“You should seriously consider writing a novel or something.”
Rudolph Otto already did back in 1928, “The Kingdom of God”.
I am sure somebody did. Dan Brown comes to mind as well. The point is, when the disciple who most likely was not at the Last Supper, Cleophas, recognized Jesus in the breaking of the bread despite having talked to Him at some length prior and not recognizing Him, the first thing comes to mind is the Eucharist, and not historical speculations.
