Dude, if you remove the foundation of ANY building, it WILL FALL. Apostles have ALWAYS been on the scene, but just not recognized as such. It is not that the are RE newed....it is that they are now, again, being RECOGNIZED.
Apostles do APOSTOLIC WORK; they found (foundation!) churches and OVERSEE many churches, today, just as in Biblical times.
Prophets STILL hear from God and relay His messages to believers, cities, states, nations. This is called Prophecy and all prophecy today MUST NOT conflict with the written word of God.
Evangelists....Evangelize....their MAIN MISSION is to TELL about CHrist and His Kingdom.
Teachers still TEACH
Pastors Pastor and oversee local groups of people, specific PORTIONS of the Body of Christ.
MISSIONARIES are types of apostles, but few, if any every oversee 50+ churches at one time. They are called missionaires because they GO on a mission...and sometimes it is not that they are 'sent', but just that they WANT to go. This is not the same as being an apostle.
