Q. 59 Which day of the seven hath God appointed to be the weekly Sabbath? A. 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. So you see that this is simply telling us that after Jesus was resurrected, God changed the weekly Sabbath from Saturday to Sunday. This is not as simple of a subject… you will need to follow along in your Bibles.
