Lutheranism is a major branch of Western Christianity that identifies with the theology of Martin Luther, a 16th century German reformer. Luther's efforts to reform the theology and practice of the church launched the Protestant Reformation. The reaction of the government and church authorities to the international spread of his writings, beginning with the 95 Theses, divided Western Christianity. The split between the Lutherans and the Roman Catholics arose mainly over the doctrine of Justification. Lutheranism advocates a doctrine of justification "by grace alone through faith alone because of Christ alone" which went against the Roman view of "faith formed by love", or "faith and works". Unlike the Reformed Churches, Lutherans retain many of the liturgical practices and sacramental teachings of the pre-Reformation Church. Lutheran theology significantly differs from Reformed theology in Christology, the purpose of God's Law, divine grace, the concept of "once saved always saved", and predestination.
The key doctrine, or material principle, of Lutheranism is the doctrine of justification. Lutherans believe that humans are saved from their sins by God's grace alone (Sola Gratia), through faith alone (Sola Fide). Lutherans believe that this grace is granted for the sake of Christ's merit alone (Solus Christus). Orthodox Lutheran theology holds that God made the world, including humanity, perfect, holy and sinless. However, Adam and Eve chose to disobey God, trusting in their own strength, knowledge, and wisdom. Consequently, people are saddled with original sin, born sinful and unable to avoid committing sinful acts. For Lutherans, original sin is the "chief sin, a root and fountainhead of all actual sins." Lutherans teach that sinners, while capable of doing works that are outwardly "good," are not capable of doing works that satisfy God's justice. Every human thought and deed is infected with sin and sinful motives. Because of this, all humanity deserves eternal damnation in hell. God in eternity has turned His Fatherly heart to this world and planned for its redemption because he loves all people and does not want anyone to be eternally damned. To this end, "God sent his Son Jesus Christ, our Lord, into the world to redeem and deliver us from the power of the devil, and to bring us to Himself, and to govern us as a King of righteousness, life, and salvation against sin, death, and an evil conscience," as the Large Catechism explains. Because of this, Lutherans teach that salvation is possible only because of the grace of God made manifest in the birth, life, suffering, death, and resurrection, and continuing presence by the power of the Holy Spirit, of Jesus Christ. By God's grace, made known and effective in the person and work of Jesus Christ, a person is forgiven, adopted as a child and heir of God, and given eternal salvation. Christ, because he was entirely obedient to the law with respect to both his human and divine natures, "is a perfect satisfaction and reconciliation of the human race," as the Formula of Concord asserts, and proceeds to summarize: [Christ] submitted to the law for us, bore our sin, and in going to his Father performed complete and perfect obedience for us poor sinners, from his holy birth to his death. Thereby he covered all our disobedience, which is embedded in our nature and in its thoughts, words, and deeds, so that this disobedience is not reckoned to us as condemnation but is pardoned and forgiven by sheer grace, because of Christ alone. Lutherans believe that individuals receive this gift of salvation through faith alone. Saving faith is the knowledge of, acceptance of, and trust in the promise of the Gospel. Even faith itself is seen as a gift of God, created in the hearts of Christians by the work of the Holy Spirit through the Word and Baptism. Faith receives the gift of salvation rather than causes salvation. Thus, Lutherans reject the "decision theology" which is common among modern evangelicals.
Use of the Bible
he Bible (source of doctrine) Traditionally, Lutherans hold the Bible of the Old and New Testaments to be the only divinely inspired book, the only source of divinely revealed knowledge, and the only norm for Christian teaching. Scripture alone is the formal principle of the faith, the final authority for all matters of faith and morals because of its inspiration, authority, clarity, efficacy, and sufficiency. The authority of the Scriptures has been challenged during the history of Lutheranism. Martin Luther taught that the Bible was the written Word of God, and the only reliable guide for faith and practice. He held that every passage of Scripture has one straightforward meaning, the literal sense as interpreted by other Scripture. These teachings were accepted during the orthodox Lutheranism of the 17th century. During the 18th century, Rationalism advocated reason rather than the authority of the Bible as the final source of knowledge, but most of the laity did not accept this Rationalist position. In the nineteenth century, a confessional revival reemphasized the authority of the Bible and agreement with the Lutheran Confessions. Today, Lutherans disagree about the inspiration and authority of the Bible. Theological conservatives use the historical-grammatical method of Biblical interpretation, while theological liberals use the higher critical method. The 2008 U.S. Religious Landscape Survey conducted by the Pew Research Center surveyed 1,926 adults in the United States that self-identified as Lutheran. The study found that 30% believed that the Bible was the Word of God and was to be taken literally word for word. 40% held that the Bible was the Word of God, but was not literally true word for word or were unsure if it was literally true word for word. 23% said the Bible was written by men and not the Word of God. 7% didn't know, weren't sure, or had other positions.
