The Unification Church has declared 13 days of mourning for its controversial founder the Rev Sun Myung Moon.
The 92-year-old self-proclaimed messiah who built a global business empire died on Sunday at a church-owned hospital near his home in Gapyeong County, north east of Seoul, South Korea, two weeks after being admitted to hospital with pneumonia, church spokesman Ahn Ho-yeul said. His wife and children were at his side.
The church will start accepting mourners at a multi-purpose gym at its nearby religious centre on Thursday, Mr Ahn said.
The funeral will be held on September 15 and Moon will be buried at Cheonseung Mountain, near his home.
Moon founded his Bible-based religion in Seoul in 1954, a year after the Korean War ended, saying Jesus Christ personally called on him to complete his work.
The church gained fame - and notoriety - by marrying thousands of followers in mass ceremonies presided over by Moon himself. The couples often came from different countries and had never met, but were matched up by Moon in a bid to build a multi-cultural religious world.
The church has been accused of using devious recruitment tactics and duping followers out of money.
Parents of followers in the United States and elsewhere have expressed worries that their children were brainwashed into joining.
Moon's followers were often called "Moonies", a term many found pejorative.
