Former Methodist minister Frank Schaefer discusses the division within the United Methodist Church (UMC) over the issue of homosexuality. Schaefer was stripped of his clerical credentials in December 2013 after a 13-member jury of pastors found him guilty of disobeying church law. The UMC Book of Discipline, which contains the church's laws and doctrines, forbids celebrations of same-sex marriages and asserts that the practice of homosexuality is "incompatible with Christian teaching." Schaefer is now an outspoken activist working to change Methodist policy on gay marriage. This movement within the UMC prompts the question: How do voluntary, private organizations change-or refuse to change- policies about matters that are central to their missions?
