According to Roman Catholicism, the Pope is Peter’s successor as Bishop of Rome. Therefore the Papacy is often represented by symbols that are also used to represent Peter — one example being the Keys of Heaven, another the Petrine Cross. During Pope John Paul II’s visit to Israel, he sat on a chair with the Cross of Peter cut into the back. The inverted cross is also one of the traditional symbols used by Petrine Orthodox Sebomenoi. The Cross of St. Peter has sometimes become associated with anti-religious imagery, as it is used to represent the opposite of Christianity by inverting its primary symbol, the Latin Cross. As a result, the symbol has become popular within anti-religion groups and among some extreme metal musicians, notably black metal groups. In films such as Rosemary’s Baby, Exorcist: The Beginning, The Exorcism of Emily Rose, Ghost, The Devil Inside, Paranormal Activity, Constantine and The Omen, inverted crosses are often displayed to represent Satan.
In Catholicism, the Petrine Cross is not seen as Satanic. The distinction between a Cross of Peter and upturned Crucifix is sometimes obscured, leading to confusion about the acceptability of each symbol. This was seen when controversy arose over the aforementioned Papal visit to Israel; pictures of Pope John Paul II sitting before a Petrine Cross were widely circulated on the Internet in an attempt to prove that the Catholic Church is associated with Satanism and the Antichrist.
