243. That there may be a church, there must be doctrine from the Word, since without doctrine the Word is not understood. Doctrine alone, however, does not constitute the church with man, but a life according to it. Hence it follows that faith alone does not constitute the church with man, but the life of faith, which is charity. Genuine doctrine is the doctrine of charity and faith together, and not the doctrine of faith separate from charity; for the doctrine of charity and faith together is the doctrine of life; but not the doctrine of faith without the doctrine of charity.
