Suppose that there is an actus purus, a being that is entirely active, impassible (nothing happens to this being), and which has no proper parts (its only part is itself entirely), not even abstract parts. It would be hard to deny all distinctions to it, e.g. if we said that the intrinsic/extrinsic distinction doesn't apply to it, then all its otherwise internal reality is also its external reality, or even none of it is interior or exterior at all to its identity (which is hard for me to think through, though). But perhaps the general/particular distinction is one that doesn't hold for it, or at least not in the normal way (or: its degree of generality is somehow equal to its degree of particularity and it is "equigeneous" or "equimorphic" or something).
Now, could such an entity issue multiple commands? Often we think that such beings might create multiple objects, but is a command more like an object created, or more like the act of creating? (The poesy of various scriptures betimes likens the act of creation to the issuance of a command, e.g., "Let there be light.") If commands are creatable, then it would seem as if such a being could issue multiple commands; however, suppose this being's will is not created, and is an example of the extremely unified being's extreme unity. Then its will can be expressed by only one command, or not?
Does extreme monotheistic divine-command theory require that its ultimate agent ever issue only one specific command? If the simplicity at stake concerns also the general/particular distinction, would it be better to say that this deity can issue a single equimorphic command, which being general in its (the command's) own way (as well as uniquely specific) then has other commands subsumed under it? Or is it a proper test of a proposed divine-command theory that it should have but one real precept to its (the theory's) name, with other moral commands not falling out of the system as inferences from the one precept but as commands that are consistent expansions on the precept's side?
