Mr. Cho was born in 1936 in Ulju, in southeastern South Korea, when the Korean Peninsula was still a colony of Japan. He was a student of a vocational high school in Busan, a southern port city crowded with refugees of the Korean War, when he became ill with tuberculosis. He has said that his miraculous recovery came with a religious awakening. He was also influenced by Kenneth Tice, a Pentecostal Assemblies of God missionary from the United States.
Mr. Cho and Choi Ja-shil, a Pentecostal pastor who would later become his mother-in-law, started a church in a Seoul slum under a tent that had been discarded by the U.S. military in 1958. There were only five members on the church’s first day, three of whom were Ms. Choi’s relatives. Another was an old woman who came into the tent to avoid the rain.
But soon, Mr. Cho and Ms. Choi drew worshipers as word spread that they could heal the sick at a time when millions lived without access to medical services. Mr. Cho also preached “hope” and “positive thinking,” convincing people struggling under postwar penury that religious faith would bring three rewards: wealth, health and spiritual comfort.
In 1973, to accommodate his growing congregation, Mr. Cho opened the church building in Yoido, which was then an undeveloped island. (The island is now home to the country’s National Assembly and top financial institutions.) By 1993 the church had 700,000 worshipers and was recognized by Guinness World Records as the largest congregation. The church continued growing as Mr. Cho divided Seoul into several proselytizing sectors, assigning deputies to each one.
Mr. Hwang said that when he was studying in Canada in the 1990s, he was surprised to learn that more Canadians had heard of Mr. Cho than the South Korean president.
Mr. Cho also started charity programs for the needy, including raising money for children with heart diseases. His $17 million plan to build a hospital for patients with heart ailments in Pyongyang, the North Korean capital, is on hold as relations between the two Koreas remain tense over the North’s nuclear weapons program.
