In its present canonical form Philippians is, according to several scholars, a later collection of fragments of the correspondence of Paul with the congregation in Philippi that was founded by Paul himself. The first of the two major difficulties leading to this conclusion concerning redaction of the letter is created by a discrepancy between chapters 2 and 3—i.e., an entirely unexpected polemic in chapter 3 after a calm second chapter. Another major difficulty is the relationship of chapter 4, verses 10 and following, with Paul’s joyful acceptance of his suffering, and the remainder of the present letter that deals with the collection the Philippians had made and sent to Paul in prison. The place of the expression of Paul’s gratitude at the end of the letter is odd, particularly because Epaphroditus, the Philippian delegate conveying the gift, is thanked as though he had just arrived; yet he has already been described as ill when he was with Paul (who apologized in chapter 2 for not having told about Epaphroditus’ illness sooner and the delay in sending him back). Yet, Epaphroditus is obviously back and the sequence of events is, indeed, confusing.

The following rearrangement of the parts of the letter is probably acceptable. Chapter 4, verses 10–20, shows Paul reacting to the gift of the Philippians and the arrival of its bearer, Epaphroditus, and seems to be the earliest fragment, written probably during Paul’s imprisonment (c. 53–54). The portions of the letter that treat of the theme of mutual joy (1:1–3, 4:4–7, and probably 4:21–23 that refers back to chapter 1) are best taken together as fragments of a second and somewhat later letter. The third section is 3:2–4:3 and possibly 4:8–9, which addresses the danger caused by outsiders and opponents who had started to penetrate the Philippian congregation with a theology Paul considered heretical and against which he aimed his polemic. Because this is an entirely new situation, it is probably a third letter, of which only the preface is missing. This arrangement also attempts properly to account for the fact that chapter 4 actually comprises endings of several letters. Thus, chapter 3, verse 1, which is itself a summation and ending, fits in.

The reference to frequent visits between Paul and the Philippians referred to in the correspondence makes its origin in Rome unlikely and points rather toward Ephesus as the place of imprisonment. Paul’s reaction to the gift of the Philippians is almost rude (although he accepted gifts from no other congregation but preferred to support himself during his apostolic mission). He actually avoided expressing direct gratitude and attempted to divert the significance of the gift from its material side to its spiritual meaning. He emphasized the sympathy proven by the Philippians, the importance of the value of the gift for them as a spiritual sacrifice for God.

The “letter of joy” section describes Paul’s enthusiasm in his mission efforts—and their success—and his joy in the energy and growth of the mission in Philippi, which Paul shared with his congregation. Paul’s address to “bishops and deacons,” terms unique in Paul’s letters except here, are, perhaps, circumlocutions for missionaries active in Philippi, a congregation that had become a strong and stable Christian community. Paul had traditionally remained there about one week and, in chapters 1 and 2, encouraged and praised the Philippians for continuing in their faith in his absence. This is part of the thanksgiving in Philippians—an emphasis on the participation, cooperation, collaboration, and empathy of the Philippians with respect to the preaching of the gospel. Thus, the terms bishop and deacon may belong to the language of a self-supporting mission church with its own overseers (bishops) and workers (deacons) and does not carry the connotations of later ecclesiastical structures. Paul expressed his confidence in the fine beginning of this young church that sought “to become pure and blameless for the day of Christ,” the final judgment.

Paul then turned to his own experience of imprisonment, which he viewed as advancing the gospel. Though he considered that not all preachers of Christ preach on the basis of selfless motives, the fact that Christ is proclaimed is a most important cause for rejoicing. Paul then exhorted the Philippians to work hard for the sake of the gospel, not minding any opposition, and to do this in a sense of unity and mutual support.

This exhortation toward a strong and active sense of community was reinforced by quoting an early Christian hymn that described the humiliation (kenōsis) and exaltation of Jesus who is made the Lord of the universe and confessed by all cosmic powers. A part of Jesus’ humiliation, his death on the cross, can be taken as part of his manifest glorification. The verses following the hymn make clear that the incorporation of the hymn with its triumphal ending also has a missionary purpose, because Paul emphasized again the need to responsibly act out one’s own calling even before non-Christians. Thus, active responsibility continuously exercised in the perspective of the approaching Parousia merges with Paul’s own readiness to sacrifice himself.

In chapters 3–4 the situation may be totally different. Paul reacted to the threat of the appearance of Jewish-Christian missionaries who are rather close in theology to the Galatian Judaizers. Paul’s polemic indicates that in addition to Jewish tradition, they must have emphasized the Law in particular. Reference is made to circumcision, and Paul emphatically claimed that he could compete with heretics boasting of their Jewish tradition and, in elaborating on that, emphasized his former pious righteousness under the Law, in which he was blameless. He then stressed categorically that for him the experience of Christ has terminated his former piety completely and that he has left it behind as of no value. Such a polemic implies that for his opponents such was not the case. Paul also argued against libertinistic tendencies, which indicates that his opponents were not legalists in an ordinary sense but combined faithfulness to the Law with a strong and fanatical enthusiasm that could lead toward “mysticism” and easily be misinterpreted as libertinism. Paul’s emphasis on true Christian experience as not being completed but rather still being in the state of expectation might be a further polemic against overenthusiasm. In chapter 4, verse 8, Paul reaffirms his own example, making it, in imitation of the teaching of popular philosophy, the epitome of all positive ethical values and virtues, and thus the pattern to be imitated. This tendency toward the paradigmatic, together with warnings and autobiographical material in chapter 3, verse 2, to chapter 4, verse 3, can be seen as a “testament” of Paul, consciously written with an awareness of impending death or martyrdom. Thus Paul presents himself—his life, ideas, admonitions, and an eschatological section—as his heritage and as an incorporation of the message he preached and its value.
