In the months leading up to this week's Supreme Court hearings, religious leaders from across the country have held prayer vigils and rallies for their respective causes.

At each event, even those with diametrically opposed views, leaders cite biblical principles as the foundation for their beliefs.

"I believe I am on God's side," Dr. Richard Land, president of The Ethics & Religious Liberty Commission and and opponent of same-sex marriage, told CNN. "I have no question in what God says marriage is."

"I do think we are on God's side because my idea of God is someone that is loving," said the Rev. Gary Hall, dean of the Washington National Cathedral and a proponent of same-sex marriage. "My understanding is that kind of God that loves everyone and wants everyone to live a joyful life."
