Campaign organizers are aiming to get 1 million Catholics, Mormons, Jews, Muslims, evangelical Christians, Sikhs and Hindus to post lawn signs supporting a state ballot measure to ban same-sex marriage, the Los Angeles Times reported Sunday.

Proposition 8 is aimed at countering a state Supreme Court decision this year that struck down a ban on gay marriage.

"This is a rising up over a 5,000-year-old institution that is being hammered right now," said Jim Garlow, pastor of Skyline Church, an evangelical congregation in La Mesa, Calif.

Susan Russell, a priest at All Saints Episcopal Church in Pasadena, Calif., said not all faith leaders should not foist their views on all Californians.

"But I'll resist to my last breath, vote, e-mail and blog their right to inflict their religious beliefs on the Constitution of the state of California."
