GraceLife London is what is known as a “church plant.” It is one of hundreds of affiliated churches and ministries scattered around the world. It belongs to a church-planting parachurch network headquartered at Grace Community Church in Sun Valley, California. John MacArthur, who took over the pastorate of Grace Community Church in 1969, is a lion in America’s Christian nationalist circles but little known outside of them. His Sun Valley church draws thousands of weekly attendants, and the Master’s Seminary in Los Angeles, which he has led since 1986, has trained some of the most politically influential and connected of America’s Christian nationalist preachers in the same hyperpatriarchal, homophobic, end-times religion on display at GraceLife London.
