The Westminster Shorter Catechism in Question 33 asks “What is justification?”

Answer 33.) Justification is an act of God’s free grace, wherein he pardoneth all our sins,⁽¹⁾ and accepteth us as righteous in his sight,⁽²⁾ only for the righteousness of Christ imputed to us,⁽³⁾ and received by faith alone⁽⁴⁾
