243. That the Church may exist, there must be doctrine from the Word; because without doctrine the Word cannot be understood. Yet it is not doctrine alone that constitutes the Church with a man, but a life according to doctrine. From this it follows that faith alone does not constitute the Church but the life of faith, which is charity. Genuine doctrine is the doctrine of charity and at the same time of faith, and not the doctrine of faith apart from the former; for the doctrine of charity and at the same time of faith, is the doctrine of life; but not the doctrine of faith apart from the doctrine of charity.
