The much-quoted and read “Lord’s Day” is associated with Sunday and is one of the Roman Catholic Church’s extensive deceptions. According to the Gospel, this day has nothing to do with Sunday. The Bible provides unmistakable and clear information here.

Exclusive definition of the Church of Rome

One of the numerous consciously generated misunderstandings of the Gospel is the everyday term “Lord’s Day”. This of course means Sunday today. On this special day, all Catholic and Protestant believers should come to church service. But a look at the Bible shows a completely different meaning for the “Lord’s Day”. The determination of the “Lord’s Day” as a “sanctuary Sunday” is once again one of the countless confusions played by the Church of Rome.
Detailed evidence, some from ancient sources, about the early Church of Rome’s own life in relation to the pagan sun cult can be read here.
The Bible about the “Day of the Lord”
The Bible only provides information in one place in which the “Lord’s Day” also refers to a specific day of the week. This is the case in Isaiah 58:13. However, it is not the Sunday (“Sun Day”) propagated by the Catholic and Protestant churches, but rather the Sabbath. So the 7th day of the week and according to our calendar that is Saturday.

This verse in Isaiah is apparently proving uncomfortable for the churches. This applies to the Catholic Church as well as to the former Protestant houses (Info). In some new editions of the Bible, this verse has now been reworded in such a way that the reference “Lord’s Day” to the Sabbath is no longer apparent (Info).
The original textus receptus Bibles
In the Bible translations, which are based on the textus receptus, the “Day of the Lord” is in Isaiah 58:13 still clearly in the context of the Sabbath.
Schlachter 2000 (German bible)
If you hold back your foot on the Sabbath, from doing what pleases you on my holy day; if you call the Sabbath your delight, and the holy [day] of the Lord honorable; if you honor him, so that you do not go about your business, nor minister your business, nor speak idle words;
In contrast to Luther 1912, the Luther 2017 is already based on the “scientific” Nestle-Aland basic text, but here the Sabbath is still clearly connected to the “Day of the Lord”.
If you turn back your foot on the Sabbath, and do not go about your business on my holy day, and call the Sabbath delight, and the Lord’s holy day Honored; if you honor him by not going about your walks and not conducting your business and talking idle chatter,
Another textus receputs variant is the German Elberfelder. “The day of the Lord” here also refers to the Sabbath.
If you keep your foot from the sabbath from conducting your business on my holy day, and call the sabbath a delight and the holy ⟨day⟩ of the LORD honorable, and ⟨if you⟩ honor it, so that you do not go about your walks, your business follow and speak ⟨vain⟩ words
The English King James Version is based on textus receptus and therefore also correctly linked the “Lord’s Day” to the Sabbath.
If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
More modern Nestle-Aland Bibles
The following Bible editions each use the Nestle-Aland basic text. Although there is talk of a Sabbath, the connection to the “Lord’s Day” no longer exists.
Einheitsübersetzung 2016 (“Unit Translation 2016”)
If you hold back your foot on the sabbath, / to do your business on my holy day, if you call the sabbath a delight, / holy to the LORD, most honored, if you honor him without walking / and without dedicating yourself to business and to say many words
Gute Nachrichten 2018 (“Good news 2018”)
The LORD says: ‘Respect the Sabbath as a holy day, which is mine. Do not dishonor him by pursuing your occupations. Don’t profane him by traveling or by work or any business. Do not regard it as a burden, but as an occasion for joy!
Hoffnung für Alle (“Hope for all”)
Respect the Sabbath as a day dedicated to me and on which you do not transact business! Let it be a holiday for you to look forward to. Don’t profane him by your work, business, or idle chatter! Rather, respect it as a day that belongs to me, the LORD.
“Day of the Lord” – Judgment Day
The “Lord’s Day” in connection with the Sabbath is an exception even in the Bible. Nevertheless, the term “Lord’s Day” occurs very frequently in Holy Scripture and all statements have in common that the “Lord’s Day” does not describe a day of the week, let alone Sunday, but the so-called Last Day. The day when the Lord Jesus Christ returns, along with the consequences that come with it. “The Day of the Lord” is by no means Sunday, but rather the day of Jesus’ return!

Early forgery “Day of the Lord” on Sunday

You can see it clearly: The reference of the “Lord’s Day” to Sunday is due to the usual individual life of the Roman Catholic Church. Unfortunately, this interpretation has also been adopted by the once Protestant churches.
Ignatius of Antioch
The Roman Catholic Church made this “miraculous transformation” of the “Day of the Lord” very early in its history. The Bishop of Antioch, Ignatius of Antioch, spoke in one of his letters of the “Lord’s Day” in connection with the solar day (Sunday). The lifespan of Ignatius is not entirely clear. While some scientists date his work around 110 AD, others place him around 160 AD. Today Ignatius is venerated as a “saint” by both the Roman and Orthodox Catholic Churches.
The “Holy Martyr Justin”
Another early “Church Father” was the “Holy Martyr Justin” (AD 110-165). In his work “First Apology” he wrote in chapter 67:
“And afterwards we continually remind each other of these things. And the wealthy among us help the needy; and we always keep together; and for all things with which we are supplied, we bless the Maker of all through His Son Jesus Christ, and through the Holy Ghost. And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we said before, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows and those who, through sickness or any other cause, are in want, and those who are in bonds and the strangers sojourning among us, and in a word takes care of all who are in need. But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, made the world; and Jesus Christ our Savior on the same day rose from the dead. For He was crucified on the day before that of Saturn (Saturday); and on the day after that of Saturn, which is the day of the Sun, having appeared to His apostles and disciples, He taught them these things, which we have submitted to you also for your consideration.“
The next deception soon followed

Based on what the Bible says, you can see that the “Day of the Lord” actually describes the Last Day or the return of Jesus Christ. The Church of Rome redefined the “Lord’s Day” as the first day of the week, the “Sun Day” in honor of their secretly worshiped “Sun God”. This was manifested by Emperor Constantine through his decree on Sunday sanctification in 321.
The Sabbath (7th day of the week), which is strongly emphasized in the Bible, was simply moved to Sunday by the Church of Rome as a “holy day”.
Since then, Sunday has been considered “Lord’s Day” (1st day of the week, Sunday), on which church services should also be held. The Sabbath prescribed by the Bible, i.e. the 7th day of the week (Saturday), was simply declared a “Jewish holiday”. Christians were forbidden, even under threat of sanctions, from keeping the biblical Sabbath. It is the Church of Rome itself that recognizes the true Sabbath as fully biblical, but simply ignores this and elevates its own catechism over the Gospel (Info).
To add to the deliberate confusion surrounding “Lord’s Day”, “Sunday” and “Sabbath”, Sunday has recently been referred to as the “Sabbath”. However, you can read here how the (real) Sabbath to be observed is actually ordered and to whom it applies.
Summary:
-
The biblical “Day of the Lord” refers almost exclusively to the time of Jesus Christ’s return, i.e. the so-called Judgment Day. With only one exception, the “Day of the Lord” refers to the Sabbath.
-
The biblical “Day of the Lord” never refers to Sunday in the Bible
-
The Biblical Sabbath is the 7th day of the week (Saturday)
-
Nowhere in the Bible is the sanctification of Sunday (1st day) prescribed, but the Sabbath (Saturday, 7th day) is still binding.
