Why not go all the way and replace Christ with the fisher-king myth?
Because I don't know if it is true or not. I do know that household gods played an important role in pagan Rome and I have personally seen saints used in exactly the same way by Roman Catholics. My father-in-law misplaced his wallet and my Mother-in-law prayed to Saint Anthony of Padua, the "patron saint of lost items" and shazzam! the next time she came up the stairs, she saw the wallet under the bed!. This attribution of a specific sphere of influence for a lessor god is typical of paganism. Hindus pray to Ganesh (the one that Homer Simpson gave a peanut to) for success in business, for example.
Who cares what Protestants believe? If they do not want a relationship with the Elect, that’s their call.
