On the same day next week that Gov. Pat Quinn signs the same sex marriage bill in Chicago, Springfield Illinois Bishop Thomas Paprocki will offer "Prayers of Supplication and Exorcism in Reparation for the Sin of Same-Sex Marriage."
The event will take place at the Cathedral in Springfield on Nov. 20.
He's inviting other religious leaders and the laity of the ceremony.
The press release, posted on the Springfield Diocese web site, says "the context for this prayer service may be understood by recalling the words of Pope Francis when he faced a similar situation as Archbishop of Buenos Aires in 2010."
The Pope, who was then referred to as Cardinal Jorge Mario Bergoglio, wrote that an Argentinian plan to redefine civil marriage in that country would "gravely harm the family."
Paprocki says that "since same-sex marriage is contrary to the plan of God, those who contract civil same-sex marriage are culpable of serious sin."
He also noted "politicians who enacted civil same-sex marriage legislation are 'morally complicit as co-operators in facilitating this grave sin."
He says it's "scandalous that so many Catholic politicians are responsible" for this legislation.
The Catholic Diocese of Springfield in Illinois encompasses 130 parishes in 28 counties in central Illinois.
