Starting with question 2, the intent is an issue for me. There are plenty of ministers (of all varieties) who have lost their faith, yet continue to serve ‘because it helps the faithful,’ even though they do not believe that this faith is the truth anymore. This is an issue in the ministry - my mom and I have discussed it a few times (she’s a retired UU minister - and yes, faith is an issue in the UU ministry). Do you stay because you are ‘doing some good’ or do you go because you aren’t really THERE anymore? It takes some courage to walk out, but there are some major risks of harm if you stay and pretend - how do you appropriately/effectively counsel someone about god/faith if yours isn’t there? You might miss something important. So, I find staying problemantic, if not strictly immoral. However, if you knew to begin with that what you were preaching wasn’t the truth, and/or you are doing it not to serve but to get some income, community standing, perks, etc., dat’s BAD. (And no fair claiming that you are serving ANYWAY… the primary goal has to be service.)
This is why when I read tarot (yep, I’m one of those weirdos), I do it for free, ALWAYS (and no, I don’t think the cards are magic - but it is a good way of smacking yourself with something you already know but were ignoring!). Heck, I won’t dance for tips, either, because dancing (middle-eastern) is a spiritual practice for me. Money should not be involved. But ministry is a major job, and deserves pay - IF you are there because you have ‘no choice’ but to serve. (In my mom’s Seminary, they asked the students why they wanted to be a minister - all the ones who passed the test said something like, “WANT TO??? You’d have to be NUTS to want this job - I’ve been fighting myself for YEARS, trying to do anything BUT this job, but it keeps dragging me back, kicking and screaming!”) I don’t think you can say you have a true calling if you are lying to make money from anyone, whether they ‘know’ you are a huckster or not.
As for question 1, I don’t really think that the living can contact the dead. HOWEVER, I do not have a problem with the idea that the dead can contact the living, for a purpose, if they care, if the living person is listening, if the living person is, perhaps, ABLE. Every credible instance of such ‘contacts’ that I have heard are ENTIRELY a contact at the discretion of the DEAD person, not the living. If Aunt Josie really wanted/needed to contact YOU, she would have shown up at your bedside the night she died (etc.). Why should she fix YOUR problem if YOU need to see HER??? She’s probably busy. Maybe if you are in a crisis, that might give her reason, but then, it is still up to her whether she shows.
I’ve also encountered a ‘presence’ before (non-dreaming, as far as I can tell - that’s MY perception, though) - pretty stunningly, actually - though that was of a technically LIVING being… a child I was then pregnant with, but subsequently miscarried. (I have a hard time describing that adequately - it certainly changed my perspective, and it was so potent that if I’d been standing, it would have taken me to my knees.) Oh, and I saw my son sitting onteh end of my bed when I was 3 months pregnant - and the vision was accurate, including a hair color that isn’t common in either my genetic family or my husband’s (I described it to other people, and wrote it down, so that’s not just creative remembering).
My other personal contact with the non-living was the series of dreams I had of my three sons (of which I now have one… so far). The dreams happened when I was 7 years old, and I KNEW they were my sons-to-be (which ticked me off, because I at that point thought boys were horrible creatures, even if the sons in my dreams were pretty nice). This kind of event is actually not all that uncommon, though far more common after conception than before. My (living) son has asked me if I remember when he used to play with me in the forest, when he was big and I was a little girl. No, I don’t talk about where we used to play in my dreams - I have always shortened it to ‘we rode bikes and hung out’ when it comes up (which is seldom). Not exactly talking to the dead, but he sure as heck wasn’t ALIVE at the time! I’ve also encountered women who said they were visited by children they had miscarried, though I can easily see that as a creative coping mechanism from the deep subconscious (though I won’t lay odds either way - if your own mind is tricking you, that’s not my problem, and heck, being a spiritual person, maybe it WAS the child). I’ve got enough stories of my son contacting people with IMPORTANT info before he was born or knowing things after he was born to weird-out most people - but again, he was/is technically alive for those.
Count me in the ‘not scientifically proven, certainly not currently provable, not very common, but still quite possible’ camp regarding ‘contact with not-currently-alive persons, by some means, under some conditions, if they feel like it.’ How’s that for a string of dependencies? (Am I the only one, so far? Other than the wife noted in the OP.)
