(6) Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
(6) Thirdly he shows that they must take heed that the upper part of the building is answerable to the foundation. That is that admonitions, exhortations, and whatever pertains to the edifying of the flock, is answerable to the doctrine of Christ, in the matter as well as in form. This doctrine is compared to gold, silver, and precious stones: of which material Isaiah also and John in the Revelation build the heavenly city. And to these are the opposites, wood, hay, stubble, that is to say, curious and vain questions or decrees: and to be short, all the type of teaching which serves to vain show. For false doctrines, of which he does not speak here, are not correctly said to be built upon this foundation, unless perhaps in show only.
