What did the Early Church believe about the Kingdom? What happened in later centuries? What does the Encyclopedia Britannica record in terms of the kingdom beliefs of the church throughout the two-thousand year history since Jesus Christ? What do present-day Christians believe about the Kingdom? What are the differences between the Modernists, Fundamentalists and Spiritualists? Do any of them hold upto the Scriptural truths?

Spiritualists theorize that the Kingdom is just in the spiritual realm. They usually quote Luke 17:21 to claim the Kingdom is "within" people. Did Jesus really tell the Pharisees that his Kingdom was within their hearts? What did he actually tell them? How can his statement be harmonized with the rest of the Bible?
