WASHINGTON, D.C. -- As the Supreme Court considers two major same-sex marriage cases that could change marriage in the United States, religious leaders on both sides of the debate believe they are on God's side of the contentious issue.
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."
This week, the Supreme Court will hear two cases. One will examine the constitutionality of Proposition 8, a law that prohibited same-sex marriage in California, and the other will test the Defense of Marriage Act, the 1996 legislation that forbids the recognition of same-sex marriages nationwide and bars married gay and lesbian couples from receiving federal benefits.
Land and Hall each have actively worked on his side of this debate.
Hall, after taking the reins at the National Cathedral in 2012, decided to marry same-sex couples in the historic church. Land, who has counseled Republican presidents and members of Congress, has written and spoken at length about why same-sex marriage goes against biblical principles.
And although they both believe in the Bible, their opinions on how the text views same-sex marriage are shaped by their views on how literally to read the holy book.
"I come from a tradition that looks at the big story," said Hall, an Episcopalian. "The image of Jesus in the Bible is of someone who really makes everyone welcome, and it is from that perspective that I operate."
Hall acknowledges, however, that the Bible isn't the only guide for this belief.
"Our argument is not entirely scriptural-based," Hall said, after acknowledging passages of the holy book that define marriage as being between a man and a woman. "There is no place in the Bible that I can point to that says Jesus performed a same-sex marriage or anything like that."
In addition to scripture, Hall said, "tradition and reason" anchor his belief that same-sex couples should be allowed to wed. There are about 2 million Episcopalians in the United States.
Land, on the other hand, cites the chapters and verses that guide his views on same-sex marriage.
"The people who take a more conservative view of the Bible and believe that they are under the authority of scripture almost universally oppose same-sex marriage," Land said about people who agree with him.
