16 This being the nature of Origen's book, is it anything short of madness to change a few blasphemous passages regarding the Son and the Holy Spirit and then to publish the rest unchanged with an unprincipled eulogy when the parts unaltered as well as the parts altered flow from the same fountain head of gross impiety? This is not the time to confute all the statements made in detail; and indeed those who have written against Arius, Eunomius, Manichæus, and various other heretics must be supposed to have answered these blasphemies as well. If anyone, therefore, wishes to read the work let him walk with his feet shod towards the land of promise; let him guard against the jaws of the serpent and the crooked jaws of the scorpion; let him read this treatise first and before he enters upon the path let him know the dangers which he will have to avoid.
