False premise.
God cannot do anything.
Even Scripture tells us that there are things God cannot do.
We can point them out if you need.
There is nothing REAL that God cannot do.
Of course, God cannot make a square circle, or a rock so heavy that he cannot lift it, because those are not real things.
God cannot do things that are contrary to his nature. E.g., God cannot lie, or have malice.
Catholics and agnostics like to say ‘God can do anything’ in order to leave a gapping hole in reason into which they pour their magic thinking. We see it in abundance on this thread, with the elevation of Mary to demi-goddess by claiming she is the mother of a third of the Trinity of God. Such false reasoning gives the magic thinkers a big hole into which they can pour all manner of heresy with a seared conscience. Perhaps the inability to see the faulty reasoning is why they remain perishing in catholiciism? Perhaps they are so far lost that they cannot pull back from the plunge the demonic has pushed them into?
Good grief Charlie Brown, now the protestants have a list of things that God can't do.....like create a rock that even He can't lift????
