Thanks Prudence, you raise great questions, of course. First, on the physical resurrection, the physiology matters a great deal. It is not only very significant for eschatology, but also in understanding the nature of human consciousness in the universe. As John Polkinghorne points out, it makes bodily existence very important showing that there is ultimately a unity of body and soul. It's one reason why I latched onto the idea of dual aspect monism, in which there is that underlying unity of mind and matter found in a substrate that is neither and both mind and matter. The most basic biblical teaching of the eschaton is of bodily resurrection within the restoration that involves the unification of heaven and earth.

As for exclusivity, Jesus said I am the way, the truth and the life, no one comes to the Father but by me. What about the Old Testament saints and patriarchs. Abraham did not know Jesus, so how could he be saved? I have long subscribed to CS Lewis' thoughts on this (The Great Divorce is about my favorite book). He said ultimately there are two kinds of people: those who say to God Thy will be done, and those to whom God says, finally, Thy will be done. In other words, I do not know their hearts nor could I nor would I attempt to judge. The saying of Jesus refers not to speaking his name, impossible for those who came before and who culturally or genetically or on any other basis never had a chance to do so It refers to the act of his life, death and resurrection as the means by which the promise of restoration of all things is secured.

Thanks for allowing me the opportunity to explain.
