Satanic 'Black Mass' in Oklahoma opposed by 100,000 A Satanic group is set to verse a "black mass" at the Oklahoma City Civic Center Music Hall this August, but 100,000 people have signed a petition to have the gathering canceled. (Dakhma of Angra Mainyu official website)A screengrab from the homepage of the Satanic group Dakhma of Angra Mainyu. Conservative Roman Catholic organization Tradition, Family and Property (TFP) has forwarded the said petition in the hopes that the Satanic "black mass" could be stopped, just as Catholic protests have prevented a similar ritual from being carried out at Harvard before. The petition calls for the cancellation of the Aug. 15 event, which is deemed as offensive to Catholics all over the world. "With my whole heart and soul, I express full, complete and vehement rejection of the satanic black mass scheduled at the Oklahoma City Civic Center on Aug. 15," the petition reads. "I urge you to cancel this event which offends more than 1 billion Catholics worldwide, 200,000 Catholics in Oklahoma and countless more God-loving Americans. Sacrilege is simply NOT free speech," the petition further states. The upcoming "black mass" will be led by Satanic group Dakhma of Angra Mainyu, which was co-founded by registered sex offender Adam Daniels. The event will involve two rituals — the black mass and the "consumption of Mary by Jai Kali Maa." For TFP Student Action Director John Ritchie, the black mass is a "double attack" against Catholics because it targets both God and the Virgin Mary. He also questioned the nation's direction when the government has now started allowing an event that offends God. As of Apr. 19, the petition has managed to gather 104,700 signatures for the call to have the Satanic black mass in Oklahoma canceled. TFP Student Action is aiming to garner a total of 200,000 signatures for the petition. Meanwhile, Colorado middle schools and high schools have started allowing atheists and Satanists to distribute their literature on April 1. The move came after parents complained about Christians distributing Gideon Bibles to their children in December, The Huffington Post reports. Among the literature handed out to the Colorado students is a coloring book titled "The Satanic Children's Big Book of Activities," created by The Satanic Temple.
