I think it stems from the false date setting that the bible students and other religious nutters were doing 200 years ago.
Predict a date for Jesus return.... Doesn't happen, so then they just say he did come....... Invisibly.
This was the pattern for 1799, 1874, 1878, 1914, 1925...... The only reason they stuck with 1914 is because when WWI started, they had something significant that year, the other dates just got thrown to the scrap heap.
In conclusion, the 1914/Jesus enthronement is a load of crap.
