37. Yet to prevent the declaration of one God seeming to affirm that God is a solitary monad without offspring of His own, it immediately condemns the rash suggestion that because God is one, therefore God the Father is one and solitary, having in Himself the name of Father and of Son: since in the Father who begets and the Son who comes to birth one God must be declared to exist on account of the substance of their nature being similar in each. The faith of the saints knows nothing of the Son being incapable of birth: because the nature of the Son only draws its existence from birth. But the nature of the birth is in Him so perfect that He who was born of the substance of God is born also of His purpose and will. For from His will and purpose, not from the process of a corporeal nature, springs the absolute perfection of the essence of God born from the essence of God. It follows that we should now consider that creed which was compiled not long ago when Photinus was deposed from the episcopate.
A copy of the creed composed at Sirmium by the Easterns to oppose Photinus.
37. Non tamen fides solitarium Deum, Filium recte docet innascibilem. Qui ex voluntate nascatur.---Tamen 0509A ne rursum unius Dei praedicatio unicam ac sine progenie sua solitarii Dei velit affirmare substantiam; statim hanc condemnat temeritatem, quae quia Deus unus est, unum ac solitarium Deum patrem, habentem in se nomen et patris et filii confiteretur: cum in generante Patre et nascente Filio Deus unus esset ob indifferentis ab invicem naturae substantiam praedicandus. Innascibilem quoque Filium sanctorum fides nescit: quia natura Filii nisi ex nativitate non exstat. Nativitatis autem in eo adeo perfecta natura est, ut qui ex substantia Dei natus est, etiam ex consilio ejus ac voluntate nascatur. Ex voluntate enim atque consilio, non ex corporalis passione naturae, essentiae Dei de essentia Dei genitae absoluta perfectio est. Consequens autem est, ut eam nunc fidem 0509B retractemus, quae non olim cum Photinus episcopatu dejectus est, conscripta est.
