Notes on Epistle of Barnabas 15 and Christians Worshiping on a Sunday ("eight day") vs. the Jewish Sabbath

  

πέρας γέ τοι λέγει αὐτοῖς· Τὰς νεομηνίας ὑμῶν καὶ τὰ σάββατα οὐκ ἀνέχομαι. ὁρᾶτε, πῶς λέγει; οὐ τὰ νῦν σάββατα ἐμοὶ δεκτά, ἀλλὰ ὃ πεποίηκα, ἐν ᾧ καταπαύσας τὰ πάντα ἀρχὴν ἡμέρας ὀγδόης ποιήσω, ὅ ἐστιν ἄλλου κόσμου ἀρχήν.  διὸ καὶ ἄγομεν τὴν ἡμέραν τὴν ὀγδόην εἰς εὐφροσύνην, ἐν ᾗ καὶ ὁ Ἰησοῦς ἀνέστη ἐκ νεκρῶν καὶ φανερωθεὶς ἀνέβη εἰς οὐρανούς.

 

 

Finally, he says to them: “I cannot stand your new moons and sabbaths.” You see what he means: it is not the present sabbaths that are acceptable to me, but the one that I have made, on that sabbath, after I have set everything at rest, I will create the beginning of an eighth day, which is the beginning of another world. This is why we spend the eighth day in celebration, the day on which Jesus both arose from the dead and, after appearing again, ascended into heaven. (Epistle of Barnabas 15:8-9 | Michael W. Holmes translation)

 

 

Barnabas’ version of the Sabbath commandment (15:1, 6) is original; he interprets “sanctifying” the Sabbath as an activity of radical moral holiness such as no one in the present evil age can attain. In the eschatological Sabbath, however, Christians themselves will have been fully sanctified and so will be able to keep holy the Sabbath (age) and share the eschatological rest of God. Obedience to the Sabbath commandment has nothing to do with a day of the week or with physical rest but is a matter of holy living in the future Sabbath age that God has made holy. Jewish Sabbaths (τὰ νῦν σάββατα) are therefore quite unacceptable to God.

 

At this point Barnabas’ argument might have ended. Much of the confusion about his meaning has arisen from his concluding remarks about the “eighth day,” which have almost the character of an afterthought. Not content with dismissing weekly Sabbath observance by reference to the eschatological Sabbath, Barnabas (like Ignatius before him) feels it necessary also to contrast the Jewish Sabbath with the Christian Sunday. He therefore complicates his eschatological terminology by referring to the new world as the “eighth day,” and concludes, “Therefore (i.e., because the Sabbath acceptable to God is the eschatological eighth day, the new world), we pass with rejoicing the eighth day on which Jesus rose from the dead, appeared, and ascended into heaven” (15:9).

II.8.a. The Sabbath (Barn. 15.1–9)

 

The introduction of new material with the conjunctive phrase, “Moreover, therefore” (ἔτι οὖν καί; 15.1) clearly indicates a break in thought as Barnabas introduces a new section. The topic is introduced with a prepositional phrase: “about the Sabbath” (περὶ τοῦ σαββάτου). Given the centrality of 13.1–14.9 to the theological thought of the letter and the introduction of 15.1 with a phrase that indicates additional matters, it is tempting to view the following discussion as an appendix. Yet two arguments suggest that 15.1–9 plays a more vital role in the letter than that of an appendix. First, Barnabas has employed similar transitional phrases elsewhere in the letter. He transitions to topics that play an important theological role in the letter in 4.6 and 5.5 with the conjunctions ἔτι δὲ καί. The use of a similar transition in portions of the letter that are integral to the author’s theological thought warns against viewing 15.1–9 as an appendix. Second, Barnabas links the discussion of the Sabbath to the Sinai narrative that plays a pivotal role in 4.6–8 and 14.1–5. The Sabbath command is found in the Ten Words (15.1), which were written on the two tablets that Moses broke when he saw the Israelites’ idolatry (4.7–8; 14.2–3). God entrusted these words to Moses, who was able to receive the covenant despite the Israelites’ failure (14.4; 15.1). Finally, the words were given at Sinai (15.1), which provides the unstated setting for the events narrated in the previous section (14.1–5). The following considerations about Sabbath practice are thus to be viewed alongside what the author has previously written.

 

Barnabas lays out the scriptural basis for a right understanding of Sabbath in 15.1–3, and these verses will be the source from which the rest of the argument flows. God spoke to Moses face to face in order to tell the people that they should sanctify the Lord’s Sabbath “with pure hands and pure hearts” (χερσὶν καθαραῖς καὶ καρδίᾳ καθαρᾷ; Barn. 15.1). The language of sanctification is found in Exod 20:8 and Deut 5:12, 15, but the verb appears as an infinitive complement rather than an imperative in Greek translations of the Torah. The pure hands and heart that Barnabas lists as the means by which to sanctify the Sabbath are not listed in Exod 20 and Deut 5. Someone who is “innocent with regard to hands” (ἀθῷος χερσίν) and “pure with regard to heart” (καθαρὸς τῇ καρδίᾳ) is able to ascend the Lord’s mountain in Ps 23:4 (24:4 MT).303 Barnabas appears to employ a variation of the Sabbath commandment that is not found in the Torah. He also appeals to a promise from God that God’s mercy will be upon those who keep the Sabbath (Barn. 15.2). Although the citation is introduced as a word from God to Moses, Barnabas employs language that comes from Exod 31:13–17; Jer 17:24–25. The words in the second quotation of this section are again not found in exactly this form in Greek Jewish scriptures. Barnabas locates the meaning of Sabbath in Genesis: God “speaks about Sabbath at the beginning of creation” (τὸ σάββατον λέγει ἐν ἀρχῇ τῆς κτίσεως; Barn. 15.3). God worked in six days, completed his work on the seventh, and rested on the seventh. Barnabas’s citation comes from Gen 2:2–3.

 

Having established the scriptural basis for his discussion of the Sabbath, Barnabas turns to interpretation in 15.4–7. He begins by urging his audience to pay attention to specific lines regarding God’s actions on the seventh day. As in the epistolary greeting (1.1), he refers to his audience as children (τέκνα), thereby drawing attention to his close relationship with the audience and to his authority over them (15.4). Barnabas interprets God’s completion of creation in six days with reference to Ps 89:4 (90:4 MT). In order to do this, however, Barnabas rearranges the verbal phrases from (Gen 2:2–3 [Barn. 15.3]). The citation in Barn. 15.3 notes that God made (ἐποίησεν) the works of his hands in six days and finished (συνετέλεσεν) it on the seventh day. In the analysis of Barn. 15.4, Barnabas shuffles the verbs so that God finished (συνετέλεσεν) the work in six days. The work of creation is then extended to include “all things” (τὰ σύμπαντα) so that God will complete all things in six days. If a day with the Lord is like 1,000 years and God completed things in six days, Barnabas reasons that all things on earth will be completed in 6,000 years. God’s rest on the Sabbath is then taken with reference to the parousia of the Son. The seventh day will be a day for God’s true rest as the Son brings the time of the lawless one to an end, judges the ungodly, and changes the sun, moon, and stars (15.5).

 

Barnabas moves backward in the list of scriptural citations to take up the significance of sanctifying the Sabbath that was mentioned in 15.1. He allows that if it is possible to sanctify the Sabbath in the present, then he and his audience have been deceived (15.6). However, this is only a rhetorical strategy because Barnabas quickly shifts to the alternative in 15.7. He transitions to his interpretation with another conditional sentence: “But if that is not the case” (εἰ δὲ οὐ). If it is impossible to sanctify the Sabbath properly in the present, Barnabas reasons that it will only be possible to rest and sanctify the Sabbath when believers have been justified (δικαιωθέντες) and received the promise (ἀπολαβόντες τὴν ἐπαγγελίαν). This will be a time when lawlessness no longer exists and when all things have been made new by the Lord. To keep the Sabbath holy requires the Son to make lawlessness utterly ineffectual. Since this has not happened and the letter continues to warn readers against lawlessness, Barnabas continues to look forward to the Sabbath.

 

The author strengthens his argument by appealing to the prophets alongside his interpretations of the Torah. God already told Isaiah that new moons and Sabbaths were unendurable (15.8; Isa 1:13). God’s statement is taken to mean that current Sabbath practices fail to please God, but God can still show favor to the Sabbath that God has made. God’s words continue to be quoted in the first person even though there is no directly comparable scriptural source. When God has set everything at rest on the Sabbath, that is, when the Son returns to bring justice to the world, then God promises to create the start of an eighth day (15.8). The start of this eighth day is then defined as “the beginning of another world” (ἄλλου κόσμου ἀρχήν). The Sabbath is thus interpreted with a view to eschatology and is closely tied to new creation. Barnabas moves from this eschatological interpretation in 15.1–8 to allude to current practices in the community. The reason that Barnabas and his community spend the eighth day joyfully is that it is the day on which Jesus was raised from the dead and ascended into heaven (15.9). The majority of Barnabas’s Sabbath interpretation puts forward an eschatological interpretation of the Sabbath into which the community will be drawn (15.1–8). However, the final verse links the community’s present customs to the discussion to provide further exegetical grounding for differentiating the worship of the true heirs from those who lost the covenant.

 

Barnabas’s reflections on the eschatological Sabbath employ creation themes that were also prominent in the interpretation of Israel’s command to enter the land (6.8–19). In both passages, significant Jewish imagery is taken up and reinterpreted in figurative terms. The land is, among other things, a new creation into which people must enter (6.12–16). The Sabbath is a way of conceptualizing the time when God will set all things right when the Son comes again. Barnabas finds signs in both 6.8–19 and 15.1–9 that the promises from the Torah are yet to be completed. While the Lord tells human beings to rule over the fish (Gen 1:26, 28 [Barn. 6.18]), Barnabas is clear that human beings do not have authority over earthly creatures. Likewise, when Barnabas looks for a holy Sabbath and cannot find one, he reasons that there must be a future Sabbath (Exod 20:8; Deut 5:12, 15 [Barn. 15.1, 6–7]). These signs of incompletion in the Torah lead Barnabas to look for future fulfillment (Barn. 6.13; 15.7). The one who will bring things to fruition is the Son of God. The Son was not only present at creation (6.12) but also resides in believers to bring them before the Father (6.16). Likewise, the Son is the one who will bring the time of the lawless one to no effect and will judge the ungodly (15.5). In describing these actions, Barnabas employs traditional apocalyptic imagery of the sun, moon, and stars being changed. Creation will be altered by the eschatological actions of the Son. By reinterpreting traditional Jewish images, illustrating their incompletion in the present, and looking forward to the Son’s actions in the eschaton, Barnabas provides cohesion to his interpretation of different theological images in the letter.

 

The figurative interpretation of the Sabbath has precedents in Jewish Alexandrian exegetes. Aristobulus interprets God’s rest with reference to God’s continued act of ordering things “for all time” (εἰς πάντα τὸν χρόνον; frag. 5). God gives rest (ἀνάπαυσιν) to human beings on the seventh day, which can be referred to as the first because it is “the beginning of the light in which all things are contemplated” (φωτὸς γένεσις ἐν τὰ πάντα συνθεωρεῖται; frag. 5).313 While Philo links the Sabbath to completion, contemplation, and the perfection of the number seven, he also looks forward to restoration on the Sabbath (Praem. 153). The sense of lack that is suggested in a term like restoration is also found in Barn. 15.6–7. The incomplete nature of Sabbath is critical to understanding the discussion of God’s rest in Heb 3:7–4:11. The Sinai generation failed to enter into God’s rest (Heb 3:11 [Ps 94:11]) or God’s Sabbath (Heb 4:4 [Gen 2:2]) so that there is still a Sabbath remaining for those who are faithful to God (Heb 4:8–10). In different ways, Aristobulus, Philo, and Hebrews link Sabbath to creation and find that Sabbath is a time for completion or restoration. Barnabas likewise emphasizes the link between Sabbath and creation. He shares with Hebrews an open-ended understanding of Sabbath that focuses not on keeping Sabbath in the present but on the eschatological fulfillment of Sabbath.

 

Barnabas’s eschatological interpretation of the Sabbath may be linked to creation, but the interpretation of the days as thousand-year lengths of time has led scholars to ask whether Barnabas was a chiliast. Although other ancient texts also linked Ps 89:4 (90:4) to both the days of creation and to eschatological judgement, early Christian chiliasm refers to “the ancient belief in a thousand-year reign of Christ on earth between his second coming and the last judgment.”318 Irenaeus argues that the resurrection of believers will take place in the flesh and appears to connect the fulfillment of the promise that Abraham’s descendants will inherit the land to the saints’ reign with Christ during the millennium (Haer. 5.30.4–5.32.2). Justin likewise appeals to chiliastic theology (Dial. 80–81). Although Barnabas refers both to a millennial Sabbath and to an eighth day in which all things will be set at rest (Barn. 15.5, 8), his terminology is not consistent. The Sabbath, which is the seventh day, and the eighth day refer to the same eschatological reality in the letter. The author anticipates a time in the future when all things will be put right as the Son judges the lawless one (15.5). Yet this Sabbath judgement is not strongly delineated from the new creation on the eighth day (15.8). Both days look forward to the time of righteousness that is set to follow the Son’s parousia. It is better to regard Barnabas not as a chiliast but instead as someone with a strong hope in new creation after the Son’s return.

 

Eschatological orientations provide a key hinge to the teaching, identity construction, and rationale for acting in the letter. Although Barnabas will emphasize that human beings must act rightly in light of God’s future actions, he emphasizes the incompleteness of the eschaton in 15.1–9. God’s commandment about Sabbath is yet to be completed and, what is more, is impossible to complete at this time. It is not yet possible to keep the Sabbath holy because this is the age of the lawless one. Believers look forward to the completion of the Sabbath when Jesus returns, and Barnabas urges his audience to read scripture rightly by understanding that the Sabbath commandment describes how God’s actions unfold in all of time. For Barnabas, it is important not to reach out and grasp what is still future. This may be one way of conceiving of the error that he finds in Jewish Sabbath practices, namely, that they mistake a future event for present practice. Through believers’ practice of celebrating the eighth day in conjunction with Jesus’s resurrection (15.9), Barnabas’s interpretation of the Sabbath cements his overarching claim that “we” are the true heirs of the covenant and that “we” demonstrate this inheritance by interpreting scripture figuratively and, therefore, rightly.
