Papacy Boasts of Calendar Change

The Catholic Church has always been very open about her role in changing the calendar.  Modern sabbatarians have assumed that Saturday was the Bible Sabbath, but the Catholic Church herself has never denied the role she played in rejecting the luni-solar Sabbath of the Bible and promoting instead worship on dies Solis, the day of the Sun.

The decision of the Council of Nicaea to set aside Biblical calendation was merely confirmed by Constantine in royal edict.  The bishops wanted to destroy any ties to Judaism.  Anti-semitism played a role, as can be seen in the previously quoted statement by Constantine: “Let us have nothing in common with this odious people [the Jews] . . . .” (1)

Patrick Madrid, in a radio interview on January 5, 2006, made a point of this: 

There was a distinct break between the Old Testament requirements: the rituals and Mosaic covenant demands dealing with the Sabbath worship and animal sacrifices, and that sort of thing.  And they wanted to show that Christianity was distinct from Judaism.  It came from Judaism, but it was distinct from it. (2)

In endeavoring to show this distinction, not only was the observance of the seventh-day Sabbath transferred to the Julian Sunday, but all of the annual feasts which, up until that time were still observed, were replaced with popular pagan festivals, giving them a Christian slant and incorporating Christian names. 

To conciliate the Pagans to nominal Christianity, Rome, pursuing its usual policy, took measures to get the Christian and Pagan festivals amalgamated, and, by a complicated but skilful adjustment of the calendar, it was found no difficult matter, in general, to get Paganism and Christianity – now far sunk in idolatry . . . to shake hands. (3)

T. Enright, Bishop of St. Alphonsus Church, clearly states:

It was the Catholic Church which made the law obliging us to keep Sunday holy.  The church made this law long after the Bible was written.  Hence said law is not in the Bible.  The Cath. [sic.] Church abolished not only the Sabbath, but all the other Jewish festivals. (4)


In this same letter, Enright offers $1000 “to any one who can prove to me from the Bible alone that I am bound, under grievous sin, to keep Sunday holy.”  There is no denying that the Catholic Church is responsible for the change: 

The Commandments, or Decalogue . . . Written by the finger of God on two tables of stone, this Divine code was received from the Almighty by Moses amid the thunders of Mount Sinai . . . Christ resumed these Commandments in the double precept of charity – love of God and of neighbor; He proclaimed them as binding under the New Law in Matt., xix and in the Sermon on the Mount (Matt., v).  He also amplified or interpreted them, . . . The Church, on the other hand, after changing the day of rest from the Jewish Sabbath, or seventh day of the week, to the first, made the Third Commandment refer to Sunday as the day to be kept holy as the Lord’s Day.  The Council of Trent (Sess. VI, can. Xix) condemns those who deny that the Ten Commandments are binding on Christians. (5)

It is not really fair to accuse Roman Catholics of dishonesty when all along they have said that their church changed the day of worship to Sunday.  Following is a sampling of the numerous statements made by Catholics honestly stating that they are responsible for the calendar change that transferred worship to dies Solis:

Because this change occurred so long ago, people today have forgotten the facts of history.  It is impossible to find the Biblical Sabbath via a pagan calendar; therefore, Saturday cannot be the true Sabbath.  Not knowing this, Saturday sabbatarians have assumed that Saturday is the Sabbath from which worship was removed.  It is true that there are plenty of quotes from Catholic writers that refer to Saturday as “Sabbath”:

The facts of history having been forgotten by most people, many Catholic writers have used planetary week terminology (i.e., “Saturday”), which could be considered deceptive.  It is also likely that many of the Catholic writers themselves were unaware of the full history behind the modern week.   Catholic scholars have always known the truth, though.  As conservative Catholic scholar and apologist Patrick Madrid stated:

[The] calendar that we follow, including Seventh-day Adventists, is not only a calendar that was devised by the Catholic Church, but also it is a calendar that’s based upon the solar year, not the lunar year.  And the Jewish calendar that was observed in the time of Christ . . . follows a lunar calendar, which is several days short of the solar year.  So the great irony is that even the Seventh-day Adventists themselves are not worshipping on exactly the same Sabbath day as the Jews of the time of Christ. (6)

Over the centuries, as the facts of history have been forgotten, Saturday has been assumed to be the Biblical seventh-day Sabbath.  However, when the Julian calendar was being enforced upon Christians for ecclesiastical use, no one at the time confused dies Saturni with Sabbato.  All knew that they were two different days bytwo distinct calendar systems.  An excellent example of “Saturday” being knowingly or unknowingly substituted for “Sabbath” is found in the cannons of the Council of Laodicea.

After the edict of Nicæa, apostolic Christians continued to worship by the luni-solar calendar.  The Council of Laodicea was convened approximately 40 years later to enforce the acceptance of “the Lord’s Day” in place of the lunar Sabbath.

In order, therefore, to the accomplishment of her original purpose, it now became necessary for the church to secure legislation extinguishing all exemption, and prohibiting the observance of the Sabbath so as to quench that powerful protest [against worship on Sunday].  And now . . . the “truly divine command” of Constantine and the council of Nicaea that “nothing” should be held “in common with the Jews,” was made the basis and the authority for legislation, utterly to crush out the observance of the Sabbath of the Lord, and to establish the observance of Sunday only in its stead. (7)

Canon 29 of the Council of Laodicea demanded:

Christians shall not Judaize and be idle on Saturday, but shall work on that day; but the Lord’s day they shall especially honor, and, as being Christians, shall, if possible, do no work on that day.  If however, they are found Judaizing, they shall be shut out from Christ.

Roman Catholic bishop, Karl Josef von Hefele (1809-1893), states that the word “Saturday” is supplied in modern translations.  Von Hefele is a very credible authority on the original word choice used at the Council of Laodicea.  A German scholar, theologian and professor of Church history, he was educated at TĪ‹bingen University.  One of his greatest works was History of the Councils of the Church from the Original Documents.  As a bishop and theologian, he certainly had access to original documents in the Vatican archives!

According to von Hefele, the original word used in both the Greek and the Latin was actually “Sabbath.”  The word “anathema” (accursed) was used in place of “shut out.”  The Latin version clearly does not contain any reference to dies Saturni (Saturday) but instead usesSabbato, or “Sabbath”:

Quod non oportet Christianos Judaizere et otiare in Sabbato, sed operari in eodem die.  Preferentes autem in veneratione Dominicum diem si vacre voluerint, ut Christiani hoc faciat; quod si reperti fuerint Judaizere Anathema sint a Christo.

It bears repeating: Christians at the time of the calendar change were not confused over Saturday being the Sabbath.  Everyone knew that dies Saturni had recently been moved from the first day of the pagan week to the last day of the pagan week, while Sabbato was the seventh day of the Jewish luni-solar calendar with which no one in power wished to be associated.  Again, these were two different days on two distinct calendar systems.

Eusebius of Caesarea, a church historian contemporary with Constantine and his frequent flatterer, is often quoted regarding the Sunday legislation of the time.  It is generally believed that he was the priest that finally baptized Constantine shortly before his death.  At the opening ceremonies of the Council of Nicaea, Eusebius sat to the right of Constantine and gave the opening address.(8)  Eusebius was very clear that the exaltation of dies Solis was over the Jewish Sabbato and not over the pagan dies Saturni.

All things whatsoever it was duty to do on the Sabbath, these we have transferred to the Lord’s day, as being more appropriate, and chief, and first, and more honorable than the Jewish Sabbath. (9)

It was at this time that Sylvester I, Bishop of Rome during the Council of Nicaea, attempted to rename the days of the pagan week by the Biblical week-day names.  “This was the era of Constantine the Great, when the public position of the Church so greatly improved, a change which must certainly have been very noticeable at Rome.” (10)

Catholics, knowing full well that there is no Biblical reason to worship on Sunday, have seen how inconsistent Protestants are.

A Catholic who believes that Christ was resurrected on Sunday is far more consistent than a Sunday-keeping Protestant who claims to base all of his belief on the Bible and the Bible only.  Catholics place tradition and the decrees of their popes ahead of the Bible, so there is no inconsistency for them in believing that Sunday is the day of the resurrection.  For them, truth is whatever tradition and their pope decree it to be.


However, for a Protestant to denounce the Catholics for following tradition rather than the Bible, and yet still worship on Sunday, is inconsistent in the extreme.  Furthermore, for Jews and Saturday sabbatarians to insist that The Precise, Correct Day does matter to Yahuwah, and then keep the seventh-day by the pagan, planetary calendar is even more inconsistent!  If it is important to worship on the true Sabbath day, then the original calendar, established by Yahuwah at creation, needs to be used to calculate when that Sabbath comes. 


When the historical facts of the Julian calendar are understood, it is clearly established that Sunday is not the only worship day founded upon pagan calendation.  Saturday, dies Saturni, the original first day of the planetary week is a counterfeit of the true seventh-day Sabbath day of the Bible.


An ancient proverb claimed: “He who controls the calendar, controls the world.”  Who controls you?  The day on which you worship, calculated by which calendar you use, reveals which Deity/deity you are worshipping.
