“I gave them my sabbaths, to be a sign between me and them, that they might know that I am the Lord that sanctify them” (Ezekiel 20:12). “It is a sign between me and the children of Israel for ever: for in six days the Lord made heaven and earth” (Exodus 31:17).
God gave us His Sabbath as a glorious sign of His power to create and His power to sanctify (convert and save) us. In the Bible, the words seal, sign, mark, and token are used interchangeably (Compare Genesis 17:11 with Romans 4:11 and Revelation 7:3 with Ezekiel 9:4).
Revelation 7:1-3 says His mark will be written upon the foreheads (minds, Hebrews 10:16) of His people. It will signify that they are owned by Him and have His character. Hebrews 4:4-10 confirms this by saying that when we enter His rest (receive salvation), we should keep His seventh-day Sabbath holy as a symbol, or mark, of salvation. True Sabbath-keeping signifies that a person has surrendered his life to Jesus Christ as Savior and Creator.
Since the symbol, or mark, of God’s authority and power is His holy seventh day Sabbath, it seems likely that the symbol, or mark, of God’s opposer, the “beast,” might also involve a holy day. Notice the following section from a Catholic catechism:
“Question: Have you any other way of proving that the Church has power to institute festivals of precept?”
“Answer: Had she not such power, she could not have done that in which all modern religionists agree with her – she could not have substituted the observance of Sunday the first day of the week, for the observance of Saturday the seventh day, a change for which there is no Scriptural authority.” Stephen Keenan, A Doctrinal Catechism [FRS No. 7.], (3rd American ed., rev.: New York, Edward Dunigan & Bro., 1876), p. 174.
The papacy is here saying that it changed the observance of the seventh day Sabbath to Sunday. Thus, the papacy claims that Sunday as a holy day is the mark, or symbol, of her power and authority.
