Saddleback Church Pastor Rick Warren, author of "The Purpose Driven Life," talks to Rock Center Special Correspondent Chelsea Clinton about his views regarding love, compassion, acceptance and same-sex marriage.
In this exclusive online excerpt, Warren said that he does not favor the redefinition of marriage. "If you want to use another term, use another term," he told Clinton.
When asked how he felt about civil unions, Warren said, "Civil union might be a term they could use. Yeah, fine. I'm just opposed to redefining marriage."
