Lee Jae Rock sounds like a great spiritual healing evangelist and does preach biblica1 sermons at his large public crusades, but underneath the surface is in reality a heretical teacher. Unfortunately, information about the heresy and highly questionable character of Lee Jae-Rock is rare in English (though a number of books and websites in Korean do expose him.)
He was excommunicated as a cult leader from his own denomination (Church of Holiness) in May 1990 and from the Korean Christian Association (Han Ki Chong) on 30th of April 1999 because of his unbiblical teachings.
Lee Jae-Rock (also known as Jaerock Lee) claims to have received revelation just like the Apostle John. He claims his body has sinless blood (due to a blood transfusion in 1992). He meets with the prophets, apostles and patriarchs. His spirit is at the left side of God's throne. He will be the judge on the last day and all the angels submit to him. And he has made many more such claims.
In Korea a documentary video was aired exposing Lee Jae-Rock's bizarre claims and gambling activities. A number of his followers stormed the TV facility to prevent the broadcast. At least 600 South Korean riot police were called out to end the occupation. The Manmin church had earlier reportedly obtained a court order preventing MBC from screening a story about Lee Jae-Rock's sex life.
