The Spirit of Jesus Church (イエス之御霊教会, Iesu no Mitama Kyōkai) was registered in 1941 in Japan by Murai Jun. The church was named in accordance with a heavenly vision he reportedly received in 1941. The core mission of the Spirit of Jesus Church is defined in the Gospel of Mark 16:15-18. There he instructed his disciples to preach the gospel and baptize the believers, and promised the power to perform miracles, cast out demons, speaking in tongues, and heal the sick. It is one of the fastest-growing Christian bodies in Japan, having increased its membership from 34,477 in 1970 to 433,108 at the end of the 1980s. Taken at face value, the Spirit of Jesus Church is one of the largest new religious movements in Japan.[1] They also reject the Trinitarian doctrine and claims to be the only true Christian church in the world.
