James White on 3rd Angel's Message SERIES: End Time Inverse Relationship

"Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God and have the testimony of Jesus Christ. God will have His followers united in His worship, and brought into the “unity of the faith,” 

--by keeping the Holy Sabbath; 

--also, the second commandment, in refusing to worship the image of the beast, by not keeping Sunday. 

The opposite will have his followers united, 

--and in unity, in his image worship, by keeping Sunday. 

And he makes war with the remnant for keeping the opposite commandments: the Holy Sabbath and not worshiping an image, in keeping Sunday." James White
