Christian Theology in the context of "Sola fide"

Sola fide, meaning "faith alone," is a Christian doctrine that teaches sinners are forgiven and declared “not guilty” through faith—apart from good works or religious deeds. Protestants traditionally believe that this doctrine of salvation is the cornerstone of Christianity, the very teaching "upon which the church stands or falls".

In classical Protestant theologies, works are the natural evidence of faith, but they do not determine salvation. Confessional Lutheranism sees justification as free forgiveness, received only through faith. Without faith, God's forgiveness is rejected and its benefits are forfeited. Methodism affirms the doctrine of justification by faith alone, but holds that holy living with the goal of Christian perfection (entire sanctification) is essential for salvation; maintenance of sanctification is contingent on continual faith in and obedience to God.
