Methodius — Concerning Free Will (On God and Matter 11)

How then do you say he left the qualities of the worthless as they were? Was he able to remove them too, but unwilling — or did he lack the power?

If you say he was able but unwilling, you must call him their cause: able to make them not be bad, he allowed them to remain as they were — especially when he began to craft the matter. If he had no care for matter at all, he would not be cause of what he let remain; but since he crafts one part and leaves another as it is, though able to turn that too toward the better, he seems to me to incur blame for leaving a wicked part of matter to the ruin of what he crafted.
