I don't know, my mind dosn't want to let this rest. Why couldn't the disciple indicated by the word loved have been a woman? Who knows but the Council didn't change out a few pronouns?
We don't. So I take what's in there as all there is for now.
Now that I think about it, at a gut level, I always had a weird feeling about some other guy leaning on Jesus' bosom (talking since the age of 7 when we first started reading the Gospels in school and going to Mass once a week). It just didn't fit.
And I would NOT look to DaVinci's painting to clarify anything. Besides, I want the Bible to tell me, not a painting from some guy in the 16th century, or any other version. They were not there.
Cool discussion, but that is all for me for now.
