Timothy Williamson has recently argued for necessitism, according to which anything that exists in one possible world exists in every possible world; that is, that every possible being is a necessary being. However, that doesn't mean that every possible being has the property of being concrete at every possible world (and so there are plenty of worlds at which we are mere abstract objects).
If true, necessitism would to have interesting implications for certain views in philosophy of religion. For example, it would mean that if an Anselmian being exists, then it is just one among infinitely many other necessary beings. Of course, one could reply that an Anselmian being still retains its unique and superlative status in virtue of being the only being who exists concretely at every possible world. Perhaps that's a difference that matters. Still, it seems to me that it would chip away at at least some of an Anselmian being's greatness.
