3 What work, then, will they point to as having been accomplished through themselves by the Saviour, or by their Mother, either greater, or more glorious, or more adorned with wisdom, than those which have been produced by Him who was the disposer of all around us? What heavens have they established? What earth have they founded? What stars have they called into existence? Or what lights of heaven have they caused to shine? Within what circles, moreover, have they confined them?
Or, what rains, or frosts, or snows, each suited to the season, and to every special climate, have they brought upon the earth? And again, in opposition to these, what heat or dryness have they set over against them? Or, what rivers have they made to flow? What fountains have they brought forth? With what flowers and trees have they adorned this sublunary world? Or, what multitude of animals have they formed, some rational, and others irrational, but all adorned with beauty? And who can enumerate one by one all the remaining objects which have been constituted by the power of God, and are governed by His wisdom?
Or who can search out the greatness of that God who made them? And what can be told of those existences which are above heaven, and which do not pass away, such as Angels, Archangels, Thrones, Dominions, and Powers innumerable? Against what one of these works, then, do they set themselves in opposition? What have they similar to show, as having been made through themselves, or by themselves, since even they too are the Workmanship and creatures of this [Creator]? For whether the Saviour or their Mother (to use their own expressions, proving them false by means of the very terms they themselves employ) used this Being, as they maintain, to make an image of those things which are within the Pleroma, and of all those beings which she saw waiting upon the Saviour, she used him (the Demiurge) as being [in a sense] superior to herself, and better fitted to accomplish her purpose through his instrumentality; for she would by no means form the images of such important beings through means of an inferior, but by a superior, agent.
