Augustine of Hippo on Sex

St. Augustine’s desire for all earthly things, especially sex, became a problem.  Although it is often said that Augustine’s negative preoccupation with sex was the result of his youthful indiscretions, but this misses the larger reality of his Christian-Platonic worldview.  Indeed, when examined closely, Augustine’s youthful sexual dalliances and his later relationship with his unnamed mistress appear trite by modern standards.  Augustine admits that he lived with his mistress for nearly a decade as a common-law wife to whom he was faithful while raising a son.[1] Moreover, although celibacy was certainly a prized ideal in the early Church, Christian clergy and bishops regularly married in late Antiquity.[2]  That all Christians did not share Augustine’s negative attitude to sex is clearly demonstrated by his late debate with Julian of Eclanum.[3] 

Hence, from a strictly Christian moral standpoint (1 Cor. 7:38) there was no particular reason why marriage and lawful sexual activity was not an option open to Augustine.  Nevertheless, Augustine choose celibacy and insisted on the problematic nature of all sexual desire.  In light of this, it would be more accurate to see Augustine’s negative attitude toward sex as being a result of his desire to be a Christian-Platonic philosopher who sought the eternal over the distraction of the temporal.[4]  In discussing the matter in his Soliloquies (written just before his baptism) Augustine comments that he is committed to giving up sex completely in order to purely pursue the life of the mind.[5]

Hence, within Augustine’s Christian-Platonic framework, much as in the cosmic hierarchy the baser and more material is to be hierarchically ordered to the greater and more spiritual, so to the human heart should be ordered to the eternal and spiritual, and not to enjoyment the temporal.[6]  Indeed, in the pre-lapsarian state, the baser desires did not interfere with the exercise of reason.  Adam and Eve would not have enjoyed or even desired sex, but instead would have engaged in the sex-act purely for the rational purposes of reproduction.[7]  The orderly nature of the cosmos- where the material was subordinate the spiritual- would have been reproduced in the human heart as a microcosm of the macrocosm.  Adam and his bride would have never burned with desire for one another but would have simply called their genitals to attention by an act of will, engaged in reproductive act without pleasure, and deactivated their genitals just as easily.[8] 

Augustine saw his own struggle to quiet his sexual desires and live a life unadulterated life of reason to be symptom of the Fall.  Sinful desire which interferes with reason (concupiscence) is a punishment for sin.[9]  Just creation is in revolt against the creator, so too the desires of the fallen person are at war with the rational and spiritual centers of the self: “In short, to say all in a word, what but disobedience was the punishment of disobedience in that sin? For what else is man’s misery but his own disobedience to himself, so that in consequence of his not being willing to do what he could do, he now wills to do what he cannot?”[10] 

Even without sin, created being is inherently unstable.[11]  Creation comes from nothingness and has a tendency of drifting back into nothingness.[12]  For this reason, humans and angels are in need of grace to prop them up even in their state of integrity.[13]  Only by receiving a special grace can humans and angels not drift back into nothingness through falling into sin.[14]  In Augustine’s thought- much as in later Roman Catholicism- although “grace” (gratia) certainly comes by God’s undeserved favor (i.e., the Pauline charis), it is primarily defined as God’s supernatural assistance and self-communication to his rational creatures in order that they might achieve higher and greater degrees of moral regeneration.[15]

Creation by Word

Central to the biblical narrative is the creative and redemptive power of the Word of God.  God calls both the old and new creation into existence by means of his efficacious word (creatio per verbum).  This is why Oswald Bayer, in his exposition of Luther’s doctrine of creation has argued that creation itself is a form of justification.[1]  In calling creation into existence, God judicially affirms its status and identity as his good creation.  Moreover, just as Christians are justified and sanctified by the work of the Word and the Spirt (Jn. 3:5, Eph. 5:26), so too creation comes about by way of God speaking his Word in the power of the Spirit: “By the word of the LORD the heavens were made, and by the breath of his mouth all their host” (Ps. 33:6).  As Luther observes in his Genesis commentary, this makes creatures created words in analogy to God’s eternal created Word: “By speaking, God created all things and worked through his Word.  All his works are words of God, created by the uncreated Word.”[2] 

Much like human words, God’s Word possesses a number of different dimensions.  Scriptures speak of God’s will and reality as being revealed by his Word.  Indeed, the idea of the Word of God as the “testimony” of God’s previous creative and redemptive acts is of central importance in the Bible (Ps. 71:15-18, 119:46, 2 Tim. 1:8, 1 Jn. 1:1-4, Rev. 12:11).[3]  In John’s Gospel, Jesus is consistently described as the true and eternal Word of God because he reveals and represents the Father (Jn. 14:9).  Luther in his own writings referred to this dimension of the divine Word as “Call-Words” (Heissel-Wort).[4]  Call-words are signifiers that signify states of affairs are already an actuality. 

The second dimension of God’s Word is its efficacious nature.  The word functions in such a way so as not merely to testify to states of affairs that already are actualized (testimony), but to call into existence new realities.  Luther called this phenomenon “Deed-Words” (Thettel-Wort).[5]  God calls creation into existence (Gen. 1), Jesus heals by his word, and the word of the disciples forgives and binds sins because of Jesus’ divine promise and command (Jn. 20).  Human language functions analogously when effective statements are made such as: “I pronounce you man and wife” or “I bestow this office upon you.”  This efficacious quality of language is what is encompassed in what modern speech-act theory has parsed into the categories of “Illocutionary” and “Perlocutionary” speech.[6]

Justification by the Word

In spite of this historic division between Roman Catholics and Protestants on the question of justification, there has been an unanimity of focus in both groups on the subjective reception of the righteousness of God.  That is to say, both Roman Catholics and Protestants have historically tended to center their theologies of justification on what steps individuals must take to appropriate the merit of Christ.  Catholics have debated amongst themselves the necessity or lack of necessity of a certain disposition to divine grace as much as Protestants have debated free will and the signs of authentic conversion.1  Within the Protestant tradition, these debates are rather ironic in light of the Magisterial Reformation’s emphasis on the externality and unconditionality of grace. 

Particularly with regard to the historic Protestant tradition, this point has been made forcefully by Philip Cary in his essay: “Why Luther is not quite Protestant: The Logic of Faith in a Sacramental Promise.”2  When dealing with justification in the theology of Luther and comparing to the subsequent Protestantism, Cary observes that most Protestants have focus on the reality of faith.  In this, faith and its authenticity are considered the decisive factor.  This gives rise to the soteriological syllogism that Cary outlines thus: “Major Premise:  Whoever believes in Christ is saved.  Minor Premise:  I believe in Christ. Conclusion: I am saved.”3  Of course, the raises the problem of how one knows that they have authentic faith.  Many Protestants have therefore been fixated on discovering secondary signs that confirm the authenticity of faith: a particular kind of conversion experience, good works, wealth, personal holiness or spiritual gifts, and perhaps even snake handling!

When turning to Luther’s theology, Cary observes that the focus shifts from the authenticity of faith to the authenticity of God’s promise made concrete and tangible in the means of grace.  Thus, Cary renders Luther’s soteriological syllogism thus: “Major premise:  Christ told me, “I baptize you in the name of the Father, Son and Holy Spirit.” Minor premise:  Christ never lies but only tells the truth.  Conclusion: I am baptized (i.e., I have new life in Christ).”4

As Cary correctly observes, although both Luther and the larger Protestant tradition do certainly agree that one receives justification through faith, there is a subtle, yet highly significant difference between the two understandings of the righteousness of faith.  Whereas most Protestants hold that faith should be reflective regarding its own authenticity, Luther believes in what Cary characterizes as an “unreflective faith,” that is, a faith that does not focus on the question of its own authenticity.5

According to Cary, this unreflective faith is possible for Luther because of his belief in the sacramentality of the word.6  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.7  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 their authenticity of their faith is seen by Luther as a sinful resistance to Jesus’ 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.”

The Imputation of Righteousness and our Future-Present Justification

Although justification is pronounced objectively in the resurrection (Rom. 4:25), it is received subjectively through faith that hears the promise: “For with the heart one believes and is justified, and with the mouth one confesses and is saved . . . [And] faith comes from hearing, and hearing through the word of Christ” (Rom. 10:10, v. 17).  No one can have faith apart from the electing and regenerative work of the Spirit (1 Cor. 2:14, 12:3, Gal. 3:2).  Christ makes intercession on behalf of believers in heaven, on the basis of his sacrifice on the cross (Rom. 8:34).  The Holy Spirit, the who is the spirit of the Son (Gal. 4:6), makes the fruits of Christ’s intercession – justification – present in the heart of the believer (Rom. 10:6-13) through the hearing of the Word (Rom. 10:7, Gal. 3:2).  Much as the elect representational persons stood in the place of Israel in the Old Testament as mediators, so too Christ and his righteousness stand in for the unrighteousness of the unbeliever through an act of imputation (Rom. 3:25, 4:9, v. 22, 8:10, 1 Cor. 1:30, 2 Cor. 5:21, Gal. 3:6, Phil. 3:9).  The concept of representation that we see in the Old Testament therefore makes sense of Paul’s language of imputation in atonement and justification.  In atonement, Christ is imputed with human sin, and in justification humans are imputed with Christ’s righteousness (2 Cor. 5:21).

It is important to notice that Paul uses the term eschatological term “justification” for what happens proleptically (in the future) to believers in the present.  As we observed earlier, for Second Temple Jews, at the end of time God would “justify” (judge righteous and vindicate) those who had adhered to the covenant and usher them into the kingdom.  For Paul, Christ is the object of election and justification.  He is one the one who has adhered to the covenant and be vindicated on the eschatological day of his resurrection.  Therefore, in the present believers can proleptically receive through Christ what they will receive at the end of time through faith in the promise (i.e., election and justification).  This is because the eschaton has already happened for Christ, and therefore when believers enter into him the eschaton happens to them as well.  Outwardly, believers remain in the current age weighed down by sin and death, but in the inner being they already have been ushered into the kingdom of the resurrected: “But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness” (Rom. 8:10).
