Kaotic
Again I reiterate
If an apostle means = one who is sent
Because an apostle is called one who is sent doesn't mean that people who are called into ministry are apostles. Christians are called to those offices any more. Part of a good hermeneutic is to look at what other verses have to say about apostles and prophets before you can just say exist today because the word means one who is sent.
Look at the evidence. Sorry for so much emphasis.
Hebrews 1:1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
I said in the OP........
Ephesians 3:5 says that the mystery concerning the church has been revealed to His holy apostles and prophets through the Holy Spirit which indicates that these roles were fulfilled in the first century, and do not continue today.
Ephesians 3:5-6 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
See the word HOLY? That means they are chosen. See how things were not revealed to the sons of men but unto His HOLY apostles and prophets? They were chosen for building and establishing the Church. We are fellowheirs to God's promises. Not prophets.
Ephesians 2:19-20 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
This is what Vine's say's. Emphasis mine.
Apostle, Apostleship:
is, lit., "one sent forth" (apo, "from," stello, "to send"). "The word is used of the Lord Jesus to describe His relation to God,

r 3:1; see Jhn 17:3.
The twelve disciples chosen by the Lord for special training were so called, Luk 6:13; 9:10. Paul, though he had seen the Lord Jesus, 1Cr 9:1; 15:8, had not 'companied with' the Twelve 'all the time' of His earthly ministry, and hence was not eligible for a place among them, according to Peter's description of the necessary qualifications, Act 1:22. Paul was commissioned directly, by the Lord Himself, after His Ascension, to carry the Gospel to the Gentiles.
"The word has also a wider reference. In Act 14:4, 14, it is used of Barnabas as well as of Paul; in Rom 16:7 of Andronicus and Junias. In 2Cr 8:23 (RV, margin) two unnamed brethren are called 'apostles of the churches;' in Phl 2:25 (RV, margin) Epaphroditus is referred to as 'your apostle.' It is used in 1Th 2:6 of Paul, Silas and Timothy, to define their relation to Christ." *

I'm sure there were people who witnessed the ascension or resurrected Christ and were apostles that we aren't aware of.
and...
A prophet = is one who declares the word of God
You have to look at the original text and what other verses say about prophets!
Three words for prophet in the NT.
http://www.eliyah.com/cgi-bin/strongs.cgi?file=greeklexicon&isindex=prophet
This is what Strong's say's,
1) in Greek writings, an interpreter of oracles or of other hidden things
2) one who, moved by the Spirit of God and hence his organ or spokesman, solemnly declares to men what he has received by inspiration, especially concerning future events, and in particular such as relate to the cause and kingdom of God and to human salvation
a) the OT prophets, having foretold the kingdom, deeds and death, of Jesus the Messiah.
of John the Baptist, the herald of Jesus the Messiah
c) of the illustrious prophet, the Jews expected before the advent of the Messiah
d) the Messiah
e) of men filled with the Spirit of God, who by God's authority and command in words of weight pleads the cause of God and urges salvation of men
f) of prophets that appeared in the apostolic age among Christians
1) they are associated with the apostles
2) they discerned and did what is best for the Christian cause, foretelling certain future events. (Acts 11:27)
3) in the religious assemblies of the Christians, they were moved by the Holy Spirit to speak, having power to instruct, comfort, encourage, rebuke, convict, and stimulate, their hearers
3) a poet (because poets were believed to sing under divine inspiration)
a) of Epimenides (Tit. 1:12)

Vines say's.
Prophet:
"one who speaks forth or openly" (see PROPHECY, A), "a proclaimer of a divine message," denoted among the Greeks an interpreter of the oracles of the gods.
In the Sept. it is the translation of the word roeh, "a seer;" 1Sa 9:9, indicating that the "prophet" was one who had immediate intercourse with God. It also translates the word nabhi, meaning "either one in whom the message from God springs forth" or "one to whom anything is secretly communicated." Hence, in general, "the prophet" was one upon whom the Spirit of God rested, Num 11:17-29, one, to whom and through whom God speaks, Num 12:2; Amo 3:7, 8. In the case of the OT prophets their messages were very largely the proclamation of the Divine purposes of salvation and glory to be accomplished in the future; the "prophesying" of the NT "prophets" was both a preaching of the Divine counsels of grace already accomplished and the foretelling of the purposes of God in the future.
If they did end (by whose authority), what then is the purpose to send out missionaries into the world? What does a missionary do? Isn't it to proclaim or declare the Gospel where he was sent to?
Was not Paul commissioned by Jesus to do these very thing and did not Jesus also commissioned His church to go into all the world to preach (declare) the Gospel and make disciples of men?
Paul was a prophet and a messenger. Just because somebody preaches the gospel doesn't qualify them as a prophet. Missionaries are called to be missionaries...not prophets or apostles. Look at the evidence. They were HOLY! They were chosen and called for specif functions in the establishment of the Church.
Not as well as I know how to study it.
