but i’ve read it also has to do with earthly obligations, just google sloth catholic on google and you’ll see, here on CA it says:
Sloth encompasses all these ideas and more. In his Pocket Catholic Dictionary, the late Jesuit Fr. John Hardon defined sloth as “sluggishness of soul or boredom because of the exertion necessary for the performance of a good work. The good work may be a corporal task, such as walking; or a mental exercise, such as writing; or a spiritual duty, such as prayer.”
hence my doubt, since it seems like even if you have not the obligation to do such good work, it would be sinful to not doing it because you don’t feel like it, because you would not be doing that benefical thing.
