The Catholic Church is again in another controversy. This time the ownership of a billion-dollar German media company that has been reported selling some pornographic materials, which is against its philosophy and teachings.

A report from online news provider Worldcrunch.com has revealed that the German company Weltbild, the largest media firm selling books, DVDs, music and more also happens to sell pornographic materials and other erotica.

The report said that although it has been 10 years that a local group had written the Catholic Church authorities about this, no action has been taken to address the situation.

"In 2008, the group sent a 70-page document to all the bishops whose dioceses have shared ownership of Weltbild for 30 years, detailing evidence of the sale of questionable material," Worldcrunch.com said.

It further explained that Wetbild, based in Augsburg, Germany, these days has a workforce of 6,400 and turns over some 1.7 billion euros in revenues. It ranks second to Amazon.com when it comes to its online sales of books and other media-related materials.

Although it has been against the Catholic Church teachings, some 2,500 erotic books are listed on the online catalogue of Weltbild, these include the Blue Panther Books with titles: "Schlampen-Internat" (Sluts' Boarding School). "Vögelbar" (F-kable), and "Anwaltshure" (Lawyer's Whore).

Worldcrunch.com also points out the Catholic Church's ownership (50% equity) in another publishing company called Droemer Knaur, which has its own line-up of erotic materials such as "Sag Luder zu mir!" (Call Me Slut!),"Nimm mich hier und nimm mich jetzt!" (Take Me Here, Take Me Now!).
