Justification by faith alone

The belief that believers are justified, or pardoned for sin, solely on condition of faith in Christ rather than a combination of faith and good works. For Protestants, good works are a necessary consequence rather than cause of justification. However, while justification is by faith alone, there is the position that faith is not nuda fides. John Calvin explained that "it is therefore faith alone which justifies, and yet the faith which justifies is not alone: just as it is the heat alone of the sun which warms the earth, and yet in the sun it is not alone." Lutheran and Reformed Christians differ from Methodists in their understanding of this doctrine.
