ABSTRACT
By the mid-1920s, mainline Protestant boundaries were no longer expansive or elastic enough to embrace Pentecostalism. Although Aimee Semple McPherson had blurred the boundaries in the early 1920s and had introduced the movement to the Protestant mainstream, a reaction quickly ensued, and McKendree Methodist Church was representative of that story as well. McKendree Methodist Church in many ways served as a microcosm for what was occurring in American Pentecostalism as a whole. Not only was Aimee able to win many mainline converts for the movement, she was also both directly and indirectly responsible for adding many Full Gospel Tabernacles and churches to the ranks of the Assemblies of God. The creation of new Protestant boundaries in the mid-1920s had a far greater impact on mainline Protestantism, however, than it ever did upon Pentecostalism. That movement did just fine sitting on the sideline. That movement did just fine sitting on the sideline.
