27. What room is any longer left for doubt? The Lord Himself proclaiming that the chief commandment of the law is to confess and love the one Lord, proves Himself to be Lord not by words of His own, but by the Prophet’s testimony, always signifying, however, that He is Lord, because He is the Son of God. By virtue of His birth He abides in the mystery of the one God, for the birth transmitting with it, as it did, the nature of God is not the issuing forth of another God with a different nature; and, because the generation is real, neither is the Father degraded from being Lord, nor is the Son born less than Lord. The Father retains His authority, the Son obtains His nature. God the Father is one Lord, but the Only-begotten God the Lord is not separated from the One, since He derives His nature as Lord from the one Lord. Thus by the law Christ teaches that there is one Lord; by the witness of the prophets He proves Himself Lord also.

27. Epilogus.---Quis ergo est jam nunc relictus ambigendi locus? Dominus ipse praecipuum mandatum legis in unius Domini confessione ac dilectione docens esse, non suo ad 279 Scribam, sed Prophetae testimonio usus est, esse se Dominum: Dominum se tamen semper per id, quod Dei filius est, esse significans. Per id enim in sacramento Dei unius per nativitatem manet, quia Dei in se naturam Dei nativitas tenens, in Deum alterum non excedat diversitate naturae; et veritas generationis nec Patri 0302C adimat ne non Dominus sit, nec Filio non perficiat ne non sit et Dominus. Atque ita neque auctoritatem Pater amittit, nec naturam Filius non tenet: per quod nec Deus pater non Dominus unus est, neque unigenitus Deus Dominus separatur ab uno; cum ex uno Domino unus ipse subsistat in Dominum: Dominum unum ita ex lege docens, ut se quoque Dominum Propheta teste confirmet (David Psal. CIX).
