Matthew 5:48

But as God is eternal and rational, so, I think, He is perfect in all things. "Be ye perfect, even as your Father which is in heaven is perfect." Prove, then, that the goodness of your god also is a perfect one. That it is indeed imperfect has been already sufficiently shown, since it is found to be neither natural nor rational. The same conclusion, however, shall now be made clear by another method; it is not simply imperfect, but actually feeble, weak, and exhausted, failing to embrace the full number of its material objects, and not manifesting itself in them all.[Tertullian Adv Marc 1.24.1 KROYMANN Aem., CCL 1 (1954), (p.466, l.30) BP1]
