You asked me that same question almost three years ago. I came up with this:Are you aware of any ancient, or even greater then 100 years old, source material describing this? I've looked for years but not found anything. Can you point me in a direction?
Much love!

Ancient sources? Don't know of any. I did first hear about it from Dr..Craig Johnson, my first pastor/ professor long ago.
All the disciples were Galileans except Judas, so they would be aware of symbolism Jesus used to allude to the wedding. It was a theme that ran through the Bible: The Church being the bride, the betrothal made, a covenant, a commitment, preparations, "I go and prepare a place for you and I will return", " No one knows the day or the hour ... only the Father", His Father's tells Him when it is time to go get His bride and the trumpet is blown, the bride is ready, the wedding party has oil in there lamps, he lifts her up and carries her away to the Father's house and the door is shut.
Sounds true. If you could find those old books in a Library, check the references and sources in those books.
