This is.
Revelations 21:14
And the wall of the city had twelve foundations, and on them were the twelve names of the twelve apostles of the Lamb.
Thanks for pointing that out, however, just because that mentions the twelve, it does not mean there are no other apostles.
Case in point: just because someone is called an apostle, does not mean they are the twelve mentioned in Revelation 21:14.
Matthew 10:1And when he had called unto him his twelve disciples, he gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease. [SUP]
2 [/SUP]Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; [SUP]
3 [/SUP]Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus; [SUP]
4 [/SUP]Simon the Canaanite, and
Judas Iscariot, who also betrayed him.
Obviously, Judas Iscariot was replaced as an "apostle".
Acts 1:[SUP]
24 [/SUP]And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen, [SUP]
25 [/SUP]That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place. [SUP]
26 [/SUP]And they gave forth their lots; and the lot fell upon Matthias; and he was numbered with the eleven apostles.
Obviously Matthias is the twelfth apostle for Revelations 21:14
As there are false apostles mentioned by Paul, he did argue the case for his own apostlehsip.
1 Corinthians 1:1Paul called to be an
apostle of Jesus Christ through the will of God, and Sosthenes our brother,
1 Corinthians 9:1Am I am not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord? [SUP]
2 [/SUP]If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord. [SUP]
3 [/SUP]Mine answer to them that do examine me is this, [SUP]
4 [/SUP]Have we not power to eat and to drink? [SUP]
5 [/SUP]Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?
I still can't get the complete definition of apostleship that defers from other offices out of these references either. One who is free? One who has seen the Lord? One who has a following to his ministry? One that has power to eat & drink and to lead others?
Obviously, something defers an apostle from another office.
1 Corinthians 12:[SUP]
28 [/SUP]And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. [SUP]
29 [/SUP]Are all apostles? are all prophets? are all teachers? are all workers of miracles? [SUP]
30 [/SUP]Have all the gifts of healing? do all speak with tongues? do all interpret?
2 Timothy 1:11Whereunto I am appointed a preacher, and an
apostle, and a teacher of the Gentiles.
One could say that it is one that has seen the Lord Jesus Christ but...
Hebrews 3:1Wherefore, holy brethren, partakers of the heavenly calling, consider the
Apostle and High Priest of our profession, Christ Jesus;
I don't think the definition of an Apostle is given to Jesus Christ for seeing Himself in a mirror.
So that is why I doubt anyone knows the actual definition of an apostle. I sure don't.
