No one will judge more justly than He who was unjustly judged. Take some other instances. For piety may still exist, though he who was pious became impious. He has lost his piety, but has taken nothing from piety itself. And so of chaste and chastity.
Chastity is clearly something more than chaste.
If we say so, we shall begin to say that the Son is greater than the Father. The Son is the truth, the Father true. I inquire which is the greater, but find equality. For the true Father is true not because He contained a part of that truth, but because He begat it entire. I see I must speak more plainly.
