According to The Orange County Register:
Harvest Christian Fellowship will be joining the Southern Baptist Convention, the nation’s largest Protestant body with about 15 million members. The Rev. Greg Laurie, pastor and founder of the 15,000-member Harvest and its Harvest Crusades, announced the move in June.
Some theologians see this as Laurie’s official shift toward mainstream evangelicalism and worry that Riverside-based Harvest could be overshadowed by the denomination. Laurie has been seen as one of the biggest crusaders of Calvary Chapel, an association of evangelical Christian churches to which Harvest belongs. Calvary was born as a movement away from religious denominations.
