"In every society, the definition of marriage has not ever to my knowledge included homosexuality. That's not to pick on homosexuality. It's not, you know, man on child, man on dog, or whatever the case may be. It is one thing. And when you destroy that you have a dramatic impact on the quality."

As religion is now practiced and science is now practiced, there is no intersection between the two. That is for certain. And it’s not for want of trying. Over the centuries, many people—theologians as well scientists - have tried to explore points of intersection. And anytime anyone has declared that harmony has risen up, it is the consequence of religion acquiescing to scientific discovery. In every single case.
