Birth And Sanctity

Ideoque, et quod nascetur ex te sanctum, vocabitur Filius Dei. Ad distinctionem nostrae santitatis, Jesus singulariter sanctus nasciturus asseritur. Nos quippe et si sancti efficimur, non tamen nascimur, quia ipsa naturae corruptibilis conditione constringimur. Ut merito cum Propheta gementes singuli dicamus: Ecce enim in inquitatibus conceptus sum, et in delictis peperit me mater mea. Ille autem solus veraciter sanctus est qui, ut ipsam conditionem naturae corruptibilis vinceret, ex commistione carnalis copulae conceptus non est. Sanctum, inquit, vocabitur Filius Dei. Quid hic dicis, Nestorinae, qui beatam Mariam Dei negans esse genitricem, apertam niteris impugnare veritatem? Ecce Deum dixit superventurum, Dei Filium nasciturum. Quomodo ergo aut Dei Filius non est, aut quae Deum edidit, quomodo Θεοτόκος, id est, Dei genitrix non esse potest? Sanctus Beda,In Lucae Evangelium Expositio, Liber Primus Source: Migne PL 92.319a-b

Therefore since what will be born of you is holy, He shall be called the Son of God. 1 In distinction to our sanctity, it is asserted that Jesus alone shall be born holy. For we, even if we are made holy, are not born so, because we are constrained by the condition of our corruptible nature. So rightly, groaning with the Prophet, each one of us may say, 'Behold, I was conceived in iniquity and in sin my mother birthed me.' 2 He alone is truly holy who, that He conquer that condition of corruptible nature, was not conceived by the mixing of carnal copulation. 'Holy,' he says, 'He shall be called the Son of God.' And what do you say, Nestorian, who denying the blessed Mary to be mother, endeavour to impugn the manifest truth? Behold, he said, God shall come, the Son of God shall be born. How, then, is He not the Son of God, or how can it be that she from whom God came forth, is not Theotokos, that is, the Mother of God?
