31. Our fathers ate manna in the wilderness. Thus we see that Christ put his finger on the sore, when he told them that they came like brute beasts to fill their belly; for they discover this gross disposition, when they demand a Messiah by whom they are to be fed. And as to the magnificent terms in which they extol the grace of God in the manna, they do this cunningly, in order to bury the doctrine of Christ, by which he condemned them for immoderate desire of corruptible food; for they contrast with it the magnificent title bestowed on the manna, when it is called heavenly bread But when the Holy Spirit bestows on the manna the honorable appellation of the bread of heaven, (Psalms 78:24,) it is not with this intention, as if God fed his people, like a herd of swine, and gave them nothing more valuable; and, therefore, they are without excuse, when they wickedly reject the spiritual food of the soul, which God now offers to them.
