Thirteenth Sunday after Pentecost

Thirteenth Sunday after Pentecost (Proper 16 A)

August 27, 2023

Text: Matt. 16:13-20

            “I believe that I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him.”[1]  Flesh and blood, fallen and bound as it is in sin and death and unbelief, cannot reveal that Jesus Christ is Son of God and Savior.  God must do it.  God must reveal it, and so bring me to this conviction.  The Christian faith is no mere human opinion.  Peter didn’t make it up, nor was he persuaded into the faith by rational argument.  His confession is from God.  The Church’s confession is from God.  When you confess the Creed, and actually believe the words you are speaking, that is God working in you, revealing Jesus Christ, by His Spirit, in His Word.  For flesh and blood has not revealed this to you, but my Father who is in heaven” (Matt. 16:17; ESV).

            How did the Father reveal it to Peter?  Well, Peter witnessed the miracles.  Peter heard the teaching.  Recall, if you will, the miraculous catch of fish, and Peter’s penitential response, “Depart from me, for I am a sinful man, O Lord” (Luke 5:8).  Do not be afraid,” the Lord responded (really a Holy Absolution); for “from now on you will be catching men” (v. 10).  There was the Sermon on the Mount (Matt. 5-7), and the healing of Peter’s mother-in-law, and all those who were sick and afflicted or oppressed by demons (Matt. 8:14-17).  The calming of storms, walking on water, the cleansing of lepers, paralytics taking up their beds and walking, the blind who now see, the deaf who now hear, the dead raised up, and so many poor hearing such good news.  The Word and the Signs.  Peter didn’t know it yet, as he would know it on Pentecost and thereafter, but the Spirit of God was in the Word and the Signs, the Father’s revelation of Jesus the Son.  And Jesus, the Son, revealing His Father as Peter’s Father, the disciples’ Father, our Father who art in heaven, who loves us, and who sent His Son to save us.  The Father reveals the Son.  The Son reveals the Father.  The Spirit proceeds from Father and Son, creating in us new hearts of faith in the Son, who has reconciled us to the Father.    

            Flesh and blood cannot reveal this to us.  The Father reveals Jesus as the Son to us in the same way He revealed Him to Peter.  The Word and the Signs.  For us, it isn’t typically miraculous healings or spectacular displays of the Lord’s authority, like the obedience of wind and waves, or the feeding of the multitudes with five loaves and two fish.  But it is the preaching of this Gospel, the very Words of the Lord Jesus Christ.  And it is the Signs of Baptism and Supper, miracles as profound as any recorded in Holy Scripture. 

            Confession of the Creed… Confession that Jesus is the Christ, the Son of the living God (Matt. 16:16)… flows from this preaching and these Signs.  Confession flows from faith which is born of God in Word and Sacrament.  This is what St. Paul is talking about in Romans 10: “‘The word is near you, in your mouth and in your heart’ (that is, the word of faith that we proclaim); because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.  For with the heart one believes and is justified, and with the mouth one confesses and is saved” (vv. 8-10).  Faith speaks.  Paul is not preaching that the act of confession merits justification or salvation.  Of course not.  But he is simply pointing out the bare fact that faith does not remain silent.  You believe in Jesus Christ, the Son of God, your Savior, and so you confess Him.  And the confession is not something you make up in your own heart.  That would be relying on a revelation from fallen flesh and blood.  No, the confession is what you have been given.  It is joining your voice with that of the holy Christian Church throughout the world, and across the ages, in confessing the Creed.

            “Jesus is Lord” was among the very earliest formulations of the Creed.  It is an echo of Peter’s confession, “You are the Christ, the Son of the living God.”  Really, it was a life and death situation.  Caesar demanded that he be acknowledged and acclaimed as Lord (be warned… given enough time, earthly governments will always make that claim!).  The Christians confessed Another, to whom Caesar himself was accountable.  Arrested, bound, dragged before secular authorities, on pain of death, they were commanded to renounce Christ and burn incense to Caesar.  If they did, they would be released, simple as that.  If they did not… if they persisted in confessing that Jesus is Lord, and Caesar is not, they would face all manner of torture and gruesome death.  There is no question what mere flesh and blood would choose.  But confession is born of the Father’s revelation of the Son by the Spirit.  And so, Paul writes to the Corinthians, “no one speaking in the Spirit of God ever says ‘Jesus is accursed!’ and no one can say ‘Jesus is Lord’ except in the Holy Spirit” (1 Cor. 12:3). 

            It is a life and death situation when you confess the Creed.  The words you now say grew out of the basic confession, “Jesus is Lord.”  The Old Roman Creed, confessed at Baptism, developed into what we know today as “The Apostles’ Creed.”  In the heat of theological controversy, the Church Fathers expanded the articles of the Apostles’ Creed into what we now know as “The Nicene Creed.”  And further controversy gave rise to “The Athanasian Creed.”  Taken together, these three creedal formulas are known as the “Three Ecumenical Creeds,” ecumenical because they confess the faith of all orthodox, biblical Christians.  Ironically, even Christians who claim to profess no formal creeds, by happy inconsistency, do essentially confess these Creeds.  (And, incidentally, everyone has a creed.  “Creed,” from the Latin credo, simply means “I believe,” so if you believe anything, that is your creed.  And if  you don’t believe anything, whatever you may be, you are certainly not a Christian.  Also, let me just say here that it is exceedingly dangerous to despise the three formal Creeds of the holy Christian Church, which are simply a concise summary of Holy Scripture.  It comes perilously close to denying the holy faith delivered to us in the Scriptures, so let’s have none of that talk amongst us!)  So you, whether you are formally speaking the words of the Creed in unison, in united voice, with your fellow Christians, or informally confessing the content of the Creed in your own words to someone who needs to hear about Jesus… flesh and blood has not revealed this to you, but our Father who is in heaven. 

            And this is the rock, this confession, upon which Jesus Christ builds His Church.  And it is against the rock of this confession that the gates of hell will not prevail.  There is a play on words, here, in the Greek, which is not apparent in English Translation.  We know that the name “Peter” means rock.  That is, Πέτρος in Greek, “stone,” perhaps significant and heavy, but something you could pick up with your hands.  (A)nd on this rock I will build my church” (Matt. 16:18).  Now the word for rock is πέτρᾳ in Greek, and that is a boulder big enough to be the cornerstone of the house.  A stone is a chip off the old boulder.  Peter is a rock, sure enough.  But he receives his Christian name (“Stone,” “Rock-man”) in relation to that which was revealed to him by the Father, the rock of his confession upon which Jesus builds His Church.  That confession stops up the gates of hell.  Because that confession… the preaching of Jesus Christ, the Son of the living God… is the Father’s revelation to others that brings them to saving faith in Christ, His Son.  It rescues them from hell, and brings them to eternal life.

            Now, Jesus gives to Peter and the disciples, to His Church, not only the authority to bar the passage to hell, but also to unlock heaven.  That is, He gives the Office of the Keys.  (W)hatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven” (v. 19).  That is, when you forgive the sins of repentant sinners who believe your confession of Jesus Christ, the Son of the living God; and when you withhold forgiveness from the unrepentant as long as they do not repent; this is just as valid and certain, even in heaven, as if Christ, our dear Lord, dealt with them Himself.  Because He has, and He does, through His Church, and through His ministers.  The key of holy Absolution looses sinners from all that binds them to death and hell, and unlocks the door to heaven and eternal life.  Church discipline, on the other hand, binds the sinner in his guilt, and locks the door to life and heaven, until the sinner repents of his sin and is reconciled to God in Christ.  This is the fruit of the Church’s preaching and confession.  On our own, we are damned.  Jesus Christ is the Way to eternal life.  Jesus Christ is the Key to heaven.

            Now, how do you know this?  How do you know the preaching is true?  By the Great Sign… the Sign of Jonah (Matt. 16:4).  For “as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth” (Matt. 12:40).  The Great Sign of Christ, who was crucified, dead, and buried, but who is risen, and lives, is displayed for you in your own watery descent into the abyss with Him, and your coming out again to life and light.  And in His crucified and risen body and blood, given you to eat and to drink, for the forgiveness of your sins.  You hear the preaching.  You see the Signs.  It is the Father bringing you to faith in His Son by His Spirit.  And faith speaks.  You confess.  And blessed are you.  Your confession is the rock.  It is the confession of Peter, and of the Church throughout the ages.  In fact, the Rock is Christ Himself, for He is the whole content of the confession.  He is the Cornerstone (Matt. 21:42) upon which the Church is built.  The apostles and prophets are the foundation (Eph. 2:20).  And you, like living stones, are being built up as a spiritual house, to be a holy priesthood (1 Peter 2:5).  Little Peters.  Stones from the Rock.  The rock is the confession.  The Rock is Christ.  And against that Rock, indeed, the gates of hell can never prevail.  In the Name of the Father, and of the Son X, and of the Holy Spirit.  Amen.
