Hey Jude was originally "Hey Jules", McCartney's nick for John's son Julian. At the time the Lennons were going thru a divorce, & Paul intended the song to be a small consolation to his "nephew". He changed the name to avoid offending John, & most of the other words were simply filler until something better came along (a common practice of Paul's; "Yesterday" was famously given the working title of "Scrambled Eggs" until he could come up with lyrics that didn't make people think, "WTF?") In the event, Paul played his 1st draft for John, apologizing that he would come up with better words later. John vetoed the idea, claiming he understood exactly what "the movement you need is on your shoulder" meant. That was pretty much the extent of John's contribution, giving the stamp of approval to the song as finished.

In a way, I guess you could say it matched up as a statement by John, even though he didn't write a single word of it. I doubt he knew or cared what St Jude stood for...in fact, he later claimed to believe that it was his name that Paul had substituted, as if giving a subconscious blessing to John's quest for a new life outside of the Beatles.
