The Russian Orthodox Church where anti-gay lawmaker Vitaly Milonov worships was fire-bombed on Sunday.

According to local media, two masked men threw a Molotov cocktail at the Church of Holy Peter the Metropolitan Bishop of Moscow but failed to break the window. Damage was limited to a scorched frame.

“We'll find them and destroy them,” Milonov pledged in a tweet.

Milonov is the author of a St. Petersburg law that prohibits the promotion of “gay propaganda” to minors. He encouraged the federal government to pass a similar law. In June, Russian President Vladimir Putin signed the legislation despite an international outcry. Passage of the law has led to calls for a boycott of the Winter Olympics to be held next year in Sochi.

RIA Novosti reported on Monday that police are looking for the suspects.

Citing the parody religion Pastafarianism or Flying Spaghetti Monsterism, which rails against the teaching of intelligent design in public schools, Milonov, 39, blamed the attack on weak morals in Russia. Roughly six followers of the official religion in Russia on Saturday marched through St. Petersburg wearing pasta strainers on their heads.

“It's a sickly spirit permeating our society,” he told the Komsomolskaya Pravda newspaper. “First they wear pasta strainers and then they torch churches.”
