10. The sum is, that the flesh and blood of Christ feed our souls just as bread and wine maintain and support our corporeal life. For there would be no aptitude in the sign, did not our souls find their nourishment in Christ. This could not be, did not Christ truly form one with us, and refresh us by the eating of his flesh, and the drinking of his blood. But though it seems an incredible thing that the flesh of Christ, while at such a distance from us in respect of place, should be food to us, let us remember how far the secret virtue of the Holy Spirit surpasses all our conceptions, and how foolish it is to wish to measure its immensity by our feeble capacity. Therefore, what our mind does not comprehend let faith conceive--viz. that the Spirit truly unites things separated by space. That sacred communion of flesh and blood by which Christ transfuses his life into us, just as if it penetrated our bones and marrow, he testifies and seals in the Supper, and that not by presenting a vain or empty sign, but by there exerting an efficacy of the Spirit by which he fulfils what he promises. And truly the thing there signified he exhibits and offers to all who sit down at that spiritual feast, although it is beneficially received by believers only who receive this great benefit with true faith and heartfelt gratitude. For this reason the apostle said, "The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ"? (1 Cor. 10:16.) There is no ground to object that the expression is figurative, and gives the sign the name of the thing signified. I admit, indeed, that the breaking of bread is a symbol, not the reality. But this being admitted, we duly infer from the exhibition of the symbol that the thing itself is exhibited. For unless we would charge God with deceit, we will never presume to say that he holds forth an empty symbol. Therefore, if by the breaking of bread the Lord truly represents the partaking of his body, there ought to be no doubt whatever that he truly exhibits and performs it. The rule which the pious ought always to observe is, whenever they see the symbols instituted by the Lord, to think and feel surely persuaded that the truth of the thing signified is also present. For why does the Lord put the symbol of his body into your hands, but just to assure you that you truly partake of him? If this is true let us feel as much assured that the visible sign is given us in seal of an invisible gift as that his body itself is given to us.

11. I hold then (as has always been received in the Church, and is still taught by those who feel aright), that the sacred mystery of the Supper consists of two things--the corporeal signs, which, presented to the eye, represent invisible things in a manner adapted to our weak capacity, and the spiritual truth, which is at once figured and exhibited by the signs. When attempting familiarly to explain its nature, I am accustomed to set down three things--the thing meant, the matter which depends on it, and the virtue or efficacy consequent upon both. The thing meant consists in the promises which are in a manner included in the sign. By the matter, or substance, I mean Christ, with his death and resurrection. By the effect, I understand redemption, justification, sanctification, eternal life, and all other benefits which Christ bestows upon us. Moreover, though all these things have respect to faith, I leave no room for the cavil, that when I say Christ is conceived by faith, I mean that he is only conceived by the intellect and imagination. He is offered by the promises, not that we may stop short at the sight or mere knowledge of him, but that we may enjoy true communion with him. And, indeed, I see not how any one can expect to have redemption and righteousness in the cross of Christ, and life in his death, without trusting first of all to true communion with Christ himself. Those blessings could not reach us, did not Christ previously make himself ours. I say then, that in the mystery of the Supper, by the symbols of bread and wine, Christ, his body and his blood, are truly exhibited to us, that in them he fulfilled all obedience, in order to procure righteousness for us-- first that we might become one body with him; and, secondly, that being made partakers of his substance, we might feel the result of this fact in the participation of all his blessings.

12. I now come to the hyperbolical mixtures which superstition has introduced. Here Satan has employed all his wiles, withdrawing the minds of men from heaven, and imbuing them with the perverse error that Christ is annexed to the element of bread. And, first, we are not to dream of such a presence of Christ in the sacrament as the artificers of the Romish court have imagined, as if the body of Christ, locally present, were to be taken into the hand, and chewed by the teeth, and swallowed by the throat. This was the form of Palinode, which Pope Nicholas dictated to Berengarius, in token of his repentance, a form expressed in terms so monstrous, that the author of the Gloss exclaims, that there is danger, if the reader is not particularly cautious, that he will be led by it into a worse heresy than was that of Berengarius (Distinct. 2 c. Ego Berengarius). Peter Lombard, though he labours much to excuse the absurdity, rathers inclines to a different opinion. As we cannot at all doubt that it is bounded according to the invariable rule in the human body, and is contained in heaven, where it was once received, and will remain till it return to judgment, so we deem it altogether unlawful to bring it back under these corruptible elements, or to imagine it everywhere present. And, indeed, there is no need of this, in order to our partaking of it, since the Lord by his Spirit bestows upon us the blessing of being one with him in soul, body, and spirit. The bond of that connection, therefore, is the Spirit of Christ, who unites us to him, and is a kind of channel by which everything that Christ has and is, is derived to us. For if we see that the sun, in sending forth its rays upon the earth, to generate, cherish, and invigorate its offspring, in a manner transfuses its substance into it, why should the radiance of the Spirit be less in conveying to us the communion of his flesh and blood? Wherefore the Scripture, when it speaks of our participation with Christ, refers its whole efficacy to the Spirit. Instead of many, one passage will suffice. Paul, in the Epistle to the Romans (Rom. 8:9ñ11), shows that the only way in which Christ dwells in us is by his Spirit. By this, however, he does not take away that communion of flesh and blood of which we now speak, but shows that it is owing to the Spirit alone that we possess Christ wholly, and have him abiding in us.
