Many modern day evangelicals pit the historicity of the information contained in scripture against the symbolic/typological overtones and meanings in the text. But perhaps God, the Master Playwright, meant for it all to work together. Consider John chapter 21. We read that the disciples caught 153 large fish. 153 is the triangular of 17. 17 is 7 + 10, and has to do with the nations of the world, as there were 70 (70 x 10) in Genesis 10. In Acts 2 we find there are 17 nations present. So, yes 153 is a new covenant form of the 70 nations of the world. But, still, there really were 153 large fish caught.
