Why Most churches Worship on Sunday
The seven-day week originates with in ancient Babylon prior to 600 BC, when time was marked with the lunar cycle, which experienced different seven-day cycles. Also note that the Jewish calendar is one of the oldest if not the oldest calendar in history. A millennium later, Emperor Constantine(The 88th pope) converted Rome to Christianity and standardized the seven-day week across the Empire. Rome may initially have acquired the seven-day week from the mystical beliefs of Babylonian astrologers. But it was the biblical story of creation, God making the Heavens and Earth and resting on the seventh day that will have led the first Christian emperor of Rome to make sure it endured to this day. Here are various Catholic sources claiming the change was the doing of the Roman Catholic Church:
The infiltration of Christianity by the Catholic Church (source)
The 88th Pope, Constantine but in most history books he is known as an Roman emperor, this was purposefully done by the way.
Our Sunday Visitor (February 5, 1950):
"Practically everything Protestants regard as essential or important they have received from the Catholic Church... The Protestant mind does not seem to realize that in accepting the Bible and observing the Sunday, in keeping Christmas and Easter, they are accepting the authority of the spokesman for the church, the Pope."
Louis Gaston Segur, Plain Talk about the Protestantism of To-Day (London: Thomas Richardson and Son, 1874): 213:ur Sunday Visitor (February 5, 1950):
"Thus the observance of Sunday by the Protestants is a homage they pay, in spite of themselves, to the authority of the (Catholic) Church."
John A. O'Brien, The Faith of Millions: the Credentials of the Catholic Religion Revised Edition (Our Sunday Visitor Publishing, 1974): 400-401:
states "But since Saturday, not Sunday, is specified in the Bible, isn't it curious that non-Catholics, who claim to take their religion directly from the Bible and not from the Church, observe Sunday instead of Saturday? Yes, of course, it is inconsistent; but this change was made about fifteen centuries before Protestantism was born, and by that time the custom was universally observed. They have continued the custom even though it rests upon the authority of the Catholic Church and not upon and explicit text in the Bible. That observance remains as a reminder of the Mother Church from which the non-Catholic sects broke away—like a boy running away from home but still carrying in his pocket a picture of his mother or a lock of her hair."
In the late John O' Brien's book "Faith of Millions" he writes:
"When the priest pronounces the tremendous words of consecration, he reaches up into the heavens, brings Christ down from His throne, and places Him upon our altar to be offered up again as the Victim for the sins of man. It is a power greater than that of monarchs and emperors: it is greater than that of saints and angels, greater than that of Seraphim and Cherubim. Indeed it is greater even than the power of the Virgin Mary. While the Blessed Virgin was the human agency by which Christ became incarnate a single time, the priest brings Christ down from heaven, and renders Him present on our altar as the eternal Victim for the sins of man—not once but a thousand times! The priest speaks and lo! Christ, the eternal and omnipotent God, bows His head in humble obedience to the priest’s command."
Stephen Keenan, Catholic—Doctrinal Catechism 3rd Edition: 174:
states "Question: Have you any other way of proving the Church has power to institute festivals of precept?
Answer: Had she not such power, she could not have done that in which all modern religionists agree with her, she could not have substituted the observance of Sunday the 1st day of the week, for the observance of Saturday the 7th day, a change for which there is no Scriptural authority".

Chancellor Albert Smith for Cardinal of Baltimore Archdiocese, letter dated February 10, 120:
states "If Protestants would follow the Bible, they should worship God on the Sabbath day by God is Saturday. In keeping the Sunday, they are following a law of the Catholic Church".
The Convert's Catechism of Catholic Doctrine (1957): 50:
Q. Which is the Sabbath day?
A. Saturday is the Sabbath day.
Q. Why Do we observe Sunday instead of Saturday?
A. We observe Sunday instead of Saturday because the Catholic Church transferred the solemnity from Saturday to Sunday.
Cardinal James Gibbons, The Faith of Our Fathers (Ayers Publishing, 1978): 108:
states "But you may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday, a day which we never sanctify."
Catholic Priest T. Enright, CSSR, Kansas City, MO:
"It was the holy Catholic Church that changed the day of rest from Saturday to Sunday, the 1st day of the week. And it not only compelled all to keep Sunday, but at the Council of Laodicea, AD 364, anathematized those who kept the Sabbath and urged all persons to labor on the 7th day under penalty of anathema."
Pope Leo XIII, Praeclara Gratulationis Publicae (The Reunion of Christendom), June 20, 1894:
"We hold upon this earth the place of God Almighty."
BENEDICT XVI at Saint Peter's Basilica Holy Saturday, 23 April 2011:
states "The Sabbath is the seventh day of the week. After six days in which man in some sense participates in God’s work of creation, the Sabbath is the day of rest. But something quite unprecedented happened in the nascent Church: the place of the Sabbath, the seventh day, was taken by the first day. As the day of the liturgical assembly, it is the day for encounter with God through Jesus Christ who as the Risen Lord encountered his followers on the first day, Sunday, after they had found the tomb empty." Remember, there is no place in the bible claiming Sunday as the sabbath.
