Which day of the seven hath God appointed to be the weekly Sabbath?

Before the resurrection of Christ, God appointed the seventh day of the week to be the weekly Sabbath (Exodus 20:8-11; Deuteronomy 5:12-14); and the first day of the week ever since, to continue to the end of the world, which is the Christian Sabbath (Psalm 118:24; Matthew 28:1; Mark 2:27-28; John 20:19-20,26; Revelation 1:10; Mark 16:2; Luke 24:1,30-36; John 20:1; Acts 1:3; 2:1-2; 20:7; 1 Corinthians 16:1-2).
