Foolish heretic, who treat with scorn so fine an argument of God’s greatness and man’s instruction! God put the question with an appearance of uncertainty, in order that even here He might prove man to be the subject of a free will in the alternative of either a denial or a confession, and give to him the opportunity of freely acknowledging his transgression, and, so far, of lightening it.
Tertullian
The Five Books Against Marcion, Book II
Chapter XXV
