My husband's a nominal Christian. He hasn't set foot in a church or opened a bible in the whole time I've known him, except for last Wednesday.
See, he recently got hurt (pulled a muscle in his hip) and scared himself looking stuff up on the Internet about it. He became suddenly and hypochondriacally convinced he had colon or prostate cancer. This is, in part, due to his overall lack of knowledge about how the body works and what kinds of really weird-seeming things are actually normal for the body to do.
He also had his head filled, as a child, with old wives' tales of people getting cancer and dying of it before they even knew they were sick. He'd always thought cancer did that--just snuck up on ya and killed ya <snaps fingers> like
that.
He kept going to the doctor, and being tested, and all tests came out negative. All the doctors
and the nurses there reassured him he didn't have any kind of cancer. None of the tests revealed any abnormal cells of any kind. He did have a mild UTI, which had irritated the prostate, and for which they gave him antibiotics, but no signs of cancer or any serious illness. Yet, he remained unconvinced.
So, Wednesday evening, he rather hesitantly approached me and said he was going to his employer's church (his employer is also a minister), to have them pray over him.
I tried to say nothing, to let him believe whatever he wants to believe, in the same way he does for me and for which I am quite grateful. But he knew it would bug me, so he kept probing for a response. I did finally tell him, under pressure, that I thought he was engaging in magical thinking because he was scared, and that while I understood that, I couldn't agree he was doing the right thing by going for prayer.
"When you find out you're okay--because you
are okay--you won't really know if it's because you've been okay all along, or because God healed you. Can't you wait for your last blood test results to come back first?" I asked.
"Well...this would make me feel better...." he said.
"Okay," I replied, "but let me ask you this: if you are sick, does God know it?"
"Ye-ess..."
"And does he want you to be sick?"
"No...."
"Then why do you have to go to a special building and have a bunch of strangers beg him to make you well again?"
He didn't say anything to that; just walked away deep in thought. That night, he went to the church anyway. He did not feel better about any of it, and his fear remained. Friday, he got his test results: normal. Better than normal, the doctor said. He immediately felt better, and most of his "symptoms" went away immediately.
That's the most discussion we've had about religion in over 10 years. Yeah, it kind of bugs me that he resorted to magical thinking, but I don't think he feels the prayer helped him, so I don't think there's any danger of my having to beat him.

In fact, I think it may have helped him see that magical thinking just doesn't work. I hope so, anyway.
