When did the Sabbath day change from Saturday to Sunday?

Question

The Sabbath is the 7th day of the week, the day of rest. Why is it celebrated on Sundays, then? I was in church once, and my Sunday school teacher admitted that the Sabbath day was Saturday, but then he went on to say "But wouldn't it be better if we celebrated it on the first day, and not the last?" And I remember thinking, 'Who gave you the right to change that?'
Thoughts, anyone?

Answer 1

Gods people have ALWAYS kept His Seventh day Holy. The Catholics changed the day of worship, and the Protestants have always followed along. The Harlot and her children. The day was changed officially a few years after Constantine's decree (March 7,332 ad.). The Catholic church says that it was she who changed the Sabbath from the 7th day to the 1st.and that if she did not have the power to do so then she could not have done it, and the the Sunday is her Mark (mark of the beast). The sign, seal, mark of God is found in Ex 20:11. Remember that a seal has three parts; the name of the person that holds the office, the title of the office, and the territory. The Lord (name), made (created/creator), the heavens and the earth and all that in them is (territory). So the 4th commandment IS the seal of God. Check out Gen 2:1-3. Adam and Eve kept the first Sabbath with God, this was more then 2500 years before the first Israelite.

Answer 2

The "Sabbath" has never changed. "Sabbath" was the day on which Jews in the Bible (and still today) ake time off from the world to spend with God. It was, and still is, Saturday. Cristians use Sunday as their holy day.

Answer 3

well saturday was originally the seventh day of Genesis which God sanctified and made holy. then when Christ was resurected that was on Sunday so in Judaism it's still Saturday and in Christianity its Sunday
