Q.61 What is forbidden in the fourth commandment? A. The fourth commandment forbiddeth the omission or careless performance of the duties required, and the profaning the day by idleness, or doing that which is in itself sinful, or by unnecessary thoughts, words, or works, about our worldly employments or recreations. The problem here is that these Sabbath keepers are so busy focusing on keeping the Sabbath day holy that they don't keep the Sabbath. For them, the Sabbath is more like a sacrifice where you give up things. As you can see, these Pharisees completely missed the point!
