The Westminster Shorter Catechism Q59
Which day of the seven hath God appointed to be the weekly Sabbath?
From the beginning of the world to the resurrection of Christ, God appointed the seventh day of the week to be the weekly Sabbath; and the first day of the week ever since, to continue to the end of the world, which is the Christian Sabbath. (Gen. 2:2–3, 1 Cor. 16:1–2, Acts 20:7)
