When I hear the doorbell at 7am and find a bunch of latter day saints on the door step, I ask “what time is it”?
I get the response, ‘7 am’ and I say..
“Well then...come back latter in the day”! *door slam*
Oh, I no longer get either Mormons or Jehovah’s Witnesses. I think they’ve put a mark on my door or something. The last few times they did come by, I came out on the doorstep and courteously preached Orthodox Christianity to them, pointing out the errors of their respective confessions as I did so.
They went away with the oddest expressions on their faces.
I strongly suggest the method, whatever confession of Christianity (or non-Christian religion) you adhere to: just preach to them when they turn up and after a while, they stop.
