Article 28

THOSE that have union with Christ, are justified from all their sins by the blood of Christ, which justification is a gracious and full acquittance of a guilty sinner from all sin, by God, through the satisfaction that Christ hath made by His death for all their sins, and this applied (in manifestation of it) through faith.
