How did Thiering connect early Christianity to the Qumran sectarians?

Les explains that Dr. Thiering, laboring at the University of Sydney in Australia and committed to studying the Dead Sea Scrolls, came up with the idea that the Gospels especially were written on two levels: one for ordinary readers and another reality only she could pull out of the Dead Sea Scrolls. Les notes this was a book review, not the view of Biblical Archaeology Review, and they were not in agreement with it. According to the review, Thiering was helped by the Dead Sea Scrolls: the similarities all scholars see between early Christianity and the Qumran sectarians suggested to her that the Qumran sect represented the form of Judaism out of which Christianity came. She then concluded that the famous Teacher of Righteousness of the Qumran text was John the Baptist, and that his opponent, the Wicked Priest conflated with the Man of Lie, was Jesus. She also said the virgin birth story was written at the level of a miracle for those for whom the idea of a virginal conception had symbolic power.
