Christ created the Christian church when he told his disciples to stay together and await the Holy Spirit. He created it when He told them to go forth and make disciples in his name. There is no such thing as cowboy, rugged individualist Christianity.
How did he teach us to pray ? Our Father, who art in heaven, hallowed be thy name...Give us this day our daily bread...and forgive us our trespasses...
I am not suggesting there is not the church that Christ established. I am saying that everyone who is a member of the body of Christ should simply be called Christians.
Nonbelievers are not disciples.
