243. For a church to exist, there must be teaching from the Word, since the Word is not intelligible without teaching. But it is not teaching alone that makes the church in the case of a person, but living in accordance with that teaching. From this it follows that it is not faith alone which makes the church, but the life of faith, which is charity. The true teaching is the teaching of charity and faith together, not faith without charity. For the teaching of charity and faith together is teaching how to live one's life; but the teaching of faith without charity is not.
