I don't really see the first two things as being specifically spiritual, and I don't see it as much of a stretch to see that they can help with mental well-being. The third one is somewhat recursive, so I obviously can't argue that it isn't specific to gratitude.
The next two definitely feel spiritual, but I feel like they could pretty easily be expressed with "appreciation" and still be spiritual, e.g. "appreciate your blessings" or "appreciate the presence of god".
I'll be honest and say that from my naive understanding of meditation, I don't exactly know how it falls into the "gratitude" bucket. If I were asked to describe what "meditation" is in the spiritual sense, I definitely would have been more like to use the word "appreciation" than "gratitude", e.g. "appreciate one's place in the universe", so I don't really know enough to understand the distinction here.
Overall, to me, this list seems to be a mix of things that are overtly or mostly spiritual and things that don't seem particularly spiritual to me. Maybe it's just my lack of knowledge about this sort of topic, but I'm still not seeing any huge distinction between the two terms based off of those quotes. I definitely agree that from them, the course definitely seems to have a spiritual bent, but the word "gratitude" at least to me doesn't have anything to do with it.
> Where did I write that they are objectionable?
Fair enough; I may have been inferring a tone that wasn't present. It just strikes me as a bit odd that you feel so strongly about the differences between gratitude and appreciation when they don't seem that different to me (and from reading other comments, others seem to share this confusion).
