"This, however, remains certain: the perfect doctrine he has brought has made an end to all prophecies. All those, then, who, not content with the gospel, patch it with something extraneous to it, detract from Christ's authority. The Voice that thundered from heaven, 'This is my beloved Son; ... hear him' (Matt. 17:5; cf. Matt. 3:17), exalted him by a singular privilege beyond the rank of all others. Then this anointing was diffused from the Head to the members, as Joel had foretold: 'Your sons shall prophesy and your daughters ... shall see visions,' etc. (Joel 2:28). But when Paul says that He was given to us as our wisdom (I Cor. 1:30), and in another place, 'In him are hid all the treasures of knowledge and understanding' (Col. 2:3), he has a slightly different meaning. That is, outside Christ there is nothing worth knowing, and all who by faith perceive what he is like have grasped the whole immensity of heavenly benefits. For this reason, Paul writes in another passage: 'I decided to know nothing precious ... except Jesus Christ and him crucified' (I Cor. 2:2). This is very true, because it is not lawful to go beyond the simplicity of the gospel And the prophetic dignity in Christ leads us to know that in the sum of doctrine as he has given it to us all parts of perfect wisdom are contained"
