What are the differences between the five main Christian Sabbath keeping groups?

These main groups consist of the Churches of God, Seventh-day Adventist, Church of God (Seventh Day), Seventh Day Baptist, and Messianic Judaism.

When Satan set up his counterfeit religions to lure people away from following God his way, he created religions based on mostly lies mixed with a little truth, and it was very successful, for most of the world has been following after his counterfeit religions, but there has always been those who have refused to be misled by all the lies. Satan being as clever as he is realized that in order to snag those that weren't falling for his lies he would have to do something different, he used mostly truth mixed with a few lies, and again he has been successful.

That is why it is so important to read and study the Bible, so that you can catch the errors being taught before Satan catches you. Always use your Bible to determine whether you are being told the truth when fellowshipping with any of these groups.
