I knew that Jesus had sometimes upset people by His behavior on the Sabbath. He did attend synagogue, but He also did things which bothered the Jewish religious leaders, like healing people on the Sabbath, or allowing His disciples to grab a snack from the surrounding fields on the Sabbath [a practice which was perfectly acceptable, by the way, as long as you didn't go over the line and take a large quantity, which would have been considered to be harvesting someone else's field and thus, stealing.] Jesus was grieved by the lack of love or concern for other humans which these religious leaders demonstrated when they questioned his healing of a man on the Sabbath, especially since these same leaders would have seen no problem with their own actions of feeding or helping one of their own animals if they were hungry or distressed on a Sabbath. Yet apparently these religious leaders could not extend the same concern toward a fellow man. This grieved Jesus, who went ahead and healed the guy anyway despite their objections.
This discussion is not over, but I will move on for now. If I find any interesting thoughts on the subject of this commandment, I will add them here.
OK, I already found an interesting verse: Colossians 2:16-18 says "Therefore, do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration, or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ."
