Empther:
“12. Angels do not know the future; :bigyikes: they do not know the secret thoughts of other rational creatures; they do not know the mysteries of grace, unless such things be revealed freely, either by God or by other rational creatures.” -
ibid.
“Our twelfth theorem is clear by its very enunciation. Angelic knowledge is not only of abstract things but of concrete things. The future free acts of created rational beings are not knowable to a created intellect. God alone contemplates them with infallible security of vision in the light of his eternity. For the same reasons which make it impossible for a spirit to act directly on the will of any rational creature we may say that the secret thoughts of the heart of man or the mind of a spirit are hidden, unless freely revealed by the one who thinks the thought. In every thought there is an act of will, because I think when I will and I think what I will, but the hiddenness of the will covers my very thoughts. The mysteries of grace are the decision, not of a created will, but of the will of God.
A fortiori it will ever be far beyond a created spirit’s ken to find out what God is thinking, unless God be pleased to reveal his thoughts.” -
