Marriage under attack again. The California Supreme Court recently ruled that same-sex marriage was legal in California. Recognizing the importance of marriage to society, the Church accepted an invitation to participate in ProtectMarriage, a coalition of churches, organizations, and individuals sponsoring a November ballot measure, Proposition 8, that would amend the California state constitution to ensure that only a marriage between a man and a woman would be legally recognized. (Information about the coalition can be found at http://www.protectmarriage.com/). On June 20, 2008, the First Presidency of the Church distributed a letter about “Preserving Traditional Marriage and Strengthening Families,” announcing the Church’s participation with the coalition. The letter, which was read in Latter-day Saints’ church services in California, asked that Church members “do all [they] can to support the proposed constitutional amendment.”
