From my recent posts (here) and (here) discussing the clear distinction between what takes place at the synagogue versus what takes place at the Temple, it has led me to consider the Seventh Day Adventist's claims about the Sabbath. One of the SDA's central accusations is that the Catholic Church allegedly "changed God's day of worship from Saturday to Sunday". But if "worship" wasn't taking place on Saturday (particularly not at the synagogue) then the SDA's entire foundation is obviously deeply problematic.
First, let's consider the Seventh Day Adventist official website's Fundamental Belief #20 "The Sabbath" (here), and the parts which I think need to be highlighted:
The gracious Creator, after the six days of Creation, rested on the seventh day and instituted the Sabbath for all people as a memorial of Creation. The fourth commandment of God’s unchangeable law requires the observance of this seventh-day Sabbath as the day of rest, worship, and ministry in harmony with the teaching and practice of Jesus, the Lord of the Sabbath. (Gen. 2:1-3; Exod. 20:8-11; 31:13-17; Lev. 23:32; Deut. 5:12-15; Isa. 56:5, 6; 58:13, 14; Ezek. 20:12, 20; Matt. 12:1-12; Mark 1:32; Luke 4:16; Heb. 4:1-11.)Notice that throughout their doctrinal explanation the SDAs use the word "worship" with regards to the Sabbath and the 4th Commandment ("Keep the Sabbath"). But what if terminology like "worship" is never to be found in any of these Biblical passages they cite as their primary proof texts, especially the 4th Commandment? That would be deeply embarrassing.
The Sabbath is a day of rest, reflection, enjoyment and worship for God’s people. It dates back to the seventh day of the creation week, when God stopped His work and took time to rest and savor it.
When God rested on the seventh day, He set for us an example. He gave the weekly Sabbath as a day of rest and worship for all of mankind.“He shall speak words against the Most High, and shall wear out the saints of the Most High, and shall think to change the times and the law…” Daniel 7:25
When Jesus lived here on earth He kept the seventh day Sabbath. However, just a few hundred years after His death and resurrection, early Christians began keeping Sunday as their day of worship just as Daniel foretold.
The change of the Sabbath as the day of worship from Saturday to Sunday happened in the year 321 A.D. The Roman Emperor Constantine issued a decree that all Christians were to begin observing Sunday as a day of rest.
[Seventh Day Adventists] decided they would begin to keep the biblical Sabbath even though most churches worshipped on Sunday. Keeping the 4th commandment became a distinctive part of their [SDA] worship.
You can look at all twelve proof texts they have cited above (here). Notice that the language of "rest" and "do no work" appears multiple times. Yet, nowhere does the term "worship" or related language appear in any of these passages. This is kind of a big deal. From the outset, it looks as if the Seventh Day Adventists went around inserting or projecting the idea of "worship" onto the Sabbath day, when in reality the Bible only sees the Sabbath as a time of "resting". How could they make such a blunder?
