Luther on Christ’s Real Presence in the Eucharist

Although Luther affirmed the substantial presence of Christ’s body and blood in the Eucharist, he disliked the doctrine of transubstantiation because it contradicts 1 Corinthians 10:16 which states that the bread and wine remain in the Lord’s Supper as the medium by which one receives Christ’s substantial body and blood.[1]  Luther considers the entire idea of transubstantiation an Aristotelian rationalization of the mystery of how the body and blood of Christ can become present through the bread and the wine.[2] 

In spite of this criticism of transubstantiation, it is interesting to note that Luther does not consider belief in the doctrine to be tremendously problematic and allows that people could still affirm transubstantiation as a theologoumenon.[3]  What is most important to the Reformer is that one affirms the substantial presence of Christ’s flesh and blood in the Lord’s Supper.  Although how one conceptually achieves this mysteriously physical presence is not unimportant, the main point for Luther is that one knows that Christ is substantially present in his body and blood “for you” (pro me).[4] 

This is why Luther was considerably less tolerant when it comes to the sacramental symbolicism of a figure like Zwingli.[5]  From Luther’s perspective, Zwingli ignores the divine promise that Christ’s flesh and blood will be present on essentially rationalistic grounds, namely, that physical bodies cannot be at more than one location at once.  As we have seen Luther rejects this logic and affirms that Jesus’ body remains a real body. However, it participates in God’s glory and can transcended the normal boundaries of physicality.[6]  After all, in the resurrection Jesus was able to walk through walls and appear and disappear at will.  Jesus’ body nevertheless remained a real body.  Christ could still invite Thomas to place his fingers in the nail holes of his very real hands and eat fish with the apostles.  Likewise, the mysterious supernatural quality of Christ’s body in the Lord’s Supper does not negate its real physicality or his genuine humanity. 

As we noted earlier, these differences between Luther and Zwingli on the sacrament are due in part to competing concepts of the communicatio idiomatum.[7]  Nevertheless, these differences also have implications regarding the nature of how the Word of God functions.  For Zwingli, the words of institution are signifiers that merely signify.[8]  Zwingli resolves the puzzle of how the signifiers “body and blood” can be validly applied to the signified “bread and wine” (which they do not match) through sacramental symbolicism.[9]  For Luther, divine words are not mere signifiers, but promises that effect what they speak.[10] This is the same principle that we have seen earlier in his views of confession and absolution.  Hence the words “this is my body . . . this is my blood” possess divine power to bring about the presence of Christ’s flesh and blood.[11]  Faith must simply trusts that God’s words perform what they promise.  To believe otherwise would be to trust in human reason over the God’s clearly stated promises.[12]

Sex and the Sacraments

Because our bodily presence and trustworthiness are inexorably tied together in human experience, physicality represents a key manner in which humans inculcate fidelity.  Physical intimacy within marriage best exemplifies this truth and is especially relevant to our study in light of the biblical motif of YHWH/Christ as the bridegroom to the people of God (Jer. 31:32, Isa. 54:5, Hos. 2:7, Eph. 5).  Christians have always rejected pre-marital sex and adultery not only because of the destructive consequences of disease and heartache, but because giving one’s self physically over to one’s spouse is the ultimate pledge of one’s loyalty and fidelity.  To give one’s body to another is to give one’s very being.  If one gives their very physical being away haphazardly, either for the sake of a pleasant weekend or in an affair, how can ultimate fidelity ever be established?[1]  If one gives away his very enfleshed self to anyone who strikes his fancy, nothing will be left over to give to one’s spouse as an ultimate pledge.  This is why the explanation that an act of infidelity was “just sex” is never convincing to the wronged partner. 

Therefore, bodily self-gift is a necessary means of giving assurance of fidelity to the absolute promise of Christ the bridegroom of the Church.  It is not sufficient to treat the sacraments as small, symbolic tokens of love in the manner of a husband who occasionally gives trinkets to his wife.[2]  Any relationship may be poorer without gestures like these small gifts, but a marriage is not a marriage in a biblical sense without fleshly consummation and unity (Gen. 2:24, Eph. 5:31).  Through fleshly self-giving one “knows” (yada) one’s spouse, that is, they gain a real participatory knowledge of their very physical being.  In the same manner, we can be no more certain of our justification and eternal life than to physically receive the very flesh and blood that was sacrificed for humanity on the cross (1 Cor. 11:26) and raised in anticipation of the general resurrection (Jn. 6:54).  There is no ambiguity as to whether or not one is justified by the work of Christ when Christ himself is present and gives believers that same body and blood that was sacrificed for them on the cross.  Just as baptism is a proleptic realization of the last judgment, so too paschal feast of the Lord’s Supper is the proleptic realization of the final bridal feast of the Lamb at the end of time (Rev. 19:6-9).

Intuitu Fidei in Orthodoxy and Pietism

This deviation from Luther and the teaching of the Formula of Concord came to be known as the teaching of intuitu fidei (“in view of faith”) and was eventually established the standard teaching of Lutheran Scholasticism with surprisingly little resistance.[1]  Lutherans generally held to the intuitu fidei teaching until the nineteenth century when the Neo-Lutheran movement rediscovered Luther’s doctrine of election.  In the United States, this rediscovery sparked the “Election Controversy” of the 1870s and 1880s fought between a series of midwestern German and Norwegian immigrant denominations.[2] 

The teaching of intuitu fidei had many difficulties, not least among them was that it was conceptually incoherent.  The premise of the Lutheran Scholastics remained that God actively created and sustained faith in Christians.[3]  What the teaching of intuitu fidei suggested was that God passive foreknew his own active work of communicating and sustaining the faith in the elect.  To say that God passively foreknew his own active work is absurd and incoherent.  Pastorally, the teaching proved to be a disaster because it held that believers could never genuinely possess assurance of their election, but only that God had at the present moment justified them if they were not actively resisting his grace.  The late Lutheran Scholastic David Hollaz baldly claimed that believers could never have full assurance of their salvation until their deathbed.[4]  Thus, intuitu fidei placed the accent very heavily on the human subject’s initiative in continuing to worthily cooperate with the divine grace offered in the means grace.  Indeed, it ultimately assumed that humans did indeed contribute something to their salvation.[5]  Inevitably, this teaching led to a return to the anxiety of whether one had appropriately cooperated with divine grace, albeit now following a line of reason anticipated by Melanchthon’s psychologization of faith.

In the last decades of the seventeenth century there emerged a tradition within Lutheranism called “Pietism.”[6]  Pietism is often seen as the antithesis of Scholastic Orthodoxy, with which it fought with for theological supremacy until well into the eighteenth century.[7]  Nevertheless, there is a continuity between the two theological traditions in that they both accorded a definitive role to the human subject in cooperating with divine grace.  Therefore, it is arguably the case that Pietism inherited Scholastic Orthodoxy’s problematic theology of sin and grace, and simply drove the disastrous pastoral implications intuitu fidei heresy to its logical conclusion.

Melanchthon Falls Into the Augustinian Dilemma

The older Melanchthon took Luther’s doctrine of the sacramentality of the word and reinterpreted it along the lines of the typical sacramentalist trajectory of the Augustinian Dilemma.  The Word of God is genuinely sacramental for Melanchthon in that it contains the coming of the Holy Spirit who works faith.  Nevertheless, in Melanchthon’s teaching it is at minimum a very strongly implied that the Holy Spirit’s work is dependent on the human will’s consent to cooperate.  Hence, in Melanchthon’s later work, grace can be construed as ultimately a possibility that is actualized by human decision.  Such a human decision can be called in question regarding its sincerity, thereby returning the sinner to the authenticity of his works (in this case, not external works, but rather a psychological event of conversion).  Therefore, the logical implication of the older Melanchthon’s theology of justification is that Luther’s unreflective faith is denied in favor an extremely reflective faith.  As we will see, the psychologizing of faith and the implicit call for self-examination as the sincerity of one’s conversion would become a standard feature in many strands of the later Protestant tradition.

Luther vs. Calvin on Justification and Election

Ultimately, those who embrace Luther’s theology find Calvin’s theology of election and justification so problematic because it fails to see that God is present and active in his Word in precisely the manner that he promises to be.  Calvin envisions human salvation and reprobation from the perspective of a comprehensive plan in eternity operating above and beyond the external Word.  The harmony of this plan can be discerned by looking past God’s words and coverings in order to see the whole of God’s hidden providence.[1]  Since some are saved and others not, God must not mean what he says when he wills the salvation of all who encounter him in the Word.  As a result, in Calvin’s theology the external Word may or may not do what it promises.  Only those who receive the inner call are truly elect and can see through the external word to God’s unified plan of grace for them as an individual.[2] 

By contrast, Luther sees God as exercising his rule through his Word manifest in and through his created masks.  Contrary to the claim of many Calvinists, Luther and the Lutheran tradition do not ultimately make God’s grace ineffective.  On the contrary, God’s Word always does precisely what it speaks.  However, God’s exercise of his reign is divided between a realm of law and a realm of grace. Those places where God has promised to work death and condemnation inexorably work death and condemnation.  By contrast, those who look for God in in the Word and sacraments will infallibly find a grace there that performs what it speaks.

Seen from the perspective of the sacramentality of the Word, the question of the perseverance of the saints is solved not on the basis of a special spiritual gift given to the elect (as in Augustine[3] and Calvin[4]), but on the basis on the efficacy of the means of grace external to the believer.[5]  God is always faithful to his Word regarding the means of grace.  The grace of the Word and the sacraments will inexorably move one toward the kingdom of heaven, just as a person who gets on a raft in the Mississippi River in Minnesota will inexorably move toward the Gulf of Mexico.[6] 

It could of course be objected that since Luther and the subsequent Lutheran tradition believe that apostasy is possible, one can never be genuinely certain that the divine Word will carry one along to their eschatological destiny.  In response, Lutherans have historically observed that God’s promise of grace is objectively true whether or not one believes in it.[7]  As we saw in Luther’s pronouncement regarding objective justification in an earlier chapter,[8] God’s promise of grace in Christ is more real than one’s refusal to believe it, and therefore remains a valid promise even if one chooses to actively reject it.[9]  Hence, to doubt the Word of the gospel is not to invalidate it, but rather to place one’s self outside of the realm of grace where the Word is operative and effective (i.e., the  sphere of the Church and its ministry), and into the realm of wrath and law which inexorably leads to eternal death (Rom. 3:20).  Hence, as long as one looks away from one’s present or possible future works and to God’s promise present in sphere of grace, one can always have infallible certainty that the living and active Word of the gospel will perform precisely what it speaks.
