Paragraph 22.7
Of the Second London Baptist Confession of Faith
As it is the law of nature, that in general a proportion of time, by God's appointment, be set apart for the worship of God, so by His Word, in a positive moral, and perpetual commandment, binding all men, in all ages, He has particularly appointed one day in seven for a sabbath to be kept holy unto Him,1 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 is called the Lord's Day:2 and is to be continued to the end of the world as the Christian Sabbath, the observation of the last day of the week being abolished.
The Westminster Confession of Faith (1646)
21.7
As it is of 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:1 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,2 which in Scripture is called the Lord's day,3 and is to be continued to the end of the world, as the Christian Sabbath.4
