I am trying something new for Sundays. I don't want to talk about what I think that the readings mean, because our priests and pastors and preachers are taking care of that today, so I'm just posting the readings and the footnotes with some links
On the day of 24 August
The feast of Saint Bartholomew, Apostle, who, believed by many to be the same as Nathaniel, sprang from Cana in Galilee, was led to Christ Jesus by Philip near the Jordan, after which the Lord called him to follow him and reckoned him among the Twelve; according to tradition, after the Ascension of the Lord he preached the Gospel in India where he was crowned with martyrdom.
**Saint/Feast of the day segment copied from the USCCB page.
[22] Key: symbol of authority; cf Matthew 16:19; Rev 3:7.
[24-25] If Eliakim should anger God, he and his family (compared here to dishes, bowls and jugs) will suffer disaster
[34] The citation is from the Greek text of Isaiah 40:13. Paul does not explicitly mention Isaiah in this verse, nor Job in 11:35.
[35] Paul quotes from an old Greek version of Jb 41, 3a, which differs from the Hebrew text (Job 41:11a).
[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 the note on Matthew 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 (Mark 8:27: "Who . . . that I am?"), the meaning is the same, for Jesus here refers to himself as the Son of Man (cf Matthew 16:15).
[14] John the Baptist: see Matthew 14:2. Elijah: cf Malachi 3:23-24; Sirach 48:10; and see the note on Matthew 3:4. Jeremiah: an addition of Matthew to the Marcan source.
[16] The Son of the living God: see Matthew 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; Luke 24:34.
[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. . . ."
[18] You are Peter, and upon this rock I will build my church: the Aramaic word kepa - meaning rock and transliterated into Greek as Kephas 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 John 1:42. The presumed original Aramaic of Jesus' statement would have been, in English, "You are the Rock (Kepa) and upon this rock (kepa) 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 ekklesia) occurs in the gospels only here and in Matthew 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 Hades, 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.
[19] The keys to the kingdom of heaven: the image of the keys is probably drawn from Isaiah 22:15-25 where Eliakim, who succeeds Shebnah as master of the palace, is given "the key of the house of David," which he authoritatively "opens" and "shuts" (Isaiah 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 Matthew 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.
[20] Cf Mark 8:30. Matthew makes explicit that the prohibition has to do with speaking of Jesus as the Messiah; see the note on Mark 8:27-30.
