The Vatican has opened its doors for its annual exorcism course amid increasing demand among some of the world’s Catholic communities.

As many as 250 priests from 50 countries have arrived in Rome to learn how to identify demonic possession, to hear personal accounts from other priests and to find out more about the rituals behind expelling demons.
Exorcism remains controversial, in part due to its depiction in popular culture and horror films. But there have also been some cases of abuse linked to exorcisms in a range of religious sects.
The week-long Vatican course is described as the only international series of lectures of its kind. Entitled Exorcism and the Prayer of Liberation, it first opened its doors in 2005 and the number of priests attending has more than doubled since then. The event costs €300 (£260, $370) and covers the theological, psychological and anthropological background to exorcisms.
Catholic priests in several countries have told the press there has been an increase in the numbers of people reporting signs of demonic possession.
Last year Pope Francis told priests that they “must not hesitate” to refer parishioners to exorcists if they suffer from “genuine spiritual disturbances”.
Half a million people reportedly seek exorcisms every year in Italy, while a report by Christian think-tank Theos in 2017 said that the practice was also on the rise in the UK, in part due to the spread of Pentecostal churches.
Some dioceses have developed their own courses to meet the growing demand, including in Sicily and the US city of Chicago.
