In context we are intended to be reminded of forbidden sexual relations between two men. Luke 17:22-32 is a recounting of the salient points of the Sodom story (Sodom, Lot, fire and brimstone, and Lot's wife). Then comes the reference to "two men in one bed," which refers back to Levitical prohibitions against homosexual relations. "Thou shalt not lie with mankind, as with womankind: it is abomination" (Lev. 18:22).
The story of Sodom is the immediate context of "two men in one bed." In context, we were intended to think of two men in one bed--at night.
When we study the Bible, we're supposed to compare scripture with scripture. In this case, the only O.T. background for two man sleeping in one bed is Leviticus 18:22 and 20:13. And this is precisely what we were intended to think of, with this reference following so closely the Sodom material.
The scribes who worked on one particular manuscript, the Vaticanus Sinaiticus, understood it to be two men, which can be seen in the variant reading they produced: "Two men shall be in one boat."
Men and women did not work together on fishing boats. Fishing was a man's job.
I believe some unknown scribes felt uncomfortable with the implications of "two men in one bed" and changed "bed" to "boat." But this is speculation.
Most scholars I've read agree that verse 34 can be understood either way, as "two people" or "two men." Since verse 35 has "two women," the parallelism that is so typical in Scripture also strongly suggests that we're looking at "two men in one bed."
Also, another unknown scribe introduced verse 36 from Matthew 24, "two men in the field." Why did the scribe borrow this verse and place it here? In order to place all the same-sex couples together in one place.
Please note: everything in these three verses takes place at night. And "in that night" is a very unusual phrase in the scripture.
Luke 17:22-37 forms what I call "Luke's Gay Apocalypse." Luke 17:34-36 forms what I call "The Same-Sex Triptych of Jesus."
Please, let's not get involved in name-calling. Let's study together what this passage actually says, in context, and in the context of its time.
