Since nobody has answered your question to my satisfaction, i will try. I have in the past attempted to show how God creates out of nothing without contradiction. Continuously people have failed to comprehend. Perhaps this is knowledge that God allows to only a few people. I should point out that what is essentially meant by ex-nihilo is that God does not create out of actual physical materials that already exist. Also, peoples failure to understand creation ex-nihilo is rooted in today’s rejection of Aquinas’s metaphysics, or rather peoples failure to fully understand it.
Out of nothing comes nothing. This is an absolute fact which is impossible to overcome without throwing reason and the very idea of impossibility entirely out the window. Thus the theist cannot hide from the problem that ex nihilo raises; that is if they value a rational faith. In fact ex-nihilo does not involve creating a new “existence” out of nothing, as this would prove to be impossible, but rather it involves the actuality of potential essences, and this is achieved by coupling the nature that is “existence” (pure eternal actuality) with the abstract idea of some possible thing or essence in Gods knowledge. By God having perfect knowledge of himself, God is able to know all possible things (which, before becoming actual, exist as abstract objects), and through his eternal love God wills and shares his nature (existence) with his knowledge of those abstract things.
Of course, you would have to understand that existence is a “nature” (eternally actual) in which and through which possible or potential things have their actuality and are sustained.
Of course this would seem to the uninitiated like pantheism or panentheism. I cannot blame them for thinking so. But here we are not saying that all things are God, but rather we are saying that there is and only has ever been “one” existence through which all potential **essences **have their being. But there are many distinct essences in reality that are not intrinsic to Gods nature. If all things were God, they would have always existed in Gods intrinsic nature, never having a beginning and never changing, since they are by nature “existence”. However, Gods intrinsic nature cannot be identified as a potential or finite being and thus no potential essence is intrinsically God but is instead its own essence and not Gods essence. For example, while God is the being through which the essence of a mouse has actuality, Gods essential and intrinsic nature is not a mouse. The mouse, while actual, is a distinct finite contingent essence, rather than a necessary expression of reality. The two are infinitely distinct, essentially speaking; but they share the same act or esse.
God does not create new existences out of nothing. God creates essences ex-nihilo.
Does anybody understand this?
