On October 31, 1517, Martin Luther nailed his now famous 95 Theses to the Castle Church door in Wittenberg. This was a common practice for posting public notices. Luther’s notice was a call for a scholarly debate on the topic of Indulgences. The debate never happened, but Luther’s Theses were published far and wide, sparking the Reformation. Many joined the movement, including important political leaders. Charles V, emperor of the Holy Roman Empire and committed adherent of Rome, summoned an Imperial Diet to meet in Augsburg, Germany. The purpose was to have the princes who had joined the Reformation to confess what they believe, recant of those beliefs, and return to Rome. The princes turned to Philip Melanchthon, Luther’s right-hand man, to draft a document that not only referred to where the Evangelicals differed from Rome, but also where they agreed. He used, of course, source material. That document was submitted June 25, 1530 and was a statement of common Lutheran belief. Because the diet was in Augsburg, the document is called the Augsburg Confession. It has stood the test of time as a clear statement of Lutheran beliefs, and was incorporated into the Book of Concord (1580), which contains all the Lutheran Confessions. The following statements of what we believe, teach, and confess at Lamb of God Lutheran Church are quotes taken from the Augsburg Confession except the last one, which is taken from the Epitome of the Formula of Concord. The translation used is that of F. Bente and W. H. T. Dau You can find the Augsburg Confession and related documents at Project Wittenberg.
Article I – God
Our Churches, with common consent, do teach that the decree of the Council of Nicaea concerning the Unity of the Divine Essence and concerning the Three Persons, is true and to be believed without any doubting; that is to say, there is one Divine Essence which is called and which is God: eternal, without body, without parts, of infinite power, wisdom, and goodness, the Maker and Preserver of all things, visible and invisible; and yet there are three Persons, of the same essence and power, who also are coeternal, the Father the Son, and the Holy Ghost. And the term "person" they use as the Fathers have used it, to signify, not a part or quality in another, but that which subsists of itself. … 
Article II – Original Sin
Also they teach that since the fall of Adam all men begotten in the natural way are born with sin, that is, without the fear of God, without trust in God, and with concupiscence; and that this disease, or vice of origin, is truly sin, even now condemning and bringing eternal death upon those not born again through Baptism and the Holy Ghost. …
Article III – The Son of God
Also they teach that the Word, that is, the Son of God, did assume the human nature in the womb of the blessed Virgin Mary, so that there are two natures, the divine and the human, inseparably enjoined in one Person, one Christ, true God and true man, who was born of the Virgin Mary, truly suffered, was crucified, dead, and buried, that He might reconcile the Father unto us, and be a sacrifice, not only for original guilt, but also for all actual sins of men
He also descended into hell, and truly rose again the third day; afterward He ascended into heaven that He might sit on the right hand of the Father, and forever reign and have dominion over all creatures, and sanctify them that believe in Him, by sending the Holy Ghost into their hearts, to rule, comfort, and quicken them, and to defend them against the devil and the power of sin.The same Christ shall openly come again to judge the quick and the dead, etc., according to the Apostles' Creed.
Article IV - Justification
Also they teach that men cannot be justified before God by their own strength, merits, or works, but are freely justified for Christ's sake, through faith, when they believe that they are received into favor, and that their sins are forgiven for Christ's sake, who, by His death, has made satisfaction for our sins. This faith God imputes for righteousness in His sight. Rom. 3 and 4.
Article V – The Ministry of the Church
That we may obtain this faith, the Ministry of Teaching the Gospel and administering the Sacraments was instituted. For through the Word and Sacraments, as through instruments, the Holy Ghost is given, who works faith; where and when it pleases God, in them that hear the Gospel, to wit, that God, not for our own merits, but for Christ's sake, justifies those who believe that they are received into grace for Christ's sake. …
Article VI – New Obedience
Also they teach that this faith is bound to bring forth good fruits, and that it is necessary to do good works commanded by God, because of God's will, but that we should not rely on those works to merit justification before God. For remission of sins and justification is apprehended by faith, as also the voice of Christ attests: When ye shall have done all these things, say: We are unprofitable servants. Luke 17, 10. The same is also taught by the Fathers. For Ambrose says: It is ordained of God that he who believes in Christ is saved, freely receiving remission of sins, without works, by faith alone.
Article VII – the Church
And to the true unity of the Church it is enough to agree concerning the doctrine of the Gospel and the administration of the Sacraments. Nor is it necessary that human traditions, that is, rites or ceremonies, instituted by men, should be everywhere alike. As Paul says: One faith, one Baptism, one God and Father of all, etc. Eph. 4, 5. 6.
VIII – What the Church Is
Although the Church properly is the congregation of saints and true believers, nevertheless, since in this life many hypocrites and evil persons are mingled therewith, it is lawful to use Sacraments administered by evil men, according to the saying of Christ: The Scribes and the Pharisees sit in Moses' seat, etc. Matt. 23, 2. Both the Sacraments and Word are effectual by reason of the institution and commandment of Christ, notwithstanding they be administered by evil men. …
IX – Baptism
Of Baptism they teach that it is necessary to salvation, and that through Baptism is offered the grace of God, and that children are to be baptized who, being offered to God through Baptism are received into God's grace.
X – The Lord’s Supper
Of the Supper of the Lord they teach that the Body and Blood of Christ are truly present, and are distributed to those who eat the Supper of the Lord …
XI – Confession
Of Confession they teach that Private Absolution ought to be retained in the churches, although in confession an enumeration of all sins is not necessary. For it is impossible according to the Psalm: Who can understand his errors? Ps. 19, 12.
XII – Repentance
Of Repentance they teach that for those who have fallen after Baptism there is remission of sins whenever they are converted and that the Church ought to impart absolution to those thus returning to repentance. Now, repentance consists properly of these two parts: One is contrition, that is, terrors smiting the conscience through the knowledge of sin; the other is faith, which is born of the Gospel, or of absolution, and believes that for Christ's sake, sins are forgiven, comforts the conscience, and delivers it from terrors. Then good works are bound to follow, which are the fruits of repentance. …
XIII – The Use of the Sacraments
Of the Use of the Sacraments they teach that the Sacraments were ordained, not only to be marks of profession among men, but rather to be signs and testimonies of the will of God toward us, instituted to awaken and confirm faith in those who use them. Wherefore we must so use the Sacraments that faith be added to believe the promises which are offered and set forth through the Sacraments. …
XIV – Ecclesiastical Order
Of Ecclesiastical Order they teach that no one should publicly teach in the Church or administer the Sacraments unless he be regularly called.
XV – Ecclesiastical Usages
Nevertheless, concerning such things men are admonished that consciences are not to be burdened, as though such observance was necessary to salvation.
They are admonished also that human traditions instituted to propitiate God, to merit grace, and to make satisfaction for sins, are opposed to the Gospel and the doctrine of faith. Wherefore vows and traditions concerning meats and days, etc., instituted to merit grace and to make satisfaction for sins, are useless and contrary to the Gospel.
XVI – Civil Affairs
Of Civil Affairs they teach that lawful civil ordinances are good works of God, and that it is right for Christians to bear civil office, to sit as judges, to judge matters by the Imperial and other existing laws, to award just punishments, to engage in just wars, to serve as soldiers, to make legal contracts, to hold property, to make oath when required by the magistrates, to marry a wife, to be given in marriage. …
XVII – On Christ’s Return to Judgment
Also they teach that at the Consummation of the World Christ will appear for judgment and will raise up all the dead; He will give to the godly and elect eternal life and everlasting joys, but ungodly men and the devils He will condemn to be tormented without end. …
XVIII – Free Will
Of Free Will they teach that man's will has some liberty to choose civil righteousness, and to work things subject to reason. But it has no power, without the Holy Ghost, to work the righteousness of God, that is, spiritual righteousness; since the natural man receiveth not the things of the Spirit of God, 1 Cor. 2,14; but this righteousness is wrought in the heart when the Holy Ghost is received through the Word. These things are said in as many words by Augustine in his Hypognosticon, Book III: We grant that all men have a free will, free, inasmuch as it has the judgment of reason; not that it is thereby capable, without God, either to begin, or, at least, to complete aught in things pertaining to God, but only in works of this life, whether good or evil. "Good" I call those works which spring from the good in nature, such as, willing to labor in the field, to eat and drink, to have a friend, to clothe oneself, to build a house, to marry a wife, to raise cattle, to learn divers useful arts, or whatsoever good pertains to this life. For all of these things are not without dependence on the providence of God; yea, of Him and through Him they are and have their being. "Evil" I call such works as willing to worship an idol, to commit murder, etc. …
XIX – The Cause of Sin
Of the Cause of Sin they teach that, although God does create and preserve nature, yet the cause of sin is the will of the wicked, that is, of the devil and ungodly men; which will, unaided of God, turns itself from God, as Christ says John 8, 44: When he speaketh a lie, he speaketh of his own.
XX – Faith and Good Works
… our teachers have instructed the churches concerning faith as follows: --
First, that our works cannot reconcile God or merit forgiveness of sins, grace, and justification, but that we obtain this only by faith when we believe that we are received into favor for Christ’s sake, who alone has been set forth the Mediator and Propitiation, 1 Tim. 2, 6, in order that the Father may be reconciled through Him. Whoever, therefore, trusts that by works he merits grace, despises the merit and grace of Christ, and seeks a way to God without Christ, by human strength, although Christ has said of Himself: I am the Way, the Truth, and the Life. John 14, 6.
This doctrine concerning faith is everywhere treated by Paul, Eph. 2, 8: By grace are ye saved through faith; and that not of yourselves; it is the gift of God, not of works, etc. …
Men are also admonished that here the term "faith" does not signify merely the knowledge of the history, such as is in the ungodly and in the devil, but signifies a faith which believes, not merely the history, but also the effect of the history -- namely, this Article: the forgiveness of sins, to wit, that we have grace, righteousness, and forgiveness of sins through Christ. …
Furthermore, it is taught on our part that it is necessary to do good works, not that we should trust to merit grace by them, but because it is the will of God. It is only by faith that forgiveness of sins is apprehended, and that, for nothing. And because through faith the Holy Ghost is received, hearts are renewed and endowed with new affections, so as to be able to bring forth good works. For Ambrose says: Faith is the mother of a good will and right doing. For man's powers without the Holy Ghost are full of ungodly affections, and are too weak to do works which are good in God's sight. …
Hence it may be readily seen that this doctrine is not to be charged with prohibiting good works, but rather the more to be commended, because it shows how we are enabled to do good works. For without faith human nature can in no wise do the works of the First or of the Second Commandment. Without faith it does not call upon God, nor expect anything from God, nor bear the cross, but seeks, and trusts in, man's help. And thus, when there is no faith and trust in God all manner of lusts and human devices rule in the heart. Wherefore Christ said, John 16,6: Without Me ye can do nothing …
XI – The Worship of Saints
Of the Worship of Saints they teach that the memory of saints may be set before us, that we may follow their faith and good works, according to our calling, as the Emperor may follow the example of David in making war to drive away the Turk from his country; For both are kings. But the Scripture teaches not the invocation of saints or to ask help of saints, since it sets before us the one Christ as the Mediator, Propitiation, High Priest, and Intercessor. He is to be prayed to, and has promised that He will hear our prayer; and this worship He approves above all, to wit, that in all afflictions He be called upon, 1 John 2, 1: If any man sin, we have an Advocate with the Father, etc.
Source of Teaching
2. Other writings, however, of ancient or modern teachers, whatever name they bear, must not be regarded as equal to the Holy Scriptures, but all of them together be subjected to them, and should not be received otherwise or further than as witnesses, [which are to show] in what manner after the time of the apostles, and at what places, this [pure] doctrine of the prophets and apostles was preserved.
