Basically the criticism goes as follows, according to Christianity God has existed forever, as a sort of Mind, or Objective Ideal (the latter defined in the sense as something non-material, yet existing outside of human subjectivity). The problem with this viewpoint however is that if God has no Genesis, then the fact that such a God is capable of change is by its very nature contradictory. For how do the elements separate from that of the Eternal-Absolute-God being come about by which to contrast to the Absolute God being?
In other words, for God to create the material universe, God must invoke elements that are non-God. But God is supposed to be absolute-complete and unchanging. Yet God was all that existed at one point, ergo, how did God create non-God elements out of God?
Such would make it so existence was God- and non-God simultaneously, with God simultaneously encompassing all of existence.
Thus the notion of God is by definition contradictory if God is posited as eternally existing prior to all other existence.
