Benedict and Javl, the SDA’s use the same Bible as everyone else. What makes SDA’s so unique and hard to talk to is the
way that they read the Bible. The way that they approach the Bible is unique among all of the Protestants. Let me put my old SDA hat on and take you on a tour of one belief that shows how this approach works. In brief, the SDA approach is coming to a text with a presupposition, and then going from that assumption to another proof text that looks like it fits and then repeating the process all over again.
So, lets assume you’ve been to a Revelation Seminar (the usual method of evangelizing is by way of a seminar on the prophecies of Daniel and Revelation–which is a perfect place to persuade someone that this method works.) Then you read how E.G. White said that the best diet is a vegetarian one, and you also read that unclean meats are not to be eaten. So, you ask your SDA friend to explain this to you. Here’s about how it would go:
In the beginning, God created man and gave man the diet he was designed for. You can read what that diet is in Gen. 1:29—every herb bearing seed, and every fruit of the trees. So, the original diet was vegetarian and that is what God designed us to eat.
Later, because of sin, God was forced to adapt that command. After the flood, in Gen. 9:3God says
‘Every moving thing that that liveth shall be meat for you; even as the green herb have I given you all things’.
Now be careful here, as God is only talking about all things that are clean. Even in Noahs time, the distinction between clean and unclean was present. Look at Gen. 7:2 in which God commands Noah to take seven of every clean beast; and two of every unclean beast. So, the command that every moving thing shall be meat for you can only apply to the clean beasts.
God made sure that the Isrealites understood this diet by carefully laying out in the law of Moses what to look for in a clean or unclean animal. That is Leviticus, chap. 11 which ends with verse 47 saying:
‘To make a difference between the unclean and the clean, and between the beast that may be eaten, and the beast that may not be eaten’.
This diet is still observed and is part of a prophecy centuries later in Hosea 9:3 which prophesies that
‘Ephraim shall return to Egypt; and they shall eat unclean things in Assyria’.
Some Christians like to say that Jesus said that what you eat can’t defile you. The point to Matt. 15:17 where Christ says that
‘whatsoever entereth in at the mouth goeth into the belly, and is cast out into the sewer’…
But, if you look at v. 20 you can see that the issue is defilement not with food, but by whether you washed your hands or not. As Galatians 4:4 says
‘but when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law’
.
God would not go contrary to His own law and tell someone that you could eat pork or any other unclean food.
Other Christians will refer over to Acts. 10:11-16 where Peter has a vision of a sheet filled with all kinds of creatures, both clean and unclean. Three times Peter is told to kill and eat, three times Peter refused—just as he was supposed to if the dietary law was still in place. In fact, Acts 10:28 tells us exactly what the issue was:
'Ye know how that it is an unlawful thingt for a man that is a Jew to keep company, or come unto one of another nation; but God hath shewed me that I should not call any man common or unclean’.
Now if God had also shown Peter that he could eat anything—why didn’t Peter mention that fact?
And likewise, in 1 Cor. 10:25, when Paul says that you can go to the ‘shambles’ (another word for meat market) and** ‘eat, asking no question for conscience sake’**, you can’t just stop there. 1 Cor. 10:28 tells us what the real issue is
‘But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it’.
Paul is in no way advocating eating clean or unclean meat here.
The issue is clean meats that were being offered to idols!
So, there is no reason for the Christian to be out there eating pork and shrimp and all the other unclean things. There is no difference between a Jewish stomach and that of a Gentile. Got it?
(So, Benedict and Javl, just pass those horrible, grilled pork chops down to me and I’ll take them outside and dispose of them, saving your eternal souls from hell

)
See—that’s how the SDA’s prove things to you. Presuppostion read into proof text after proof text…
