John McCain on teaching evolution

From his 2005 book “Character is Destiny”:

“Darwin helped explain nature’s laws. He did not speculate, in his published theories at least, on the origin of life. He did not exclude God, for Whom the immensity of time is but a moment, from our presence. The only undeniable challenge the theory of evolution poses to Christian beliefs is its obvious contradiction of the idea that God created the world as it is in less than a week. But our faith is certainly not so weak that it can be shaken to learn that a biblical metaphor is not literal history. Nature doesn’t threaten our faith. On the contrary, when we contemplate its beauty and mysteries we cannot quiet in our heart an insistent impulse of belief that for all its variations and inevitable change, before its creation, in a time before time, God let it be so, and, thus, its many splendors and purposes abide in His purpose.”

CNN: “I believe in evolution,” Sen. John McCain said. “But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also.”

Barack Obama on teaching evolution

Media Bistro: “It’s not ‘faith’ if you are absolutely certain,” Obama said, noting that he didn’t believe his lack of “faith” would hurt him in a national election. “Evolution is more grounded in my experience than angels.”

Another quote from Barack Obama on evolution:

Q: York County was recently in the news for a lawsuit involving the teaching of intelligent design. What’s your attitude regarding the teaching of evolution in public schools?

A: “I’m a Christian, and I believe in parents being able to provide children with religious instruction without interference from the state. But I also believe our schools are there to teach worldly knowledge and science. I believe in evolution, and I believe there’s a difference between science and faith. That doesn’t make faith any less important than science. It just means they’re two different things. And I think it’s a mistake to try to cloud the teaching of science with theories that frankly don’t hold up to scientific inquiry.”
