60. To declare the Son to be incapable of birth is the height of impiety. God would no longer be One: for the nature of the one Unborn God demands that we should confess that God is one. Since therefore God is one, there cannot be two incapable of birth: because God is one (although both the Father is God and the Son of God is God) for the very reason that incapability of birth is the only quality that can belong to one Person only. The Son is God for the very reason that He derives His birth from that essence which cannot be born. Therefore our holy faith rejects the idea that the Son is incapable of birth in order to predicate one God incapable of birth and consequently one God, and in order to embrace the Only-begotten nature, begotten from the unborn essence, in the one name of the Unborn God. For the Head of all things is the Son: but the Head of the Son is God. And to one God through this stepping-stone and by this confession all things are referred, since the whole world takes its beginning from Him to whom God Himself is the beginning.
XXVII. “Once more we strengthen the understanding of Christianity by saying, If any man denies that Christ, who is God and the Son of God, existed before time began and aided the Father in the perfecting of all things; but says that only from the time that He was born of Mary did He gain the name of Christ and Son and a beginning of His deity: let him be anathema.”
60. Filium innascibilem unitas Dei non patitur.---Filium innascibilem confiteri, impiissimum est. Jam enim non erit Deus unus: quia Deum unum praedicari natura unius innascibilis Dei exigit. Cum ergo unus Deus sit, duo innascibiles esse non possunt: cum idcirco Deus unus sit (cum et pater Deus sit, et filius Dei Deus sit), quia innascibilitas sola penes unum sit. Filius autem idcirco Deus, quia ex innascibili essentia natus exsistat. Respuit ergo innascibilem Filium praedicari fides sancta; ut per unum innascibilem Deum, unum Deum praedicet: ut naturam unigenitam, ex innascibili genitam essentia, in uno innascibilis Dei nomine complectatur. Caput enim omnium Filius est, sed caput Filii Deus est. 0521C Et ad unum Deum omnia hoc gradu atque hac confessione referuntur: cum ab eo sumant universa principium, cui ipse principium sit (scil. Deus pater).
XXVII. «Et iterum confirmantes Christianismi inintellectum, dicimus, Quoniam si quis Christum Deum, filium Dei ante saecula 497 subsistentem, et ministrantem Patri ad omnium perfectionem non dicat; sed ex quo de Maria natus est, ex eo et Christum et filium nominatum esse, et initium accepisse ut sit Deus dicat: anathema sit.»
