Lutheranism

Lutheranism is a major branch of Protestant Christianity which identifies with the theology of Martin Luther a German friar, ecclesiastical reformer and theologian.

The key doctrine, or material principle, of Lutheranism is the doctrine of justification. Lutherans believe that humans are saved from their sins by Gods grace alone , through faith alone , on the basis of Scripture alone . 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.
