Alan Keyes, former US representative to the United Nations, and two-time candidate for the Republican nomination for president, offers an argument in opposition to gay marriage. Keyes bases his argument on a biblically-derived Christian understanding of marriage as sacrament, and a social understanding of heterosexual marriage as a necessary foundation for society. Keyes is introduced by Luke Howe, a UGBC executive and a sophomore in the Carroll School of Management at Boston College. This lecture is sponsored by the Undergraduate Government of Boston College and the College Republicans of Boston College
