The Glory of God Is the Passion and Cross of Christ Jesus
After St. Peter confessed that Jesus is the Christ, the Son of the living God, our Lord “began to show his disciples that he must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and on the third day be raised” (Matt. 16:21). Upon hearing this “theology of the cross,” Simon Peter stumbled into a satanic “theology of glory.” But the glory of God is revealed in the Passion and cross of His incarnate Son. The faithful prophets, such as Jeremiah, suffered persecution and rejection in anticipation of Jesus’ cross. Yet the Lord did not abandon them; He remembered them, and He was with them to deliver them (Jer. 15:15–20). By His cross, Jesus has redeemed the world, and in His resurrection, He has vindicated all who trust in Him. Thus, the Christian life is a discipleship of self-sacrificing love. Since Christ Jesus has reconciled us to God, we “live peaceably with all” (Rom. 12:18). By the certainty of His cross and resurrection, we “rejoice in hope,” and we are “patient in tribulation” and “constant in prayer” (Rom. 12:12).
Introit (Psalm 37)
P: Be happy in the Lord,
C: And He will give you what your heart desires.
P: Trust the Lord with your life.
C: Trust Him, and He will do for you.
P: He will make your righteousness shine.
C: Your right actions will be bright the same-as noon.
P: Have peace, wait patiently for the Lord.
C: Don’t worry about evil people succeeding.
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, Your Son willingly suffered pain and shame on the cross to save us. Make us brave. Then every day we can pick-up our cross and follow Jesus leading. We pray in the name of 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!
