About 300 Protestant church members will gather in downtown Seoul to hold a group prayer against the concert in the capital, Kang Ju-Hyun, a prayer organiser told AFP.
“We will pray to God that the concert will not be realised so that homosexuality and pornography will not spread around the country,” he said.
Kang, who leads a group called Alliance for Sound Culture In Sexuality, said other major church groups would join his campaign by holding protests around the Seoul headquarters of Hyundai Card, the concert organiser.
The Korean Association of Church Communication vowed last month to take “concerted action to stop young people from being infected with homosexuality and pornography.”
South Koreans aged under 18 have been banned from the much-anticipated concert after it was rated unsuitable for younger audiences.
The show had an initial age rating of 12 and older but the Korea Media Rating Board — a state watchdog — adjusted it upwards.
South Korea has East Asia’s largest Christian community after the Philippines, with about 8.6 million Protestants and 5.1 million Catholics. About 10 million South Koreans are Buddhists
