READ about Piers Morgan's long career in journalism here.
Coming up on this Christmas Eve, "Piers Morgan Tonight" welcomes Pastor Rick Warren of Saddleback Church to the program.
Welcoming his guest for a primetime interview, Piers Morgan asks the American evangelical Christian pastor and author his opinion on Christianity in America and its influence on politics.
"I think, also, I think during the last decade, the term "Evangelical" became not a theological term, but a political term," says Warren.
"And a lot of people were turned off by the politics," explains Warren. "They say, well, everybody knew that President George [W.] Bush was a 'Evangelical.' They say, 'oh, then you must be in favor of the Gulf War.'"
And although Warren agrees with Morgan that "you've got to separate church and state," he also offers the following counterpoint:
He [Bush] also used his faith to authorize the greatest single health bill in history to - for people with AIDS, PEPFAR, which was the president's emergency plan for AIDS relief," said Warren. "In the last 10 years, I've been in 164 countries. And I have people who say my husband is alive because of President Bush."
Watch the clip, and listen to the interview, as the senior pastor of Saddleback Church – currently the eighth-largest church in the United States – explains why he disagrees with the perspective that Christianity is on the decline in America. Then tune in tonight at 9 as Warren explains the meaning of Christmas.
