Together with a related Ambassador International Cultural Foundation it sponsored both the Ambassador Auditorium concert series and many appearances by Herbert Armstrong in the company of world statesmen and women. The two organizations also jointly sponsored educational projects in Thailand, Sri Lanka, Nepal and Jordan. Armstrong International Cultural Foundation is a non-profit, humanitarian organization sponsored by the Philadelphia Church of God and headquartered on the Herbert W. Armstrong College campus in Edmond, Oklahoma. The two-pronged concept behind all of the foundation's goals and activities is: 1) that man is a unique being, possessing vast mental, physical and spiritual potentials—the development of which should be aided and encouraged, and 2) that it is the responsibility of all men to attend to and care for the needs of their fellow men, a precept professed by the vast majority of religions of the world—appropriately summed up in three biblical words: “Love thy neighbor.” The foundation has sponsored several activities in Jerusalem. In 2006, the foundation began supplying volunteers and aid to Dr. Eilat Mazar's ground-breaking excavation of King David's palace in Jerusalem. It has also helped refurbish Liberty Bell Park in the heart of the city, a project Herbert W. Armstrong had started Successor institutions Several Ambassador graduates and former administrators have led efforts to replicate the school in other settings. When Ambassador closed in 1997, the Worldwide Church of God established the Ambassador Center at Azusa Pacific University. This later gave way to the online Ambassador College of Christian Ministry, which was headed by Ambassador's last president, Russell K. Duke. The graduate program was given then name Grace Communion Seminary. Russell Duke was the president until 2015; Gary W. Deddo was the president until Dec. 2021. Michael Morrison is now the President. Former WCG minister Gerald Flurry established Imperial College in Edmond, Oklahoma, based a great deal on the Ambassador model. To avoid confusion with Imperial College of London, the school is now Herbert W. Armstrong College. One of the campus landmarks is a rock considered to have been used by Herbert W. Armstrong as a "prayer rock" when he lived in Oregon. The campus' Armstrong Auditorium features two Baccarat candelabra purchased from Ambassador Auditorium in Pasadena in 2004, and a bronze swan sculpture (Swans in Flight by Sir David Wynne) purchased from the Big Sandy campus in 2009. In 2015, a second HWAC campus was opened at Edstone, U.K., near Stratford-Upon-Avon.
