Rupert Missionary Baptist Church is: Baptist: Too many of our modern day churches claim to be Baptist, but their doctrinal and social positions are far from what Baptists have stood for in the past. The Rupert Missionary Baptist Church is like the old Baptists such as BH Carroll, JR Graves, and Charles Spurgeon. Historical: We believe Jesus Christ established His church during His lifetime here on earth. He took men who were baptized by John the Baptist and established His church. He then commissioned that church to go and duplicate itself throughout the world.
