[Some] confess that the Father of all contains all things, and that there is nothing whatever outside of the Pleroma (for it is an absolute necessity that, [if there be anything outside of it,] it should be bounded and circumscribed by something greater than itself), and that they speak of what is without and what within in reference to knowledge and ignorance, and not with respect to local distance; but that, in the Pleroma, or in those things which are contained by the Father, the whole creation which we know to have been formed, having been made by the Demiurge, or by the angels, is contained by the unspeakable greatness, as the centre is in a circle, or as a spot is in a garment . . . .
