Christian conservative Scott Lively has predicted “global chaos” if the Supreme Court strikes down state bans on gay marriage.

Lively, the founder of the Massachusetts-based Defend the Family International, made his prediction in a lengthy blog post.

“Absent a miracle from God or [an] unprecedented massive wave of popular protest by America’s Christians (which would be a miracle in itself), the United States Supreme Court will declare a constitutional right to 'gay marriage' by judicial fiat sometime this year,” Lively wrote.

“Spiritually speaking, the official endorsement of 'gay marriage' by the most powerful and influential nation on earth, and more importantly the only nation in the history of the world (other than ancient Israel) to be established on a Biblical foundation, is an act of rebellion against God not seen since Noah’s Flood.”

“I expect some sort of severe judgment to fall on America in conjunction with this process. … America will not stand alone in judgment. The coming calamity will almost certainly be a part of some larger act of God's punishment on the entire world.”

“After weeks or months of global chaos, when the nations are sufficiently broken and the peoples of the world desperate for a return to order, a hero will step upon the world stage to end the crisis,” he added.

Lively, who has pushed for laws criminalizing gay sex and previously likened homosexuality to a disease that overwhelms the immune system, recently argued that it's a slur to call him “anti-gay.”

“I strongly object to that characterization,” he wrote. “[I]t is not an honest descriptor but a slur, and its use by the media is an act of complicity in a dishonest and manipulative LGBT political tactic.”

Lively recently announced he's considering a run for Congress.
