Apostle means messenger - there are messengers today:
Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
Eph 4:12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Shalom.
There are no "messengers" as in Apostles in Ephesians 4:11. They died out after John. An office of an Apostle was one who has seen in Person the Resurrected Lord and was appointed by Him.
Luke 1:1-2
Many have undertaken to draw up an account of the things that have been fulfilled among us, 2 just as they were handed down to us by
those who from the first were eyewitnesses and servants of the word.
Acts 5:29-32
Peter and the other apostles replied: "We must obey God rather than men! 30 The God of our fathers
raised Jesus from the dead — whom you had killed by hanging him on a tree. 31 God exalted him to his own right hand as Prince and Savior that he might give repentance and forgiveness of sins to Israel. 32
We are witnesses of these things, and so is the Holy Spirit, whom God has given to those who obey him."
1 Cor 15:3-8
3 For what I received I passed on to you as of first importance : that Christ died for our sins according to the Scriptures, 4 that he was buried, that
he was raised on the third day according to the Scriptures, 5 and that
he appeared to Peter, and then to
the Twelve. 6 After that, he appeared to more than
five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep. 7 Then he appeared
to James, then to
all the apostles, 8
and last of all he appeared to me also, as to one abnormally born.
1 Cor 9:1
Am I not free?
Am I not an apostle? Have I not
seen Jesus our Lord?
Acts 1:22
beginning from John's baptism to the time when Jesus was taken up from us. For one of these
must become a witness with us of his resurrection."
Acts 22:14-15
14 "Then he said: 'The God of our fathers has chosen you to know his will and to see the Righteous One and
to hear words from His mouth.
Acts 22:17-18
17 "When I returned to Jerusalem and was praying at the temple, I fell into a trance 18
and saw the Lord speaking. 'Quick!' he said to me. 'Leave Jerusalem immediately, because they will not accept your testimony about me.'
Acts 22:21
21 "Then
the Lord said to me, 'Go; I will send you far away to the Gentiles.'"
Gal 1:1
Paul,
an apostle — sent not from men nor by man,
but by Jesus Christ
