Which day of the week is the Biblical Sabbath day, Saturday or Sunday. ?

Saturday. Sunday is the Lord's Day - the traditional, universal feast day of the Christian Church - quite different in nature and purpose, from the old, Hebrew Sabbath.

Saturday ; but Christians added an other Holy Day , Sunday , and sometimes Wednesday evening .

I think Sunday. Others think Saturday.

The Biblical Sabbath, the Jewish day of worship, has always been on Saturday. The Leaders of the Christian church made Sunday the day of Christian worship because they believed it was more fitting to worship on the day of Jesus Christ's glorious resurrection than on the day He lay dead in the tomb.

That can be understood from Exodus 20:11, with a little research.

Since the Resurrection, we celebrate the Lord's Day, not the Jewish Sabbath.

@ J -- Funny, coming from someone who wouldn't recognize reality after tripping over it.

It doesn't matter as long as you keep it faithfully unto the Lord because the Bible says, "Let no one judge you.......or regarding festivals or a new moon or sabbaths which are a shadow of things to come but the substance is Christ" (Colossians 2:16 & 17) because We are not made for the Sabbath but the other way around, the Sabbath was made for man,(Mark 2:27) and Jesus, the Son of Man is Lord of the Sabbath (Mark 2:28)

Old Testament: Saturday. New Testament:Sunday.

Saturday.  The last day of the week.

But the old traditions are largely ignored by the christians of today.  They are christians in name only, a "real christian" could not survive in a modern world of reality.

Since the BuyBull is clearly a false, nonsense cult book that approves of slavery, rape, beating slaves, misogyny, killing, bigotry, and all kinds of hatred, why on earth would you want to follow ANY of it? Can you even THINK for yourself??
