1. 16:1 A sign from heaven: see note on Mt 12:38–42.
2. 16:2–3 The answer of Jesus in these verses is omitted in many important textual witnesses, and it is very uncertain that it is an original part of this gospel. It resembles Lk 12:54–56 and may have been inserted from there. It rebukes the Pharisees and Sadducees who are able to read indications of coming weather but not the indications of the coming kingdom in the signs that Jesus does offer, his mighty deeds and teaching.
3. 16:4 See notes on Mt 12:39, 40.
4. 16:5–12 Jesus’ warning his disciples against the teaching of the Pharisees and Sadducees comes immediately before his promise to confer on Peter the authority to bind and to loose on earth (Mt 16:19), an authority that will be confirmed in heaven. Such authority most probably has to do, at least in part, with teaching. The rejection of the teaching authority of the Pharisees (see also Mt 12:12–14) prepares for a new one derived from Jesus.
5. 16:6 Leaven: see note on Mt 13:33. Sadducees: Matthew’s Marcan source speaks rather of “the leaven of Herod” (Mk 8:15).
6. 16:7–11 The disciples, men of little faith, misunderstand Jesus’ metaphorical use of leaven, forgetting that, as the feeding of the crowds shows, he is not at a loss to provide them with bread.
7. 16:12 After his rebuke, the disciples understand that by leaven he meant the corrupting influence of the teaching of the Pharisees and Sadducees. The evangelist probably understands this teaching as common to both groups. Since at the time of Jesus’ ministry the two differed widely on points of teaching, e.g., the resurrection of the dead, and at the time of the evangelist the Sadducee party was no longer a force in Judaism, the supposed common teaching fits neither period. The disciples’ eventual understanding of Jesus’ warning contrasts with their continuing obtuseness in the Marcan parallel (Mk 8:14–21).
8. 16:13–20 The Marcan confession of Jesus as Messiah, made by Peter as spokesman for the other disciples (Mk 8:27–29; cf. also Lk 9:18–20), is modified significantly here. The confession is of Jesus both as Messiah and as Son of the living God (Mt 16:16). Jesus’ response, drawn principally from material peculiar to Matthew, attributes the confession to a divine revelation granted to Peter alone (Mt 16:17) and makes him the rock on which Jesus will build his church (Mt 16:18) and the disciple whose authority in the church on earth will be confirmed in heaven, i.e., by God (Mt 16:19).
9. 16:13 Caesarea Philippi: situated about twenty miles north of the Sea of Galilee in the territory ruled by Philip, a son of Herod the Great, tetrarch from 4 B.C. until his death in A.D. 34 (see note on Mt 14:1). He rebuilt the town of Paneas, naming it Caesarea in honor of the emperor, and Philippi (“of Philip”) to distinguish it from the seaport in Samaria that was also called Caesarea. Who do people say that the Son of Man is?: although the question differs from the Marcan parallel (Mk 8:27: “Who…that I am?”), the meaning is the same, for Jesus here refers to himself as the Son of Man (cf. Mt 16:15).
10. 16:14 John the Baptist: see Mt 14:2. Elijah: cf. Mal 3:32–34; Sir 48:10; and see note on Mt 3:4. Jeremiah: an addition of Matthew to the Marcan source.
11. 16:16 The Son of the living God: see Mt 2:15; 3:17. The addition of this exalted title to the Marcan confession eliminates whatever ambiguity was attached to the title Messiah. This, among other things, supports the view proposed by many scholars that Matthew has here combined his source’s confession with a post-resurrectional confession of faith in Jesus as Son of the living God that belonged to the appearance of the risen Jesus to Peter; cf. 1 Cor 15:5; Lk 24:34.
12. 16:17 Flesh and blood: a Semitic expression for human beings, especially in their weakness. Has not revealed this…but my heavenly Father: that Peter’s faith is spoken of as coming not through human means but through a revelation from God is similar to Paul’s description of his recognition of who Jesus was; see Gal 1:15–16, “…when he [God]…was pleased to reveal his Son to me….”
13. 16:18 You are Peter, and upon this rock I will build my church: the Aramaic word kēpā’ meaning rock and transliterated into Greek as Kēphas is the name by which Peter is called in the Pauline letters (1 Cor 1:12; 3:22; 9:5; 15:4; Gal 1:18; 2:9, 11, 14) except in Gal 2:7–8 (“Peter”). It is translated as Petros (“Peter”) in Jn 1:42. The presumed original Aramaic of Jesus’ statement would have been, in English, “You are the Rock (Kēpā’) and upon this rock (kēpā’) I will build my church.” The Greek text probably means the same, for the difference in gender between the masculine noun petros, the disciple’s new name, and the feminine noun petra (rock) may be due simply to the unsuitability of using a feminine noun as the proper name of a male. Although the two words were generally used with slightly different nuances, they were also used interchangeably with the same meaning, “rock.” Church: this word (Greek ekklēsia) occurs in the gospels only here and in Mt 18:17 (twice). There are several possibilities for an Aramaic original. Jesus’ church means the community that he will gather and that, like a building, will have Peter as its solid foundation. That function of Peter consists in his being witness to Jesus as the Messiah, the Son of the living God. The gates of the netherworld shall not prevail against it: the netherworld (Greek Hadēs, the abode of the dead) is conceived of as a walled city whose gates will not close in upon the church of Jesus, i.e., it will not be overcome by the power of death.
14. 16:19 The keys to the kingdom of heaven: the image of the keys is probably drawn from Is 22:15–25 where Eliakim, who succeeds Shebna as master of the palace, is given “the key of the House of David,” which he authoritatively “opens” and “shuts” (Is 22:22). Whatever you bind…loosed in heaven: there are many instances in rabbinic literature of the binding-loosing imagery. Of the several meanings given there to the metaphor, two are of special importance here: the giving of authoritative teaching, and the lifting or imposing of the ban of excommunication. It is disputed whether the image of the keys and that of binding and loosing are different metaphors meaning the same thing. In any case, the promise of the keys is given to Peter alone. In Mt 18:18 all the disciples are given the power of binding and loosing, but the context of that verse suggests that there the power of excommunication alone is intended. That the keys are those to the kingdom of heaven and that Peter’s exercise of authority in the church on earth will be confirmed in heaven show an intimate connection between, but not an identification of, the church and the kingdom of heaven.
15. 16:20 Cf. Mk 8:30. Matthew makes explicit that the prohibition has to do with speaking of Jesus as the Messiah; see note on Mk 8:27–30.
16. 16:21–23 This first prediction of the passion follows Mk 8:31–33 in the main and serves as a corrective to an understanding of Jesus’ messiahship as solely one of glory and triumph. By his addition of from that time on (Mt 16:21) Matthew has emphasized that Jesus’ revelation of his coming suffering and death marks a new phase of the gospel. Neither this nor the two later passion predictions (Mt 17:22–23; 20:17–19) can be taken as sayings that, as they stand, go back to Jesus himself. However, it is probable that he foresaw that his mission would entail suffering and perhaps death, but was confident that he would ultimately be vindicated by God (see Mt 26:29).
17. 16:21 He: the Marcan parallel (Mk 8:31) has “the Son of Man.” Since Matthew has already designated Jesus by that title (Mt 15:13), its omission here is not significant. The Matthean prediction is equally about the sufferings of the Son of Man. Must: this necessity is part of the tradition of all the synoptics; cf. Mk 8:31; Lk 9:21. The elders, the chief priests, and the scribes: see note on Mk 8:31. On the third day: so also Lk 9:22, against the Marcan “after three days” (Mk 8:31). Matthew’s formulation is, in the Greek, almost identical with the pre-Pauline fragment of the kerygma in 1 Cor 15:4 and also with Hos 6:2, which many take to be the Old Testament background to the confession that Jesus was raised on the third day. Josephus uses “after three days” and “on the third day” interchangeably (Antiquities 7:280–81; 8:214, 218) and there is probably no difference in meaning between the two phrases.
18. 16:22–23 Peter’s refusal to accept Jesus’ predicted suffering and death is seen as a satanic attempt to deflect Jesus from his God-appointed course, and the disciple is addressed in terms that recall Jesus’ dismissal of the devil in the temptation account (Mt 4:10: “Get away, Satan!”). Peter’s satanic purpose is emphasized by Matthew’s addition to the Marcan source of the words You are an obstacle to me.
19. 16:24–28 A readiness to follow Jesus even to giving up one’s life for him is the condition for true discipleship; this will be repaid by him at the final judgment.
20. 16:24 Deny himself: to deny someone is to disown him (see Mt 10:33; 26:34–35) and to deny oneself is to disown oneself as the center of one’s existence.
21. 16:25 See notes on Mt 10:38, 39.
22. 16:27 The parousia and final judgment are described in Mt 25:31 in terms almost identical with these.
23. 16:28 Coming in his kingdom: since the kingdom of the Son of Man has been described as “the world” and Jesus’ sovereignty precedes his final coming in glory (Mt 13:38, 41), the coming in this verse is not the parousia as in the preceding but the manifestation of Jesus’ rule after his resurrection; see notes on Mt 13:38, 41.
