Faith Alone (Sola Fide)
Justification is by grace alone, through faith alone because of Christ alone. In justification Christ’s righteousness is imputed to us as the only possible satisfaction of God’s perfect justice.
Sola fide and sola gratia express the teaching of Ephesians 2:8:
“For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.”
