To be honest with you I don't have any faith in the epistles/letters written Paul. He was a convert with a convert's zeal not a witness.
If anyone can devine anything from Revelation other than mystic reference that can be moulded into a thousand different meanings be my guest.
The Gospel of John is a different story however your reference is to a wife grieving her husband and a jealous apostle looking for glory.
Mary M. was not the beloved Disciple, Mary the sister of Lazarus was. The children mentioned in connection with her later years are ones she brought into the Church. The Beloved Disciple was not an Apostle, she was A disciple of John the Baptist.
1Jo.1:1:
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;
1Jo.1:2
(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
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;
Joh.1:35:
Again the next day after John stood,
and two of his disciples;
Joh.21:24
This is the disciple which testifieth of these things,
and wrote these things:
and we know that his testimony is true.
Lu.10:42
But one thing is needful:
and Mary hath chosen that good part,
which shall not be taken away from her.
Re.17:7
And the angel said unto me,
Wherefore didst thou marvel?
I will tell thee the mystery of the woman,
and of the beast that carrieth her,
which hath the seven heads and ten horns.
Combine the explanation and add in everything in Daniel about the 4th beast (esp Da.7) and the mysticism is gone. Imiginary names are still used but you would know who is being referenced and that is all we are supposed to know.
