This is the first sermon in our seven part series on the Synod of Dort's teaching on the Lord's Day.--We begin by comparing what the Heidelberg Catechism and the Westminster Standards teach on the Fourth Commandment.--HEIDELBERG CATECHISM, QUESTION AND ANSWER 103 -1563---103 Q. What is God's will for you in the fourth commandment- -A. First, that the gospel ministry and schools for it be maintained, and that, especially on the festive day of rest, I diligently attend the assembly of God's people to learn what God's Word teaches, to participate in the sacraments, to pray to the Lord publicly, and to bring Christian offerings for the poor. --Second, that every day of my life I rest from my evil ways, let the Lord work in me through his Spirit, and so begin in this life the eternal Sabbath.--Westminster Confession of Faith, 21.7--As it is the law of nature, that, in general, a due proportion of time be set apart for the worship of God- so, in his Word, by a positive, moral, and perpetual commandment binding all men in all ages, he hath particularly appointed one day in seven, for a Sabbath, to be kept holy unto him- which, from the beginning of the world to the resurrection of Christ, was the last day of the week- and, from the resurrection of Christ, was changed into the first day of the week, which, in Scripture, is called the Lord's day, and is to be continued to the end of the world, as the Christian Sabbath.
