^Duke University's Relation to the Methodist Church: the basics. Duke University. 2002 [2010-03-27]. Duke University has historical, formal, on-going, and symbolic ties with Methodism, but is an independent and non-sectarian institution...Duke would not be the institution it is today without its ties to the Methodist Church. However, the Methodist Church does not own or direct the University. Duke is and has developed as a private non-profit corporation which is owned and governed by an autonomous and self-perpetuating Board of Trustees.
