Acts 15. Know what "apostolos" really means? "sent". In addition, Jesus sent Paul.
I beg to differ. "Apostolos" does mean "sent," but Messiah specifically chose
twelve whom He named apostles (Lk 6:13) -
not 13 (Rev 21:14).
2 Peter calls Paul's letters "Scriptures", they being along with "the rest of the Scriptures".
It appears you need to study why the Tanach is divided into the Law, Prophets, and Writings, and why the Writings are considered edifying in general, but unproven. If the Apostle Peter wrote 2 Peter, he may have considered Paul's writings to be in the category of the "Writings", as "graphe" in 2Pet 3:16 can be translated merely as "writings".
OK, James is out. Nothing says James is an Apostle. Anywhere. In fact, let's do that to Jude as well. There's even less information there ... So you'll exclude someone Yeshua appears to, resurrected, and appoints to ministry, while including people who have no such claim. ... Poor James. Less and less credibility. James the Less was never said to be appointed an Apostle. Look it up. He's not one of the Twelve.
Messiah appointed both James the Less and Jude to the office of apostle. "Saint James, son of Alphaeus was one of the Twelve Apostles of Jesus Christ. He is often identified with James the Less and commonly known by that name in church tradition" Also, "Jude was one of the Twelve Apostles of Jesus. He is generally identified with Thaddeus" (Wikipedia) ... "
Now the names of the twelve apostles are these ...
James the son
of Alphaeus, and Lebbaeus, whose surname was
Thaddaeus" (Mt 10:2-3), and "of them He chose twelve, whom also He named apostles ...
Judas [the brother] of James" (Lk 6:13,16; also Acts 1:13).
... waiting for you to prove Matthew wrote [his gospel]
The test of an authentic message from Elohim is not mainly the authority of or the identity of the person who communicated it, but
the message itself (Deu 13, Deu 17:6, 19:15, Mt 18:16). The message must be consistent with prior revelation (Isa 8:20), they must point people to YHVH Elohim's Torah and Testimony (Isa 8:19,20), and all prophecies must come to pass (Deu 18:22, Jer 28:9), among other tests. Paul fails all three tests listed. The gospels, including Matthew, and the epistles of James and Jude passes those tests, to my knowledge.
Paul also wrote to Asia Minor churches not to listen to "super-apostles" (check out 1 & 2 Corinthians)
I believe Paul was attempting to lead the congregation away from the true apostles, or what you call the "super apostles" (2Cor 11:5):
1. First, it is Father YHVH's job to give the church-bride to Messiah, not Paul (2Cor 11:2).
2. Second, Paul falsely associates these apostles with the trickery/panourgia of Satan (2Cor 11:3), when he himself states that he used trickery/panourgos to "catch" people with guile/dolos (2Cor 12:16), even as he shows his doublemindedness (cf James 1:8) when he says he never used guile/dolos (1Thes 2:3), cf Eph 4:14, 2Cor 4:2, 1 Pet 2:22.
3. Next, Paul associates these "super apostles" with preaching another gospel and Messiah (2Cor 11:4), yet at the same time he considers himself a part of their group (2Cor 11:5)?!
4. Paul robbed other congregations and took wages from them (2Cor 11:6), Messiah taught that His apostles should not do so (Mt 10:8,9).
5. Paul takes pleasure in his boasting (2Cor 11:10, cf 2Cor 11:17, Rom 5:17, 2Cor 1:12, 7:14, 8:24, 9:4, 1Thes 2:19, etc.) - is this a characteristic of a true apostle? James says such boasting is wicked (Jas 4:16).
6. Paul writes that he is in disagreement with the "super apostles" (2Cor 11:12), but then he calls them false apostles (11:13), and goes on to call them the servants of Satan (11:14-15)! Will you hinge your eternal destiny on the word of one man - Paul - who may have called the true apostles of Messiah the servants of Satan?
7. Paul gives a glimpse at a characteristic of these "super apostles" - they were apparently preaching works of some sort, which Paul rebukes them for (2 Cor 11:15). Perhaps he had in mind the "super apostles" as they were preaching faith & faithfulness (works of Elohim), just as Messiah, James, Peter, and John taught (Mt 5:16, Mk 13:34, Jn 3:21, 6:28,29, 10:37,38, 14:10-12, Jam 1:25, 2:14,17,18,20, 2:21,22,24,25,26, 3:13, 1Pet 1:17,2:12, 1Jo 3:18, Rev 2:2,5, 2:9,19,23,26, 12:17, 20:13, 22:12) - in opposition to Paul's "faith & grace only" message.
8.
Finally, why should we listen to a so-called apostle who admittedly says he is not speaking for Messiah (2Cor 11:17),
but takes confidence in his foolish boasting yet again (2Cor 11:17),
and asks us to tolerate his folly/foolishness (2Cor 11:1),
when Messiah says that foolishness is an evil thing from the heart of man (Mk 7:21-23)
