When discussing apostles and prophets, we should always keep this passage before us:
EPHESIANS 2
19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit.
We see here that the Church is depicted as the Building of God -- a Holy Temple, a Habitation of God -- and that the apostles and prophets were foundational -- they laid the foundation of the Church. While the Lord Jesus Christ is the bedrock of that foundation, He is depicted here as the Chief Cornerstone. This immediately tells us that those terms cannot be used loosely. When the New Testament churches were being established then the apostles and prophets were foundational. Today, their writings as found in the Holy Scriptures continue to be foundational.
As to prophets, Scripture clearly tells us that they are distinct from evangelists, pastors, and teachers, since they speak or write by Divine revelation. Which means that their words are the words of God. We do not accept extra-biblical revelations (which have generally been very faulty).
