The Westminster Shorter Catechism in Modern English:
Q.24. How is Christ a prophet?
A. As a prophet, Christ reveals the will of God to us for our salvation by His word and Spirit
1. Is Christ called a "prophet" in Scripture and if so, why?
He is called a prophet in Acts 3:22. He is called a prophet because He has made a full revelation of the whole counsel of God.
2. How does Christ reveal to us the will of God?
He reveals God's will to us in two ways: outwardly, by His Word and inwardly, by His Spirit.
3. What is the word of Christ?
The word of Christ is the whole Bible, the Scripture, containing the Old and New Testaments.
4. How can it be that the whole Scripture is the word of Christ since His words constitute only a small portion of it?
The whole Bible is called the word of Christ because those who wrote it wrote the word they had from the Spirit of Christ (1 Peter 1:10-11).
5. Is it possible to be saved simply by means of the Word of God without the Spirit?
No, it is not possible to be saved simply through the Word apart from the Spirit. The teaching concerning this is found in 1 Corinthians 2:14.
6. Is it possible to be saved by the Spirit apart from the Word?
There is a difference here from the previous question in that the Word cannot save you apart from the Spirit and the Spirit will not save you apart from the Word. The Bible teaches that the whole will of God necessary to our salvation is revealed in His Word.
7. How does the Spirit of Christ make us wise unto salvation?
The Spirit of Christ makes us wise unto salvation by opening up our understandings, for the entrance of His word gives us light so that the soul is enabled to see the way of salvation and the way offered.
