Lutheranism is a major branch of Protestant Christianity that originated with Martin Luther, a 16th-century German monk and theologian. It emerged as a distinct tradition during the Protestant Reformation when Luther challenged certain doctrines and practices of the Roman Catholic Church, posting his famous 95 Theses in 1517. Key aspects of the Lutheran religion include:

• Core Beliefs : Lutherans believe in justification by grace through faith alone (sola fide), salvation solely by God's grace (sola gratia), and that the Bible is the ultimate authority in matters of faith and life (sola scriptura). They affirm the Trinity: God as Father, Son (Jesus Christ), and Holy Spirit.
• Sacraments : Generally, Lutherans recognize two sacraments—Baptism and Holy Communion (Eucharist). They hold to the doctrine of the Real Presence in the Eucharist, meaning Christ is truly present in the bread and wine.
• Worship Style : Lutheran worship retains many elements of the traditional Catholic liturgy but focuses on preaching and Scripture. Pastors can marry, and the authority of the Pope is rejected.
• Historical Roots : Lutheranism grew out of reform efforts in Germany and spread throughout Northern Europe and beyond. It remains one of the largest Protestant denominations with millions of adherents worldwide.
• Theology : Emphasizes salvation as a gift from God, not earned by human works, and upholds the priesthood of all believers.

Lutheranism seeks to balance continuity with the historic Christian church while reforming practices based on Scripture. It has significantly influenced Christian hymnody, education, and social services globally.
