Stanley R. Rader (August 13, 1930 – July 2, 2002), was an attorney, accountant, author and, later in life, one of the Evangelists of the Worldwide Church of God, then a Sabbatarian organization, which was founded by Herbert W.

On January 5, 1968, Armstrong, as president, together with the secretary of the corporation, amended its Articles of Incorporation to reflect the change of name to the Worldwide Church of God.

In 1975, therefore, he incorporated the Ambassador International Cultural Foundation (AICF) which was actually funded from the tithe money of members of the Worldwide Church of God.

As a consequence, the AICF transformed Ambassador Auditorium, on the Ambassador College campus, from a church auditorium, in which Saturday Sabbath church services were conducted, into a "Carnegie Hall of the West", and launched a concert series featuring the top names in classical music, jazz, and the performing arts.

The AICF also created a new, glossy, secular, coffee-table, commercial magazine called Quest, with a circulation of several hundred thousand copies.

Additionally, the AICF bought the book publisher Everest House, and funded the motion picture Paper Moon starring Tatum O'Neal.

Rader used his own professional legal accounting practice, and also incorporated new companies in order to conduct profitable business enterprises on behalf of the Worldwide Church of God.

In 1980, Rader wrote a book called Against the Gates of Hell: The Threat to Religious Freedom in America, which was published by the Worldwide Church of God's Everest House corporation.

Although Rader appeared to have won the financial receivership battle, his plan to create the AICF cultural empire had come to a halt.

By the time that Rader died on July 2, 2002, just two weeks after being diagnosed with acute pancreatic cancer, the Worldwide Church of God had terminated its former broadcasts and created a separate ministry for its magazine, which had renounced its previous editorial purpose.
