I'm experienced enough by now with ATOT and the web in general not to read this entire thread. This reply is to those who care about what God says and wants. Atheists, trolls, humanists, deists, etc- I'm not talking to you.
The Sabbath is the 7th day. God spoke the Ten Commandments with his own voice to the entire assembly of Israel from the top of Mt. Sinai. It's going to take a lot more than some poor interpretation and half-logical gymnastics to change the word of God. If anyone wants to honestly debate the issue from the Bible, or hear what the Bible actually says, let me know.
If nothing else, consider this- the Bible explicitly says what day the Sabbath is, and it says many times to observe it. The Bible says to observe Saturday (Luke 4:16, Exodus 20:8-11). Where does it say to observe Sunday? NOWHERE. Not one single time. Why do people do it? To be brief, sun worship and incorporating pagan customs into what was at that point no longer what Jesus taught anyway, but (and this is an important point) which was still called by his name. Why is that wrong? Deuteronomy 12 is one of the clearest chapters on the subject, though there are many others.
Jesus read, taught, and quoted from the scriptures (Matthew 4). A Christian is one who imitates Christ and his teachings (1John2:6). Therefore, faced with an important question on doctrine, a Christian will not rely on their own judgment or opinions, but diligently search the scriptures to see what God actually says (Acts 17:11). Incorporating pagan rituals into the worship of God is an ABOMINATION (Deuteronomy 12:29-32). Don't believe me, believe God. It's in there, if you want it. There are usually several or many quotes I could list for each one I have put here- none of this is taking single verses out of context, though I am being extremely brief.
To me, the Sabbath issue is one of the best proofs of the existence of Satan, because the Bible is absolutely crystal clear on the subject. But Satan deceives the whole world (Revelation 12:9), which is the only way people could honestly read the Bible in an attempt to obey God and still observe Sunday and not Saturday.
There are answers to all of the vague little "no more Sabbath" passages people twist in an attempt to change their meaning, if anyone wants to understand God rather than justify their own opinions. I'm sure people will respond to this by saying what they think God means, and what customs have changed, and how the church fathers adapted this and that, and how I'm a loser for reading an old book that (so they say) might have been written by man instead of a new book that definitely was written by man, but none of that interests me.
The Bible says observing Saturday as the Sabbath is right. It says observing Sunday as the Sabbath is wrong. Read it for yourself.
?5? ?Then the Pharisees and scribes asked Him, ?Why do Your disciples not walk according to the tradition of the elders, but eat bread with unwashed hands?? 6? He answered and said to them, ?Well did Isaiah prophesy of you ??hypocrites, as it is written:
???This people honors Me with their lips,
But their heart is far from Me.
7 And in vain they worship Me,
Teaching as doctrines the commandments of men.? (Matthew 7:6-7)
