Catholic Encyclopedia: Sunday    

Sunday (Day of the Sun), as the name of the first day of the week, is 
derived from   Egyptian astrology.  The seven planets, known to us as 
Saturn, Jupiter, Mars, the Sun,   Venus, Mercury, and the Moon, each had 
an hour of the day assigned to them, and the   planet which was regent 
during the first hour of any day of the week gave its name to   that day 
(see CALENDAR).  During the first and second century the week of seven   
days was introduced into Rome from Egypt, and the Roman names of the 
planets were   given to each successive day.  The Teutonic nations seem to 
have adopted the week as a   division of time from the Romans, but they 
changed the Roman names into those of   corresponding Teutonic deities.  
Hence the <dies Solis> became Sunday (German,   <Sonntag>).  Sunday 
was the first day of the week according to the Jewish method of   
reckoning, but for Christians it began to take the place of the Jewish 
Sabbath in   Apostolic times as the day set apart for the public and solemn 
worship of God.  The   practice of meeting together on the first day of the 
week for the celebration of the   Eucharistic Sacrifice is indicated in Acts, 
xx 7; I Cor., xvi, 2; in Apoc., i, 10, it is called   the Lord's day.  In the 
Didache (xiv) the injunction is given:  "On the Lord's Day come   together 
and break bread.  And give thanks (offer the Eucharist), after confessing 
your   sins that your sacrifice may be pure".  St. Ignatius (Ep. ad Magnes. 
ix) speaks of   Christians as "no longer observing the Sabbath, but living in 
the observance of the   Lord's Day, on which also Our Life rose again".  In 
the Epistle of Barnabas (xv) we   read:  "Wherefore, also, we keep the 
eight day (i. e. the first of the week) with   joyfulness, the day also on 
which Jesus rose again from the dead".

       St. Justin is the   first Christian writer to call the day Sunday (I Apol., 
lxvii) in the celebrated passage in   which he describes the worship 
offered by the early Christians on that day to God.  The   fact that they 
ment together and offered public worship on Sunday necessitated a   
certain rest from work on that day.  However, Tertullian (202) is the first 
writer who   expressly mentions the Sunday rest:  "We, however (just as 
tradition has taught us), on   the day of the Lord's Resurrection ourght to 
guard not only against kneeling, but every   posture and office of 
solicitude, deferring even our businesses lest we give any place to   the 
devil" ("De orat.", xxiii; cf. "Ad nation.", I, xiii; "Apolog.", xvi).

       These and similar   indications show that during the first three 
centuries practice and tradition had   consecrated the Sunday to the public 
worship of God by the hearing of the Mass and   the resting from work.  
With the opening of the fourth century positive legislation, both   
ecclesiastical and civil, began to make these duties more definite.  The 
Council of Elvira   (300) decreed:  "If anyone in the city neglects to come to 
church for three Sundays, let   him be excommunicated for a short time so 
that he may be corrected" (xxi).  In the   Apostolic Constitutions, which 
belong to the end of the fourth century, both the hearing   of the Mass and 
the rest from work are prescribed, and the precept is attributed to the   
Apostles.  The express teaching of Christ and St. Paul prevented the early 
Christians   from falling into the excesses of Jewish Sabbatarianism in the 
observance of the Sunday,   and yet we find St. XXXXXX of Arles in the 
sixth century teaching that the holy Doctors   of the Church had decreed 
that the whole glory of the Jewish Sabbath had been   transferred to the 
Sunday, and that Christians must keep the Sunday holy in the same   way 
as the Jews had been commanded to keep holy the Sabbath Day.  He 
especially   insisted on the people hearing the whole of the Mass and not 
leaving the church after   the Epistle and the Gospel had been read.  He 
taught them that they should come to   Vespers and spend the rest of the 
day in pious reading and prayer.  As with the Jewish   Sabbath, the 
observance of the Christian Sunday began with sundown on Saturday 
and   lasted till the same time on Sunday.  Until quite recent times some 
theologians taught   that there was an obligation under pain of venial sin 
of assisting at vespers as well as of   hearing Mass, but the opinion rests 
on no certain foundation and is now commonly   abandoned.  The 
common opinion maintains that, while it is highly becoming to be   
present at Vespers on Sunday, there is no strict obligation to be present.  
The method of   reckoning the Sunday from sunset to sunset continued in 
some places down to the   seventeenth century, but in general since the 
Middle Ages the reckoning from midnight   to midnight has been 
followed.  When the parochial system was introduced, the laity   were 
taught that they must hear Mass and the preaching of the Word of God on   
Sundays in their parish church.  However, toward the end of the 
thirteenth century, the   friars began to teach that the precept of hearing 
Mass might be fulfilled by hearing it in   their churches, and after long 
and severe struggles this was expressly allowed by the   Holy See.  
Nowadays, the precept may be fulfilled by hearing Mass in any place 
except   a strictly private oratory, and provided Mass is not celebrated on 
a portable alter by a   privilege which is merely personal.

       The obligation of rest from work on Sunday   remained somewhat 
indefinite for several centuries.  A Council of Laodicea, held   toward the 
end of the fourth century, was content to prescribe that on the Lord's Day   
the faithful were to abstain from work as far as possible.  At the beginning 
of the sixth   century St. Caesarius, as we have seen, and others showed an 
inclination to apply the   law of the Jewish Sabbath to the observance of 
the Christian Sunday.  The Council held   at Orleans in 538 reprobated 
this tendency as Jewish and non-Christian.  From the eight   century the 
law began to be formulated as it exists at eh present day, and the local   
councils forbade servile work, public buying and selling, pleading in the 
law courts,   and the public and solemn taking of oaths.  There is a large 
body of civil legislation on   the Sunday rest side by side with the 
ecclesiastical.  It begins with an Edict of   Constantine, the first Christian 
emperor, who forbade judges to sit and townspeople to   work on Sunday.  
He made an exception in favour of agriculture.  The breaking of the   law 
of Sunday rest was punished by the Anglo-Saxon legislation in England 
like other   crimes and misdemeanours.  After the Reformation, under 
Puritan influence, many   laws were passed in England whose effect is 
still visible in the stringency of the English   Sabbath.  Still more is this the 
case in Scotland.  There is no federal legislation in the   United States on 
the observance of the Sunday, but nearly all the states of the Union   have 
statues tending to repress unnecessary labour and to restrain the liquor 
traffic.  In   other respects the legislation of the different states on this 
matter exhibits considerable   variety.  On the continent of Europe in 
recent years there have been several laws passed   in direction of 
enforcing the observance of Sunday rest for the benefit of workmen.
