Several hundred people attended Friday night's rally and prayer meeting here at the Jubilee Christian Center in San Jose. Inside the center, the mood was celebration and change. What these church goers are here to support is Proposition 8, a ban on same-sex marriage.
"Marriage should be between a man and a woman," said a woman.
"When you marry you marry a male and a female. A male and a male is not a marriage," said Chris Zelazo, a teacher.
"The problem is that judges overturned the will of the people," said Tryna Bahl, a Proposition 8 supporter.
For these church members the stakes are high. With Prop 8 they hope to overturn the California Supreme Court ruling that legalized thousands of those marriages last spring.
"This is an outrageous attempt to eliminate an existing right from our Constitution," said Geoff Kors, from Equality California.
Kors is with Equality California an anti-Prop 8 group which is being outspent two to one by "Yes on 8."
"Thieve raised over $25 million, a lot from religious organizations who are trying to buy this election," said Kors.
"This is not a political issue, this is a moral issue. We believe that that voice of the church has to be heard in situations like this," said Lou Engle, from The Call.
Lou Engle is the founder of The Call which has tens of thousands of evangelical Christian members all over the country. He's now mobilizing those members to fight against same-sex marriage nationwide. He believes a victory in California will send a strong message to the rest of the country.
"I think we do see the fruits of a whole culture that is basically turning away from fixed moral standards," said Engle.
Supporters of Prop 8 say they're going to take their message to more mega-churches like this to make sure the measure gets passed.
Anti-Prop 8 workers say they know they have a battle on their hands. They say they believe Californians will not reverse the decision that they say gave them a basic human right.
