Leaders have included Thomas C. Oden, Maxie Dunnam, Bill Hinson, John Ed Mathison, Karen Covey Moore, William J. Abraham, and James Heidinger. The movement has been very successful in maintaining doctrinal standards and traditional United Methodist positions on theology and practice at the General Conferences in Cleveland (2000), Pittsburgh (2004), and Fort Worth (2008). At the 2008 conference for instance delegates voted to retain language in the Social Creed defining marriage as a union between one man and one woman. They also maintained the traditional teaching, that although homosexuals "are individuals of sacred worth", homosexual practice is "incompatible with Christian teaching." After the 2019 United Methodist General Conference, the denomination became sharply divided over the issue of homosexuality and same-sex marriage. Because of this split, there has been speculation about the UMC separating or dividing into two or more denominations. An exit plan for dissatisfied congregations was passed by the 2019 General Conference and upheld by the Judicial Council (top court of the United Methodist Conference). In addition, there are proposals for annual conferences to take place for the purpose of regular doctrinal evaluation.
