Chapter IX.

In order that no one through observing the outward part should waver in faith, many instances are brought forward wherein the outward nature has been changed, and so it is proved that bread is made the true body of Christ. The treatise then is brought to a termination with certain remarks as to the effects of the sacrament, the disposition of the recipients, and such like.

50. Perhaps you will say, “I see something else, how is it that you assert that I receive the Body of Christ?” And this is the point which remains for us to prove. And what evidence shall we make use of? Let us prove that this is not what nature made, but what the blessing consecrated, and the power of blessing is greater than that of nature, because by blessing nature itself is changed.

51. Moses was holding a rod, he cast it down and it became a serpent.62    Ex. iv. 3, 4. Again, he took hold of the tail of the serpent and it returned to the nature of a rod. You see that by virtue of the prophetic office there were two changes, of the nature both of the serpent and of the rod. The streams of Egypt were running with a pure flow of water; of a sudden from the veins of the sources blood began to burst forth, and none could drink of the river. Again, at the prophet’s prayer the blood ceased, and the nature of water returned.63    Ex. vii. 20 ff. The people of the Hebrews were shut in on every side, hemmed in on the one hand by the Egyptians, on the other by the sea; Moses lifted up his rod, the water divided and hardened like walls, and a way for the feet appeared between the waves.64    Ex. xiv. 21 ff. Jordan being turned back, returned, contrary to nature, to the source of its stream.65    Josh. iii. 16. Is it not clear that the nature of the waves of the sea and of the river stream was changed? The people of the fathers thirsted, Moses touched the rock, and water flowed out of the rock.66    Ex. xvii. 6. Did not grace work a result contrary to nature, so that the rock poured forth water, which by nature it did not contain? Marah was a most bitter stream, so that the thirsting people could not drink. Moses cast wood into the water, and the water lost its bitterness, which grace of a sudden tempered.67    Ex. xv. 25. In the time of Elisha the prophet one of the sons of the prophets lost the head from his axe, which sank. He who had lost the iron asked Elisha, who cast in a piece of wood and the iron swam. This, too, we clearly recognize as having happened contrary to nature, for iron is of heavier nature than water.

52. We observe, then, that grace has more power than nature, and yet so far we have only spoken of the grace of a prophet’s blessing. But if the blessing of man had such power as to change nature, what are we to say of that divine consecration where the very words of the Lord and Saviour operate? For that sacrament which you receive is made what it is by the word of Christ. But if the word of Elijah had such power as to bring down fire from heaven, shall not the word of Christ have power to change the nature of the elements? You read concerning the making of the whole world: “He spake and they were made, He commanded and they were created.”68    Ps. iii. 5. Shall not the word of Christ, which was able to make out of nothing that which was not, be able to change things which already are into what they were not? For it is not less to give a new nature to things than to change them.

53. But why make use of arguments? Let us use the examples He gives, and by the example of the Incarnation prove the truth of the mystery. Did the course of nature proceed as usual when the Lord Jesus was born of Mary? If we look to the usual course, a woman ordinarily conceives after connection with a man. And this body which we make is that which was born of the Virgin. Why do you seek the order of nature in the Body of Christ, seeing that the Lord Jesus Himself was born of a Virgin, not according to nature? It is the true Flesh of Christ which crucified and buried, this is then truly the Sacrament of His Body.

54. The Lord Jesus Himself proclaims: “This is My Body.”69    S. Matt. xxvi. 26. Before the blessing of the heavenly words another nature is spoken of, after the consecration the Body is signified. He Himself speaks of His Blood. Before the consecration it has another name, after it is called Blood. And you say, Amen, that is, It is true. Let the heart within confess what the mouth utters, let the soul feel what the voice speaks.

55. Christ, then, feeds His Church with these sacraments, by means of which the substance of the soul is strengthened, and seeing the continual progress of her grace, He rightly says to her: “How comely are thy breasts, my sister, my spouse, how comely they are made by wine, and the smell of thy garments is above all spices. A dropping honeycomb are thy lips, my spouse, honey and milk are under thy tongue, and the smell of thy garments is as the smell of Lebanon. A garden enclosed is my sister, my spouse, a garden enclosed, a fountain sealed.”70    Cant. iv. 10 ff. By which He signifies that the mystery ought to remain sealed up with you, that it be not violated by the deeds of an evil life, and pollution of chastity, that it be not made known to thou, for whom it is not fitting, nor by garrulous talkativeness it be spread abroad amongst unbelievers. Your guardianship of the faith ought therefore to be good, that integrity of life and silence may endure unblemished.

56. For which reason, too, the Church, guarding the depth of the heavenly mysteries, repels the furious storms of wind, and calls to her the sweetness of the grace of spring, and knowing that her garden cannot displease Christ, invites the Bridegroom, saying: “Arise, O north wind, and come, thou south; blow upon my garden, and let my ointments flow down. Let my Brother come down to His garden, and eat the fruit of His trees.”71    Cant. iv. 15; v. 1. For it has good trees and fruitful, which have dipped their roots in the water of the sacred spring, and with fresh growth have shot forth into good fruits, so as now not to be cut with the axe of the prophet, but to abound with the fruitfulness of the Gospel.

57. Lastly, the Lord also, delighted with their fertility, answers: “I have entered into My garden, My sister, My spouse; I have gathered My myrrh with My spices, I have eaten My meat with My honey, I have drunk My drink with My milk.”72    Cant. v. 1. Understand, you faithful, why He spoke of meat and drink. And there is no doubt that He Himself eats and drinks in us, as you have read that He says that in our persons He is in prison.73    S. Matt. xxv. 36.

58. Wherefore, too, the Church, beholding so great grace, exhorts her sons and her friends to come together to the sacraments, saying: “Eat, my friends, and drink and be inebriated, my brother.”74    Cant. v. 1. What we eat and what we drink the Holy Spirit has elsewhere made plain by the prophet, saying, “Taste and see that the Lord is good, blessed is the man that hopeth in Him.”75    Ps. xxxiv. [xxxiii.] 9. In that sacrament is Christ, because it is the Body of Christ, it is therefore not bodily food but spiritual. Whence the Apostle says of its type: “Our fathers ate spiritual food and drank spiritual drink,”76    1 Cor. x. 3. for the Body of God is a spiritual body; the Body of Christ is the Body of the Divine Spirit, for the Spirit is Christ, as we read: “The Spirit before our face is Christ the Lord.”77    Lam. iv. 20. And in the Epistle of Peter we read: “Christ died for us.”78    1 Pet. ii. 21. Lastly, that food strengthens our heart, and that drink “maketh glad the heart of man,”79    Ps. civ. [ciii.] 15. as the prophet has recorded.

59. So, then, having obtained everything, let us know that we are born again, but let us not say, How are we born again? Have we entered a second time into our mother’s womb and been born again? I do not recognize here the course of nature. But here there is no order of nature, where is the excellence of grace. And again, it is not always the course of nature which brings about conception, for we confess that Christ the Lord was conceived of a Virgin, and reject the order of nature. For Mary conceived not of man, but was with child of the Holy Spirit, as Matthew says: “She was found with child of the Holy Spirit.”80    S. Matt. i. 18. If, then, the Holy Spirit coming down upon the Virgin wrought the conception, and effected the work of generation, surely we must not doubt but that, coming down upon the Font, or upon those who receive Baptism, He effects the reality of the new birth.

CAPUT IX.

Ne quis externa perculsus specie, in fide fluctuet, plurimis exemplis, quibus mutatam aut victam fuisse naturam constat, in medium allatis, e pane veram Christi carnem fieri evincit. Postremo nonnullis quae ad effectus ejus, utentium dispositiones ac similia pertinent, figurate propositis, tractatum claudit.

50. Forte dicas: Aliud video, quomodo tu mihi 0405C asseris quod Christi corpus accipiam? Et hoc nobis adhuc superest ut probemus. Quantis igitur utimur exemplis! Probemus non hoc esse quod natura formavit, sed quod benedictio consecravit: majoremque vim esse benedictionis quam naturae; quia benedictione etiam natura ipsa mutatur.

51. Virgam tenebat Moyses, projecit eam, et facta est serpens (Exod. IV, 3, 4). Rursus prehendit caudam serpentis, et in virgae naturam revertit. Vides igitur prophetica gratia bis mutatam esse naturam et 0406A serpentis et virgae? Currebant Aegypti flumina puro aquarum meatu, subito de fontium venis sanguis coepit erumpere; et non erat potus in fluviis (Exod. VII, 20 et seq.). Rursus a prophetae prece cruor cessavit fluminum, aquarum natura remeavit. Circumclusus undique erat populus Hebraeorum, hinc Aegyptiis vallatus, inde mari clausus: virgam levavit Moyses, separavit se aqua, et in murorum specie congelavit, atque inter undas via pedestris apparuit (Exod. XIV, 21 et seq.). Jordanis retrorsum conversus contra naturam in sui fontis revertit exordium (Jos. III, 16). Nonne claret naturam vel maritimorum fluctuum vel fluvialis cursus esse mutatam? Sitiebat populus patrum, tetigit Moyses petram, et aqua de petra fluxit. Numquid non praeter naturam operata est gratia, ut 0406B aquam vomeret petra, quam non habebat natura? Merrha fluvius amarissimus erat, ut sitiens populus bibere non posset. Misit Moyses 339 lignum in aquam, et amaritudinem suam aquarum natura deposuit (Exod. XV, 23 et seq.), quam infusa subito gratia temperavit. Sub Elisaeo propheta uni ex filiis prophetarum excussum est ferrum de securi, et statim mersum est. Rogavit Elisaeum, qui amiserat ferrum: misit etiam Elisaeus lignum in aquam, et ferrum natavit (IV Reg. VI, 6). Utique et hoc praeter naturam factum cognoscimus; gravior est enim ferri species, quam aquarum liquor.

52. Advertimus igitur majoris esse virtutis gratiam quam naturam, et adhuc tamen propheticae benedictionis numeramus gratiam? Quod si tantum 0406C valuit humana benedictio, ut naturam converteret (III Reg. XVIII, 38); quid dicimus de ipsa consecratione divina, ubi verba ipsa Domini Salvatoris operantur? Nam sacramentum istud quod accipis, Christi sermone conficitur. Quod si tantum valuit sermo Eliae, ut ignem de coelo deponeret: non valebit Christi sermo, ut species mutet elementorum? De totius mundi operibus legisti: Quia ipse dixit, et facta sunt: ipse mandavit, et creata sunt (Psal. CXLVIII, 5. De Consec., dist. 2, c. In quibus, § Cujus 0407A clare); sermo ergo Christi qui potuit ex nihilo facere quod non erat, non potest ea quae sunt, in id mutare, quod non erant? Non enim minus est novas rebus dare, quam mutare naturas.

53. Sed quid argumentis utimur? Suis utamur exemplis, incarnationisque exemplo astruamus mysterii veritatem. Numquid naturae usus praecessit, cum Jesus Dominus ex Maria nasceretur? Si ordinem quaerimus, viro mixta femina generare consuevit. Liquet igitur quod praeter naturae ordinem Virgo generavit. Et hoc quod conficimus corpus, ex Virgine est: quid hic quaeris naturae ordinem in Christi corpore, cum praeter naturam sit ipse Dominus Jesus partus ex Virgine? Vera utique caro Christi, quae crucifixa est, quae sepulta est: vere ergo carnis illius sacramentum est.

0407B 54. Ipse clamat Dominus Jesus: Hoc est corpus meum (Matth. XXVI, 26). Ante benedictionem verborum coelestium alia species nominatur, post consecrationem corpus significatur (De Consec. dist. 10, § Haec et his). Ipse dicit sanguinem 340 suum. Ante consecrationem aliud dicitur, post consecrationem sanguis nuncupatur. Et tu dicis: Amen, hoc est, verum est. Quod os loquitur, mens interna fateatur: quod sermo sonat, affectus sentiat.

55. His igitur sacramentis pascit Ecclesiam suam Christus, quibus animae firmatur substantia: meritoque videns profectum ejus gratiae continentem, dicit ad eam: Quam decora facta sunt ubera tua, soror mea sponsa! Quam decora facta sunt a vino: et odor vestimentorum tuorum super omnia aromata! Favus distillans 0407C labia tua, o sponsa, mel et lac sub lingua tua, et odor vestimentorum tuorum sicut odor Libani. Hortus conclusus, soror mea sponsa, hortus conclusus, fons signatus (Cant. IV, 10 et seq.). Quo significat signatum debere apud te manere mysterium, ne violetur operibus malae vitae, atque adulterio castitatis, ne divulgetur quibus non convenit, ne garrula loquacitate dispergatur in 0408A perfidos. Bona ergo debet esse fidei tuae custodia, ut intemerata vitae ac silentii integritas perseveret.

56. Unde et Ecclesia altitudinem servans mysteriorum coelestium, rejicit a se graviores venti procellas, et invitat vernantis gratiae suavitatem: et sciens quod hortus suus Christo displicere non possit, ipsum advocat Sponsum dicens: Exsurge aquilo, et veni auster: perfla hortum meum, et defluant unguenta mea (Ibid., 16). Descendat frater meus in hortum suum, et edat fructum pomiferarum suarum (Cant. V, 1). Bonas enim arbores et fructiferas habet, quae radices suas tinxerint sacri fontis irriguo, et in bonos fructus novae fecunditatis germine pullulaverint; ut non jam prophetica caedantur securi, sed Evangelica ubertate fecundentur (Matth. III, 10).

0408B 57. Denique fertilitate earum etiam Dominus delectatus respondet: Ingressus sum in hortum meum, soror mea Sponsa: vindemiavi myrrham meam cum unguentis meis, manducavi cibum meum cum melle meo, bibi potum meum cum lacte meo (Cant. V, 1). Quare cibum et potum dixerit, fidelis intellige. Illud autem non dubium, quod in nobis 341 ipse manducat et bibit, sicut in nobis legisti quia in carcere esse se dicit (Matth. XXV, 36).

58. Unde et Ecclesia videns tantam gratiam, hortatur filios suos, hortatur proximos, ut ad sacramenta concurrant, dicens: Edite proximi mei, et bibite, et inebriamini, fratres mei (Cant. V, 1). Quid edamus, quid bibamus, alibi tibi per Prophetam 0408C Spiritus sanctus expressit dicens: Gustate et videte quoniam suavis est Dominus: beatus vir qui sperat in eo (Psal. XXXIII, 9). In illo sacramento (De Consec. dist. 2, cap., In illo sacram.) Christus est; quia corpus est Christi: non ergo corporalis esca, sed spiritalis est. Unde et Apostolus de typo ejus ait: Quia patres nostri escam spiritalem manducaverunt, et potum spiritalem biberunt (I Cor. X, 3); corpus enim 0409A Dei corpus est spiritale: corpus Christi corpus est divini Spiritus; quia Spiritus Christus, ut legimus: Spiritus ante faciem nostram Christus Dominus (Thren. IV, 20). Et in Petri Epistola habemus: Christus pro nobis mortuus est (I Pet. II, 21). Denique cor nostrum esca ista confirmat, et potus iste 342 laetificat cor hominis, ut Propheta memoravit (Psal. CIII, 15).

59. Unde adepti omnia, sciamus regeneratos nos esse: nec dicamus, quomodo regenerati sumus? Numquid in ventrem matris nostrae introivimus, et renati sumus? non agnosco usum naturae. Sed nullus 0410A hic naturae ordo, ubi excellentia gratiae est. Denique non semper usus naturae generationem facit: generatum ex Virgine Christum Dominum confitemur, et naturae ordinem denegamus. Non enim ex viro Maria concepit: sed de Spiritu sancto in utero accepit, ut dicit Matthaeus: Quia inventa est in utero habens de Spiritu sancto (Matth. I, 18). Si ergo superveniens Spiritus sanctus in Virginem, conceptionem operatus est, et generationis munus implevit: non utique dubitandum est quod superveniens in fontem, vel super eos qui baptismum consequuntur, veritatem regenerationis operetur.
