Our Mission The Christian Anti-Defamation Commission (CADC) is a not-for-profit 501(c) (3) Education Corporation whose purpose it is to become the first-in-mind champion of Christian religious liberty, domestically and internationally, and a national clearing house and first line of response to anti-Christian defamation, bigotry, and discrimination. More History The idea of the Christian Anti-defamation Commission (CADC) is not new. It has been publicly discussed since at least 1996, and perhaps as early as the 1980s. In October of 1999, General William Hollis, J.D., Ph.D., incorporated the Christian Anti-Defamation Commission.
