Chapter XVII.

That Christ is very God is proved from the fact that He is God’s own Son, also from His having been begotten and having come forth from God, and further, from the unity of will and operation subsisting in Father and Son. The witness of the apostles and of the centurion—which St. Ambrose sets over against the Arian teaching—is adduced, together with that of Isaiah and St. John.

108. Hence it is that Christ is not only God, but very God indeed—very God of very God, insomuch that He Himself is the Truth.198    S. John xiv. 6. If, then, we enquire His Name, it is “the Truth;” if we seek to know His natural rank and dignity, He is so truly the very Son of God, that He is indeed God’s own Son; as it is written, “Who spared not His own Son, but gave Him up for our sakes,”199    Rom. viii. 32. gave Him up, that is, so far as the flesh was concerned. That He is God’s own Son declares His Godhead; that He is very God shows that He is God’s own Son; His pitifulness is the earnest of His submission, His sacrifice, of our salvation.

109. Lest, however, men should wrest the Scripture, that “God gave Him up,” the Apostle himself has said in another place,200    Gal. i. 3, 4. “Peace from God the Father, and our Lord Jesus Christ, Who gave Himself for our sins;” and again:201    Eph. v. 2. “Even as Christ hath loved us, and given Himself for us.” If, then, He both was given up by the Father, and gave Himself up of His own accord, it is plain that the working and the will of Father and Son is one.

110. If, then, we enquire into His natural pre-eminence, we find it to consist in being begotten. To deny that the Son of God is begotten [of God] is to deny that He is God’s own Son, and to deny Christ to be God’s own Son is to class Him with the rest of mankind, as no more a Son than any of the rest. If, however, we enquire into the distinctive property of His generation, it is this, that He came forth from God. For whilst, in our experience, to come out implies something already existent, and that which is said to come out seems to proceed forth from hidden and inward places, we, though it be presented but in short passages, observe the peculiar attribute of the Divine Generation, that the Son doth not seem to have come forth out of any place, but as God from God, a Son from a Father, nor to have had a beginning in the course of time, having come forth from the Father by being born, as He Himself Who was born said: “I came forth from the mouth of the Most High.”202    Ecclus. xxiv. 3.

111. But if the Arians acknowledge not the Son’s nature, if they believe not the Scriptures, let them at least believe the mighty works. To whom doth the Father say, “Let us make man?”203    Gen. i. 26. save to Him Whom He knew to be His true Son? In Whom, save in one who was true, could He recognize His Image? The son by adoption is not the same as the true Son; nor would the Son say, “I and the Father are one,”204    S. John x. 30. if He, being Himself not true, were measuring Himself with One Who is true. The Father, therefore, says, “Let us make.” He Who spake is true; can He, then, Who made be not true? Shall the honour rendered to Him Who speaks be withheld from Him Who makes?

112. But how, unless the Father knew Him to be His true Son, should He commend to Him His will, for perfect co-operation, and His works, for perfect bringing in out in actuality? Seeing that the Son worketh the works which the Father doeth, and that the Son quickens whom He will,205    S. John v. 19, 21. as it is written, He is then equal in power and free in respect of His will. And thus is the Unity maintained, forasmuch as God’s power consists in that the Godhead is proper to each Person, and freedom lies not in any difference, but in unity of will.

113. The apostles, being storm-tossed in the sea, as soon as they saw the waters leaping up round their Lord’s feet, and beheld His fearless footsteps on the water, as He walked amid the raging waves of the sea, and the ship, which was beaten upon by the waves, had rest as soon as Christ entered it, and they saw the waves and the winds obeying Him,—then, though as yet they did not believe in their hearts they believed Him to be God’s true Son, saying, “Truly Thou art the Son of God.”206    S. Matt. xiv. 33.

114. To the same effect the confession of the centurion, and others who were with him, when the foundations of the world were shaken at the Lord’s Passion,—and this, heretic, thou deniest! The centurion said, “Truly this was the Son of God.”207    S. Matt. xxvii. 54. “Was” said the centurion—“Was not” says the Arian. The centurion, then, with bloodstained hands, but devout mind, declares both the truth and the eternity of Christ’s generation; and thou, O heretic, deniest its truth, and makest it matter of time! Would that thou hadst imbued thy hands rather than thy soul! But thou, unclean even of hand, and murderous of intent, seekest Christ’s death, so far as in thee lies, seeing that thou thinkest of Him as mean and weak; nay, and this is a worse sin, thou, albeit the Godhead can feel no wound, still wouldst do thy diligence to slay in Christ, not His Body, but His Glory.

115. We cannot then doubt that He is very God, Whose true Godhead even executioners believed in and devils confessed. Their testimony we require not now, but it is withal greater than your blasphemies. We have called them in to witness, to put you to the blush, whilst we have also cited the oracles of God, to the end that you should believe.

116. The Lord proclaimeth by the mouth of Isaiah: “In the mouth of them that serve Me shall a new name be called upon, which shall be blessed over all the earth, and they shall bless the true God, and they who swear upon earth shall swear by the true God.”208    Is. lxv. 16. These words, I say, Isaiah spake when he saw God’s Glory, and thus in the Gospel it is plainly said that he saw the Glory of Christ and spoke of Him.209    S. John xii. 41.

117. But hear again what John the Evangelist hath written in his Epistle, saying: “We know that the Son of God hath appeared, and hath given us discernment, to know the Father, and to be in His true Son Jesus Christ, our Lord. He is very God, and Life Eternal.”210    1 John v. 20. John calls Him true Son of God and very God. If, then, He be very God, He is surely uncreate, without spot of lying or deceit, having in Himself no confusion, nor unlikeness to His Father.

CAPUT XVII.

Christum Deum verum esse ex eo probat, quod sit proprius Dei Filius; praemissaque difficultatis suborientis solutione, eamdem rem inde confirmat, quod sit genitus, quodque ex Deo exierit. His subdit Patris ac Filii unitatem operationis ac voluntatis. Tum apostolis et Centurione quem cum Arianis contendit, in testimonium adductis Esaiam jungit ac Joannem.

108. Unde non solum Deus, sed etiam verus Deus, verus e vero, et adeo verus, ut ipse sit veritas. 0553C Itaque si nomen quaerimus, veritas est: si majestatem quaerimus naturalem, eo usque Filius Dei verus est, ut et proprius. Scriptum est enim: Qui proprio Filio non pepercit, sed pro nobis tradidit eum (Rom. VIII, 32): tradidit utique secundum carnem. Proprietas divinitatis est, veritas proprietatis, misericordia pietatis, oblatio securitatis.

109. Sed ne calumniarentur, quia scriptum est: Tradidit eum Pater; ipse Apostolus alibi dixit: Pax a Deo Patre, et Domino nostro Jesu Christo, qui se dedit pro peccatis nostris (Galat. I, 3, 4); et alibi: Sicut Christus dilexit nos, et tradidit semetipsum pro nobis (Ephes. V, 2). Si ergo et traditus est a Patre, et ipse se tradidit, apparet unam esse operationem, unam esse Patris et Filii voluntatem.

0553D 110. Si naturalem ergo majestatem quaerimus, genitus est. Qui genitum inficiatur, proprium negat: qui proprium abnuit, communem caeteris arbitratur. Sin vero generationis ipsius proprietatem requirimus, ex Deo exivit. Nam 466 cum in usu nostro id sit 0554A exire quod jam sit, et ex interioribus secretis prodire videatur, quod exire perhibetur: angustis licet sermonibus proprietatem divinae generationis advertimus; ut non ex loco aliquo videatur exisse, sed ut Deus ex Deo, Filius ex Patre; nec videatur coepisse ex tempore, qui ex Patre nascendo prodit, ut dixit ipse qui natus est: Ex ore Altissimi prodii (Eccles. XXIV, 5).

111. Sed si naturam non agnoscunt, si non credunt Scripturis, vel operibus credant. Cui dicit Pater: Faciamus hominem (Gen. I, 26), nisi ei quem verum Filium sciret? In quo nisi in vero suam imaginem recognosceret? Non est unum adoptivus et verus; nec Filius diceret: Unum sumus (Joan. XVI, 22); si se cum vero, qui verus non esset ipse, 0554B conferret. Faciamus ergo dicit Pater. Qui dixit, verus est: potestne ergo verus non esse ille, qui fecit; et quod dicenti defertur, facienti negatur?

112. Quomodo autem nisi verum Filium sciret, committeret ei voluntatis suae unitatem, et operis veritatem? Cum enim eadem faciat Filius opera, quae Pater facit, et quos vult vivificet Filius, sicut scriptum est (Joan. V, 19, 21); nec differens potestate, et liber est voluntate: ita unitas servatur; quia et virtus Dei in divinitatis proprietate est; et libertas non in aliqua differentia, sed in unitate est voluntatis.

113. Turbati in freto apostoli, licet adhuc non credentes corde, ubi primum sub pedibus Domini ludere aquas, et inquieto maris aestu deambulantis 0554C Domini super aquas intrepida videre vestigia; subitoque navi quae fluctibus turbaretur, ubi eam tamen Christus ascendit; placidata aequora, et elementa conspexere famulantia, verum Dei Filium crediderunt, dicentes: Vere Dei Filius es (Matth. XIV, 25 et seq.).

114. Hoc idem Centurio cum aliis qui secum erant, tremefactis mundi cardinibus in passione Domini confitetur: et tu, haeretice, negas! Centurio dicit: Vere Filius Dei erat iste (Matth. XXVII, 54). Erat, inquit Centurio, et Arianus dicit, non erat. Ille ergo generationis et veritatem et aeternitatem asserit manu cruentus, sed mente devotus: tu, haeretice, veritatem generationis negas, tempus ascribis. Utinam manus potius quam animam cruentasses! Sed 0554D nec manu innocens, et mente feralis, quantum in te est, mortem infers, qui infirmum opinaris; immo, quod gravius est, etsi divinitas vulnus sentire non possit, quod in te tamen est, majestatem suam in Christo, non corpus interficere conaris.

0555A 115. Verum igitur Deum dubitare non possumus, quem verum Dei Filium et carnifices crediderunt, et daemones fatebantur: quorum nunc non testimonia requiruntur, sed tuis tamen sacrilegiis praeferuntur. Illos nominavimus, ut erubesceres divina quoque responsa adhibuimus, ut crederes.

467 116. Clamat Dominus per Esaiam: Servientibus mihi vocabitur nomen novum, quod benedicetur super terram, et benedicent Deum verum: et qui jurant super terram, jurabunt per Deum verum (Esai. LXV, 16). Haec, inquam, dixit Esaias, quando vidit majestatem ejus. Hoc in Evangelio designatur, quod majestatem viderit Christi, et locutus sit de eo.

117. Accipe tamen quid etiam scripserit Evangelista Joannes in epistola sua dicens: Scimus quia Filius 0555B Dei apparuit, et dedit nobis sensum, ut cognoscamus Patrem, et simus in vero Filio ejus Jesu Christo Domino nostro. Hic est verus Deus, et vita aeterna (I Joan. V, 20). Verum Joannes Filium Dei, et verum Deum dicit: ergo si verus Deus, utique non creatus, nihil fallax habens atque fucatum, nihil confusum atque dissimile.
