Where are you getting this little tale from? It sounds like you've been reading Gnostic "Gospels"
I'm not even going to post many verses and the topic involves a lot of verses.
John the Apostle could not have written the Gospel of John as he and two other Apostles saw two events with Jesus and those events are only covered the other three Gospels so that part alone would leave the author unknown even though it is easy to show it was written by a Disciple of John the Baptist that did not become an Apostle like the named one did.
Joh:1:35-40:
Again the next day after John stood,
and two of his disciples;
And looking upon Jesus as he walked,
he saith,
Behold the Lamb of God!
And the two disciples heard him speak,
and they followed Jesus.
Then Jesus turned,
and saw them following,
and saith unto them,
What seek ye?
They said unto him,
Rabbi,
(which is to say,
being interpreted,
Master,)
where dwellest thou?
He saith unto them,
Come and see.
They came and saw where he dwelt,
and abode with him that day:
for it was about the tenth hour.
One of the two which heard John speak,
and followed him,
was Andrew,
Simon Peter's brother.
Joh:21:24:
This is the disciple which testifieth of these things,
and wrote these things:
and we know that his testimony is true.
Joh:21:25:
And there are also many other things which Jesus did,
the which,
if they should be written every one,
I suppose that even the world itself could not contain the books that should be written.
Amen.
The Beloved Disciple is noted as being at the cross when no Apostles were there as they had run away at the arrest. The words said told her to look after his mother and that waqs for life rather than a few days.
Joh:19:26:
When Jesus therefore saw his mother,
and the disciple standing by,
whom he loved,
he saith unto his mother,
Woman,
behold thy son!
Lu:24:10:
It was Mary Magdalene,
and Joanna,
and Mary the mother of James,
and other women that were with them,
which told these things unto the apostles.
This shows that Mary knew all in inner teaching that only the Apostles were taught.
Lu:10:38-42:
Now it came to pass,
as they went,
that he entered into a certain village:
and a certain woman named Martha received him into her house.
And she had a sister called Mary,
which also sat at Jesus' feet,
and heard his word.
But Martha was cumbered about much serving,
and came to him,
and said,
Lord,
dost thou not care that my sister hath left me to serve alone?
bid her therefore that she help me.
And Jesus answered and said unto her,
Martha,
Martha,
thou art careful and troubled about many things:
But one thing is needful:
and Mary hath chosen that good part,
which shall not be taken away from her.
This is a letter from Peter to the Beloved Disciple and it acknowledges that she was with Jesus before he was. The 2nd reference from those 3 epistles mention a woman who is gathering many 'children' to God. 1Jo:1:1-3:
That which was from the beginning,
which we have heard,
which we have seen with our eyes,
which we have looked upon,
and our hands have handled,
of the Word of life;
(For the life was manifested,
and we have seen it,
and bear witness,
and shew unto you that eternal life,
which was with the Father,
and was manifested unto us
That which we have seen and heard declare we unto you,
that ye also may have fellowship with us:
and truly our fellowship is with the Father,
and with his Son Jesus Christ.2Jo:1:1:
The elder unto the elect lady and her children,
whom I love in the truth;
and not I only,
but also all they that have known the truth;
2Jo:1:13:
The children of thy elect sister greet thee.
Amen.
Perhaps you would like to comment on why every reference to 'John' in the Gospel of John is a reference to John thae Baptist.
Elizabeth was a daughter of Aaron, her cousin Mary who became the mother of Jesus is also a daughter of Aaron and they have just about am much authority as a male Priest from the temple. It is quite possible that Mary of Bethany was also a daughter of Aaron.
Joh:11:5:
Now Jesus loved Martha,
and her sister,
and Lazarus.
That should get us started. Since I am correct it would seem that anybody believing otherwise would be guilty of being what you accused me of being, right?
