Latin America's first gay marriage will take place Tuesday in Buenos Aires, Argentina. The marriage of Alejandro Freyre, 39, and Jose Maria Di Bello, 41, is certain to divide the heavily Roman Catholic nation.

“Our December 1 civil wedding service will launch a new campaign in the coming months in different major cities to allow same-sex couples to do the same,” Freyre told reporters on Friday.

Earlier this month, Judge Gabriela Seijas ordered government officials to allow the two men to marry. Her order only affects the progressive city of Buenos Aires, where gay couples won the right to enter civil unions in 2002. City officials said they would not appeal the court's decision, opening the door to gay marriage for the first time in Latin America.

The ruling could improve the odds for a gay marriage bill currently being debated in the Argentine Congress. If approved, Argentina would become the first Latin American country to legalize gay marriage and only the second country in the Americas, after Canada.

A similar measure introduced in 2007 fueled a backlash from the Roman Catholic Church, which opposes the measure. The church wields huge influence in the country of 40 million. Until 1994, the nation's president and vice president were required by law to be members of the Catholic Church and married.

“Claiming heterosexuality as a prerequisite for marriage is not discrimination,” Archbishop Jose Maria Arancedo of Santa Fe told the paper La Nation.

Lawmakers in Mexico City have also introduced a gay marriage bill. Uruguay, however, is the only nation to recognize gay couples with civil unions. The tiny nation also allows gay couples to adopt and gay men and lesbians can serve openly in the military.
