The article goes on the state:
“WHEN I WAS in college, I remember a lot of projects, papers and assignments were due on Mondays, which made Sunday seem like the natural day to do these.”
“However, I did not feel good about doing these things on Sunday. In fact, I decided that I wouldn’t even do homework on Sunday.”
“For many Christians, Sunday is the Sabbath. It’s a day we dedicate to the Lord. However, how that looks to various denominations and religions is very different.”
“This practice comes from one of the 10 commandments. “Remember the Sabbath day, to keep it holy.” As I understand this, Sunday should be different from the rest of the week. Later in Exodus, we read, “It is a sign between me and the children of Israel forever: for in six days the Lord made heaven and earth, and on the seventh day he rested and was refreshed.”
“Keeping the Sabbath day holy is how we show a sign to God that we respect Him and follow His commandments.”
While this is true, that the Sabbath day is a sign, seal, and stamp of Whom it is we serve, God is specific to which day this is. (hint: it’s not Sunday)
“What might that look like? What sign do we want to give to God on the Lord’s day? I personally try to avoid work including schoolwork. I do my shopping on Saturday so we do not have to go to the store on Sunday.”
“Instead, I focus on spending time with my family. I go to church. I worship God. I partake of the sacrament. I sing hymns. I hear gospel lessons. I read the scriptures.”
“Our Sabbath day doesn’t have to be overly regimented, but I do believe as a society we have strayed from what would be pleasing to God.” 
One word: Antiquity. It seems to “win” again. Since the 4th century and Constantine’s famous Sunday Law on March 7th, 321 AD, most believe Sunday to be the appointed day for the Christian Sabbath. A great span of 1,701 years of history has taken place and settled. Over that time, pagan Rome shifted into papal Rome, true church history has been burned, kept in haughty libraries, and restrained by the enemy of souls.
Yet, has God’s inspired Word ever changed? No.
Does God Himself ever change? No.
Malachi 3:6 KJV “For I am the Lord; I change not;…”
Can God’s ten immutable commandments change?
Of course not. We do not have the power to remove the great lawgiver off of His throne.
Is heaven above us, and the earth beneath?
Luke 16:17 KJV
And it is easier for heaven and earth to pass, than one tittle of the law to fail.
Yet we cannot excuse the fact that some pious, honest in heart men and women of God have believed this buried beneath the mud and “unknown” precept of Jehovah—the seventh day sabbath of the Lord thy God.
The common misconception in this article twist’s Gods word to say that the first day of the week, Sunday, is the sabbath.
Again, where is the testimony in the Scriptures of this enormous change? No where. Where did God set apart, sanctify, and hallow the first day and command it to be kept? No where.
Dear friend, take heart, take comfort, God knew this would happen.
Daniel 7:25 KJV
And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time. (Learn who this “little horn” is here.)
Antiquity amounts to no weight of evidence. Regardless of how old error is, it remains error.
Will you be faithful to God? Will you choose this day to keep all of His commandments? Time is short.
Revelation 14:12 KJV
Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
