But the seventh day is the sabbath
of the LORD thy God:
Exodus 20:10
CATHOLIC
"Now the Scriptures alone do not contain all the truths which a Christian is bound to believe, nor do they explicitly enjoin all the
duties which he is obliged to practice. Not to mention other examples, is not every Christian obliged to sanctify Sunday and to abstain on that day from unnecessary servile work? Is not the observance of this law among the most prominent of our sacred duties? But you may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday, a day which we never sanctify."
— Faith of Our Fathers, Cardinal Gibbons, p. 72
REFORMED
"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."
--- Westminster Confession of Faith (1646)
7th Day Adventist
"The beneficent Creator, after the six days of Creation, rested on the seventh day and instituted the Sabbath for all people as a memorial of Creation. The fourth commandment of God's unchangeable law requires the observance of this seventh-day Sabbath as the day of rest, worship, and ministry in harmony with the teaching and practice of Jesus, the Lord of the Sabbath. The Sabbath is a day of delightful communion with God and one another. It is a symbol of our redemption in Christ, a sign of our sanctification, a token of our allegiance, and a foretaste of our eternal future in God's kingdom. The Sabbath is God's perpetual sign of His eternal covenant between Him and His people. Joyful observance of this holy time from evening to evening, sunset to sunset, is a celebration of God's creative and redemptive acts."
