To 'justify' means nothing else than to acquit of guilt him (her) who was accused as if his own innocence were confirmed.
John CalvinWhensoever God's truth is defaced or when any man turns away from the pure simplicity of the Gospel, we must not in any wise spare him, but although the whole world should set itself against us, yet must we maintain the case with invincible constancy, without bending for any creature.
John CalvinUnless men establish their complete happiness in God, they will never give themselves truly and sincerely to him.
