But that's what Christ was trying to tell us: doing things in the name of God and not in the name of one's hobbies or personal pleasure is not the same. Yet, the Bible is very clear that sabbath is a day of complete rest, even for the live stock.
Shovelling the walk up to church can be done on a Saturday. Again, such planning is in devotion to God, so as not to have to do it on a Sunday. Soup kitchen stuff can be cooked the night before too.
Hmm. What about if it snows Saturday night?
Does the act of serving food to others break any laws of complete rest?
