Why pull the thing to pieces looking for a 'meaning'. Barry Gibb as Jesus?? More chance of Ozzie Osbourne as Carmen Miranda
Maybe (considering the time it was written) he was stoned out of his tree!
Can you see any sense in 'Whiter Shade Of Pale' - Even Gary Brooker says he doesn't know what it's about and he wrote it!. He even followed it up with ".....you'd better take off your homburg 'cos your overcoat is" too long.
Back to the Bee Gees - Try "...Now I've found that the world is round and, of course, it rains every day"
I have a lovely vid copy of Lulu and Maurice Gibb (her ex-hubby) doing a live version of '1st Of May'about a year or so before he died - ".... When I was small and Christmas trees were tall..." Brilliant. I loved a lot of their early stuff but Saturday Night Fever (as a soundtrack) was right up there with Cucumber Castle in the 'shite' stakes
