"Thomas Aquinas."
Does this god know he was defined by this man, Aquinas?
If you have access to a dictionary look up "omniscient". If you are serious read the Summa Theologica in which St. Thomas Aquinas stated; "That is perfect, which lacks nothing of the perfection proper to it.". If you are simply a knee-jerk anti-Catholic prefer a less Catholic source I would direct you to John Wesley, founder of Methodism, whose doctrines are largely founded on this definition.
