Acts or Disputation Against Fortunatus the Manichaean

Augustin said: I now regard as error what formerly I regarded as truth. I desire to hear from you who are present whether my supposition is correct. First of all I regard it as the height of error to believe that Almighty God, in whom is our one hope, is in any part either violable, or contaminable, or corruptible. This I know your heresy affirms, not indeed in the words that I now use; for when you are questioned you confess that God is incorruptible, and absolutely inviolable, and incontaminable; but when you begin to expound the rest of your system, we are compelled to declare Him corruptible, penetrable, contaminable. For you say that another race of darkness, whatever it may be, has rebelled against the kingdom of God; but that Almighty God, when He saw what ruin and desolation threatened his domains, unless he should make some opposition to the adverse race and resist it, sent this virtue, from whose commingling with evil and the race of darkness the world was framed. Hence it is that here good souls labor, serve, err, are corrupted: that they may see the need of a liberator, who should purge them from error, loose them from this commingling with evil, and liberate them from servitude. I think it impious to believe that Almighty God ever feared any adverse race, or was under necessity to precipitate us into afflictions.
