Question 115: Which is the fourth commandment?

Answer: The fourth commandment is, Remember the sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work: but the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.

Question 116: What is required in the fourth commandment?

Answer: The fourth commandment requires of all men the sanctifying or keeping holy to God such set times as he has appointed in his Word, expressly one whole day in seven; which was the seventh from the beginning of the world to the resurrection of Christ, and the first day of the week ever since, and so to continue to the end of the world; which is the Christian sabbath, and in the New Testament called the Lord's day.

Question 117: How is the sabbath or the Lord's day to be sanctified?

Answer: The sabbath or Lord's day is to be sanctified by an holy resting all the day, not only from such works as are at all times sinful, but even from such worldly employments and recreations as are on other days lawful; and making it our delight to spend the whole time (except so much of it as is to betaken up in works of necessity and mercy) in the public and private exercises of God's worship: and, to that end, we are to prepare our hearts, and with such foresight, diligence, and moderation, to dispose and seasonably dispatch our worldly business, that we may be the more free and fit for the duties of that day.

Question 118: Why is the charge of keeping the sabbath more specially directed to governors of families, and other superiors?

Answer: The charge of keeping the sabbath is more specially directed to governors of families, and other superiors, because they are bound not only to keep it themselves, but to see that it be observed by all those that are under their charge; and because they are prone ofttimes to hinder them by employments of their own.

Question 119: What are the sins forbidden in the fourth commandment?

Answer: The sins forbidden in the fourth commandment are, all omissions of the duties required, all careless, negligent, and unprofitable performing of them, and being weary of them; all profaning the day by idleness, and doing that which is in itself sinful; and by all needless works, words, and thoughts, about our worldly employments and recreations.

Question 120: What are the reasons annexed to the fourth commandment, the more to enforce it?

Answer: The reasons annexed to the fourth commandment, the more to enforce it, are taken from the equity of it, God allowing us six days of seven for our own affairs, and reserving but one for himself, in these words, Six days shalt thou labor, and do all thy work: from God's challenging a special propriety in that day, The seventh day is the sabbath of the Lord thy God: from the example of God, who in six days made heaven and earth, the sea, and all that in them is, and rested the seventh day: and from that blessing which God put upon that day, not only in sanctifying it to be a day for his service, but in ordaining it to be a means of blessing to us in our sanctifying it;Wherefore the Lord blessed the sabbath day, and hallowed it.

Question 121: Why is the word Remember set in the beginning of the fourth commandment?

Answer: The word Remember is set in the beginning of the fourth commandment, partly, because of the great benefit of remembering it, we being thereby helped in our preparation to keep it, and, in keeping it, better to keep all the rest of the commandments, and to continue a thankful remembrance of the two great benefits of creation and redemption, which contain a short abridgment of religion; and partly, because we are very ready to forget it, for that there is less light of nature for it, and yet it restrains our natural liberty in things at other times lawful; that it comes but once in seven days, and many worldly businesses come between, and too often take off our minds from thinking of it, either to prepare for it, or to sanctify it;and that Satan with his instruments much labor to blot out the glory, and even the memory of it, to bring in all irreligion and impiety.

If you want to start an argument in my denomination you can always bring up the Sabbath, and what is or is not permitted on it. Can you go out for lunch after church? One guy I heard say that going out to eat after church is like "plundering the Egyptians." Whether it's permissible or not, one has to admit, I think, that exchanging money for goods is a very strange sort of plundering. You give me money, and I give you food. I'm not sure how I'm being plundered.

Whatever. What concerns me is the catechism's teaching, here that, among other things it should be "our delight to spend the whole [day] in the public and private exercises of God's worship". This part of the catechism always makes me wonder: If I were as punctilious in my observance of the Fourth Commandment as I am in that of, say, the Seventh, what would my Sundays look like? Hhhmmm.

Fortunately, I have plenty of friends who care enough to "free" me from my "legalism".
