Addresses:
President Franklin Delano Roosevelt (1945): "Almighty God has blessed our land."
President Harry S Truman (1949): "We believe that all men are created equal because they are created in the image of God."
President Dwight Eisenhower (1953): "This is the work that awaits us all, to be done with bravery, with charity, and with prayer to Almighty God."
President John F. Kennedy (1961): "The rights of man come not from the generosity of the state but from the hand of God."
President Lyndon B. Johnson (1965): "The judgment of God is harshest on those who are most favored."

President Jimmy Carter (1977): "'What does the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God.'"
President Ronald Reagan (1981): "With God's help, we can and will resolve the problems which now confront us. And after all, why shouldn't we believe that? We are Americans."
President George H.W. Bush (1989): "I have just repeated word for word the oath taken by George Washington 200 years ago, and the Bible on which I place my hand is the Bible on which he placed his."
