In no other way can the two classes of worshipers be distinguished.

From this conclusion, no candid mind can dissent; but in this conclusion we have a general answer to the question before us, "What constitutes the mark of the beast ?" THE MARK OF THE BEAST is THE CHANGE HE HAS MADE IN THE LAW OF GOD.
We now inquire what that change is.

By the law of God, we mean the moral law, the only law in the universe of immutable and perpetual obligation, the law of which Webster says, defining the terms according to the sense in which they are almost universally used in Christendom, "The moral law is summarily contained in the decalogue, written by the finger of God on two tables of stone, and delivered to Moses on Mount Sinai." If, now, the reader will compare the ten commandments as found in Roman Catholic catechisms with those commandments as found in the Bible, he will see in the catechisms that the second commandment is left out, that the tenth is divided into two commandments to make up the lack of leaving out the second, and keep good the number ten, and that the fourth commandment (called the third in their enumeration) is made to enjoin the observance of Sunday as the Sabbath, and prescribe that the day shall be spent in hearing mass devoutly, attending vespers, and reading moral and pious books.

Here are several variations from the decalogue as found in the Bible.

Which of them constitutes the change of the law intended in the prophecy?
or, are they all included in that change?
Let it be borne in mind that, according to the prophecy, he was to _think_ to change times and laws.
