Luther On Christ’s Substantial Eucharistic Presence For You

The gospel is a unilateral divine self-donation, in that an unconditional promise means a gift of the promiser himself in order to fulfill the terms of the promise. Therefore, Christians who receive the unilateral promise of the gospel are heirs to Christ’s very sacrificed person as a guarantee that he is at their disposal to fulfill his promise. This means that through the promise of the gospel we inherit Christ and everything that he possesses. Indeed, as Paul states, all true believers in union with Christ are “fellow heirs with Christ” (Rom 8:17). This reality is manifest in the Lord’s Supper wherein Christ wills his very physical being (body and blood) through which he brought salvation to believers. Therefore, to paraphrase Luther, in dying Jesus gives the inheritance of his body and blood to believers in order that they might receive the forgiveness of sins and eternal life through his promise attached to them.1

Returning to On the Babylonian Captivity of the Church, Luther’s second major difficulty with the medieval conception of the Eucharist is the doctrine of transubstantiation.2 The doctrine of transubstantiation teaches that the bread and the wine in the Lord’s Supper are transformed by the words of institution into the body and blood of Christ, although the outward appearance and qualities of bread and wine (Aristotelian “accidents”) remain intact.3 Although Luther affirmed the substantial presence of Christ’s body and blood in the Eucharist, he disliked the doctrine of transubstantiation the 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.4 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.5

Justification by the Word

Lexham Press will be publishing my newest book, Justification by the Word: Restoring Sola Fide, relatively soon. If interested, you can pre-order at Lexham’s website. Here’s a snippet from the introduction:

According to [Phillip] Cary, this unreflective faith is possible for Luther because of his belief in the sacramentality of the word.1 Here Cary echoes the work of the German Luther scholar Oswald Bayer, who claims that it was in fact the sacramentality of the word, and not justification by faith, that was central to the so-called Reformation breakthrough.2 The word of justification is objectified in both in preaching and the sacraments in such a way as to shift the focus from authentic appropriation of God’s grace to the question of the surety of God’s promise. Since the risen Jesus is genuinely present in the means of grace, he is capable of mediating a direct assurance of his justifying grace for sinners who look for him there. The tendency of believers to reflect upon and worry about the authenticity of their faith is seen by Luther as a sinful resistance to Jesus’s promise that they have already been accepted. Therefore, instead of “justification through faith” it might be appropriate to characterize Luther’s position as “justification by the word.”

In this book, we will endeavor to show that, although it has been neglected and misunderstood by Protestants and Catholics alike, Luther’s “justification by the word” is a better model for understanding salvation in Christ. It will be argued that this is not only the case because it is more faithful to the teachings of the Scriptures, but also because it is the only doctrine of salvation that fully succeeds in de-centering the self and overcoming the self-incurvature of sin (incurvatus in se). As Luther himself observes in his Galatians commentary of 1531: “This is the reason why our theology is certain, it snatches us away from ourselves and places us outside ourselves, so that we do not depend on our own strength, conscience, experience, person, or works but depend on that which is outside ourselves, that is, on the promise and truth of God, which cannot deceive.”3
