John wrote the book of Revelation and to my understanding is the same apostle who wrote the gospel of John
the apostle John was not the author of revelation. and probably not of epistles of john.
he was the author of the gospel of john.
according to modern scholarship and early Christian writings, the other books where written by an unknown author.
John of Patmos - Wikipedia
Authorship of the Johannine works - Wikipedia
all the other apostles died earlier. and did not author any books after the gospel except maybe acts of the apostles.
as for paul. the only person to say Paul is an apostle of Jesus Christ in the entire New Testament is Paul himself.
if that's enough, then you should except also Mohamed, and other false prophets who also said they wrote the words of jesus, and that they where sent by God the father.
this is why Jesus told us to follow only who make genuine true clear supernatural prophesies.
because only God can give a prophecy and make it come true.
this are some examples paul teached directly contrary to God:
1 Timothy 2:8
"I will therefore that men pray every where, lifting up holy hands, without wrath and doubting."
jesus said in Matthew 6:5-8
"
5And when thou prayest, thou shalt not be as the hypocrites
are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.
6But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
7But when ye pray, use not vain repetitions, as the heathen
do: for they think that they shall be heard for their much speaking.
8Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him."
before he said Matthew 6:6
"Take heed that ye do not your righteousness before men, to be seen of them: else ye have no reward with your Father who is in heaven."
also paul said:
"1
It is good for a man not to touch a woman. 2 Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband.."
(catholic priests are celibate all their life because of this)
God(יהוה) said in genesis:
"
20So the man gave names to all the livestock, the birds in the sky and all the wild animals.
But for Adam
f no suitable helper was found.
21So the Lord God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs
g and then closed up the place with flesh.
22Then the Lord God made a woman from the rib
h he had taken out of the man, and he brought her to the man.
23The man said,
“This is now bone of my bones
and flesh of my flesh;
she shall be called ‘woman,’
for she was taken out of man.”
24That is why a man leaves his father and mother and is united to his wife, and they become one flesh."
