16. With the Son’s origin as thus stated is connected the perfect birth of the undivided nature. For what in each is life, that in each is signified by essence. And in the life which is begotten of life, i.e. in the essence which is born of essence, seeing that it is not born unlike (and that because life is of life), He keeps in Himself a nature wholly similar to His original, because there is no diversity in the likeness of the essence that is born and that begets, that is, of the life which is possessed and which has been given. For though God begat Him of Himself, in likeness to His own nature, He in whom is the unbegotten likeness did not relinquish the property of His natural substance. For He only has what He gave; and as possessing life He gave life to be possessed. And thus what is born of essence, as life of life, is essentially like itself, and the essence of Him who is begotten and of Him who begets admits no diversity or unlikeness.
V. “If any one hearing the words formed or created it and begat me spoken by the same lips11 Prov. viii. 22., refuses to understand this begat me of likeness of essence, but says that begat me and formed me are the same: as if to deny that the perfect Son of God was here signified as Son under two different expressions, as Wisdom has given us to piously understand, and asserts that formed me and begat me only imply formation and not sonship: let him be anathema.”
16. Connectitur, tali confessione originis suae, indiscretae naturae perfecta nativitas. Quod enim in utroque vita est, id in utroque significatur essentia. Et in vita quae generatur ex vita, id est, essentia quae de essentia nascitur, dum non dissimilis nascitur, scilicet quia vita ex vita est, tenet in se originis suae indissimilem naturam; quia natae et gignentis essentiae, id est, vitae quae habetur et data est (nempe a Patre et data est Filio), similitudo non discrepet. 0492C Quod enim ex se Deus, cum ex naturae suae similitudine, 0493A genuit; non deseruit, in quo ingenita similitudo, naturalis proprietatem substantiae. Non enim aliud habet, quam dedit: et sicut vitam habens, ita habendam dedit vitam. Ac sic quod de essentia, tamquam vita ex vita, simile sui secundum essentiam nascitur, nullam diversitatem ac dissimilitudinem admittit nascentis et gignentis essentia.
V. «Si quis condidit vel creavit me (Prov. VIII, 22), et genuit me (Ibid. 25) ab eodem audiens, hoc genuit me non tam ex similitudine essentiae intelligat, sed idem esse dicat genuit me, et condidit me: quasi non dicens Filium de Deo perfectum ex duobus nominibus significatum filium (sed per duo nomina, hoc est, condidit me, et genuit, conditionem tantummodo dicens, et nequaquam 0493B filium); sicut 470 tradidit Sapientia ex duobus pium intellectum: anathema sit.»
