Pope Benedict has condemned gay marriage, calling it "pseudo-matrimony" between people of the same sex.
During an address at St. John's Cathedral in Rome, the pontiff said same-sex unions were one of several expressions of what he called "an anarchic freedom" that threatened the future of families. He also condemned artificial birth control and "trial marriages".
Before becoming pope in April, the former Cardinal Joseph Ratzinger led a Vatican campaign against same-sex unions in 2003. The Vatican defines matrimony as a divine union between a man and a woman.
