Doggone it! I don't want to be arguing FOR doulbe whatever, but I don't see evidence on the ground of what you say.
I disagree with those who believe in DP and who claim to possess the "blessed assurance", but I would never describe the ones I know personally as slothful. Manic, yes; untiring busybodies, some of them certainly. But while the RCs are represented way beyond their proportions at our small southern town's ministry to the hungry, them thar Babdisd's are energetically involved.
I know that's not spiritual as such, but it ain't hay either. The Pastor and I used to meet monthly or so for prayer and conversation: no sloth there, not on his part. I personally am VERY slothful, or, as I like to put it, thoughtful and deliberate, just as soon as I get dressed.
Spiritual sloth is inattention to one's own soul. It is quite compatible with being a busybody and attending to other people's souls (in an unhelpful way): as Neko Case laments of her small-town neighbors in one of her songs '. . .mind all of my business, and none of their own. They're all so happy now that I done wrong, I'm surprised they don't come over to thank me.'
