The bishop of Springfield, Illinois issued a statement:

Scheduled for approximately the same time that Gov. Pat Quinn signs into Illinois law the redefinition of civil marriage, Bishop Thomas John Paprocki will offer “Prayers of Supplication and Exorcism in Reparation for the Sin of Same-Sex Marriage” at the Cathedral of the Immaculate Conception, Sixth and Lawrence streets in Springfield, on Wednesday, Nov. 20, from 4 to 5 p.m. Clergy, religious and laity are invited to attend.

“It is scandalous that so many Catholic politicians are responsible for enabling the passage of this legislation and even twisting the words of the pope to rationalize their actions despite the clear teaching of the church,” he said. “All politicians now have the moral obligation to work for the repeal of this sinful and objectionable legislation. We must pray for deliverance from this evil which has penetrated our state and our church.”

Though I now occasionally will say nice things about Pope Francis, it's important to note that the Catholic Church continues to just absolutely suck.

UPDATE: Slog tipper Corinne points out that the end of this article about the same story includes this terrifying paragraph:

Exorcism is experiencing something of a renaissance in the United States, with the Catholic bishops recruiting dozens of priests to perform the ancient rite. Paprocki is among the bishops leading the recruiting drive.
