THIRTEENTH SUNDAY AFTER PENTECOST
Proper 16
(23 August 2026)
Isaiah 51:1–6
Romans 11:33—12:8
Matthew 16:13–20
The Lord Jesus Christ Is the Son of the Living God
Jesus asked His disciples: “But who do you say that I am?” (Matt. 16:15). The question is also put to us: Who do you say that He is? Flesh and blood do not reveal this to us, but by the ministry of the Gospel, the Father in heaven reveals His Son to us on earth, who has become flesh and suffered death for our salvation. Thus, we believe and confess that He is “the Christ, the Son of the living God” (Matt. 16:16). As He died for our transgressions and was raised for our justification, He looses us from all our sins and preserves our life within His Church, against which even “the gates of hell shall not prevail” (Matt. 16:18–19). His salvation is forever, and His righteousness “will never be dismayed” (Is. 51:6). He comforts us with the Gospel in His Church, so that “joy and gladness will be found in her, thanksgiving and the voice of song” (Is. 51:3). Therefore, “according to the measure of faith that God has assigned” (Rom. 12:3), we also offer ourselves “as a living sacrifice, holy and acceptable to God” (Rom. 12:1) through Jesus Christ, our Lord.
Introit (Psalm 2)
P: We will bless the Lord
C: Now and forever, praise the Lord!
P: God says, I put My King
C: On Jerusalem, My holy hill.
P: I will announce this:
C: The Lord told me, “You are My Son. Today I became Your Father.”
P: All nations, praise the Lord!
C: All people, praise Him!
P: His love for us is great.
C: The Lord’s faithfulness continues forever. Praise the Lord!
All: Glory give to the Father and to the Son and to the Holy Spirit, the same as it was in the beginning, is now, and will continue forever. Amen.
Prayer for God’s Word
P: Almighty God, when we know You, that is eternal life. Show us Your Son, Jesus, He is the way, the truth, and the life. Then we can bravely announce He is the Christ. And we can faithfully live the way to eternal life. We pray through Jesus Christ, our Lord. Jesus lives and reigns with the Father and the Holy Spirit, one God, now and forever.
C: (copy) Amen.
What Is a Lutheran?
While there are a variety of ways one could answer this question, one very important answer is simply this, “A Lutheran is a person who believes, teaches and confesses the truths of God’s Word as they are summarized and confessed in the Book of Concord.” The Book of Concord contains the Lutheran confessions of faith.
Perhaps you have attended an ordination of a pastor and heard him promise that he will perform the duties of his office in accord with the Lutheran Confessions. When people are received into membership into a Lutheran congregation through confirmation they are asked if they confess the doctrine of the Evangelical Lutheran Church, as they have learned to know it from the Small Catechism, to be faithful and true.
These solemn promises indicate to us just how important the Lutheran Confessions are for our church. Let’s take a look at the various items contained in the Book of Concord and then we will talk about why the Lutheran Confessions are so important for being a Lutheran.
What are the Ecumenical Creeds?
The three ecumenical creeds in the Book of Concord are the Apostles’ Creed, the Nicene Creed and the Athanasian Creed. They are described as “ecumenical” [universal] because they are accepted by Christians worldwide as correct expressions of what God’s Word teaches.
What is the Augsburg Confession and Apology of the Augsburg Confession?
In the year 1530, the Lutherans were required to present their confession of faith before the emperor in Augsburg, Germany. Philip Melanchthon wrote the Augsburg Confession and it was read before the imperial court on June 30, 1530. One year later, the Lutherans presented their defense of the Augsburg Confession, which is what “apology” here means. It too was written by Philip Melanchthon. The largest document in the Book of Concord, its longest chapter, is devoted to the most important truth of the Christian faith: the doctrine of justification by grace alone, through faith alone, in Christ alone.
What are the Small and Large Catechisms?
Martin Luther realized early on how desperately ignorant the laity and clergy of his day were when it came to even the most basic truths of the Christian faith. Around 1530, he produced two small handbooks to help pastors and the heads of families teach the faith.
The Small Catechism and the Large Catechism are organized around six topics: the Ten Commandments, the Apostles’ Creed, the Lord’s Prayer, Holy Baptism, Confession, and the Sacrament of the Altar. So universally accepted were these magnificent doctrinal summaries by Luther, that they were included as part of the Book of Concord.
What are the Smalcald Articles and the Treatise on the Power and Primacy of the Pope?
In 1537, Martin Luther was asked to prepare a statement of Lutheran belief for use at a church council, if it was called. Luther’s bold and vigorous confession of faith was later incorporated into the Book of Concord. It was presented to a group of Lutheran rulers meeting in the town of Smalcald. Philip Melanchthon was asked to expand on the subject of the Roman pope and did so in his treatise, which also was included in the Book of Concord.
What is the Formula of Concord?
After Luther’s death in 1546, significant controversies broke out in the Lutheran Church. After much debate and struggle, the Formula of Concord in 1577 put an end to these doctrinal controversies and the Lutheran Church was able to move ahead united in what it believed, taught and confessed. In 1580, all the confessional writings mentioned here were gathered into a single volume, the Book of Concord. Concord is a word that means, “harmony.” The Formula of Concord was summarized in a version known as the “Epitome” of the Formula of Concord. This document too is included in the Book of Concord.
What is the connection between the Bible and the Confessions?
We confess that, “The Word of God is and should remain the sole rule and norm of all doctrine” (FC SD, Rule and Norm, 9). What the Bible asserts, God asserts. What the Bible commands, God commands. The authority of the Scriptures is complete, certain and final. The Scriptures are accepted by the Lutheran Confessions as the actual Word of God. The Lutheran Confessions urge us to believe the Scriptures for “they will not lie to you” (LC, V, 76) and cannot be “false and deceitful” (FC SD, VII, 96). The Bible is God’s “pure, infallible, and unalterable Word” (Preface to the BOC).
The Lutheran Confessions are the “basis, rule, and norm indicating how all doctrines should be judged in conformity with the Word of God” (FC SD RN). Because the Confessions are in complete doctrinal agreement with the written Word of God, they serve as the standard in the Lutheran Church to determine what is faithful Biblical teaching, insofar as that teaching is addressed in the Confessions.
Now, may:
The Lord bless you and keep you.
The Lord make His face shine on you and show grace to you.
The Lord look on you and give you peace.
Be safe, keep each other in prayer and, God willing, we will all see each other next Sunday!
