Catholic League President Bill Donohue has described marrying for love as “one of the most bizarre ideas in the whole world.”

Donohue, an ardent opponent of gay marriage, made his comments during an appearance on cabler Current's Viewpoints.

“This idea of two men getting married is the most bizarre idea in human history,” Donohue said.

“Why is that?” host John Fugelsang asked.

“Well, can we name of a single society or civilization in the history of the world up until yesterday which ever entertained this?”

“But how is that against the teachings of Jesus Christ in any way?”

“Christians have an obligation to follow – particularly Catholics – natural law. That means, for example, everyone knows in their right mind that the whole purpose of marriage is to have a family. It's not about making people happy. It's not about love.”

“Marriage has nothing to do with love.”

“Sure it does,” Fugelsang responded. “In this society it does.”

“It's one of the most bizarre ideas in the whole world. The idea that you fall in love to get married. Usually it's a form of duty,” Donohue said. (The video is embedded on this page. Visit our video library for more videos.)
