That sounds all nice and good, Pterist, but history shows that the spread of private interpretation has been disastrous for the faith. What made the Protestant revolution possible wasn't the work of God; it was the dismantling of Catholic power (separation of Church and State) in Germany. Even Luther regretted what became of the movement. The debauched and bloody Reformation in places like Muenster and Tabor was proof positive of the consequences of all the private interpreting going on. Germany was one big Waco, Texas full of Branch Davidians rolling around in pig dung, running around naked, and committing all kinds of fornications.
What I am saying isn't to minimize the intimacy between an individual believer and God. It has more to do with doctrine. You, as a Preterist, should appreciate the unity of the Universal Church during the Millennial Reign of Christ. After the 1,000 years was up, Satan went to work through the Judaizing and Reformation of the Church. Don't you see the ending of the 1,000 years and the proliferation of Sola Scriptura as evidence that Satan had been unleashed on the Church?
