Concerning the Sabbath, the Catholic Church never changed the time of the Sabbath.
The Bible says they changed it….and they admit they changed it, as the following explains…..
To complete the sacrilegious work, Rome presumed to expunge from the law of God the second commandment, forbidding image worship, and to divide the tenth commandment, in order to preserve the number.
The spirit of concession to paganism opened the way for a still further disregard of Heaven’s authority. Satan, working through unconsecrated leaders of the church, tampered with the fourth commandment also, and essayed to set aside the ancient Sabbath, the day which God had blessed and sanctified (Genesis 2:2, 3), and in its stead to exalt the festival observed by the heathen as “the venerable day of the sun.” This change was not at first attempted openly. In the first centuries the true Sabbath had been kept by all Christians….as Jesus said: “IF you love me, keep my commandments”, (John 14:15).
They were jealous for the honor of God, and, believing that His law is immutable, they zealously guarded the sacredness of its precepts. But with great subtlety Satan worked through his agents to bring about his object. That the attention of the people might be called to the Sunday, it was made a festival in honor of the resurrection of Christ. Religious services were held upon it; yet it was regarded as a day of recreation, the Sabbath being still sacredly observed.
To prepare the way for the work which he designed to accomplish, Satan had led the Jews, before the advent of Christ, to load down the Sabbath with the most rigorous exactions, making its observance a burden.
Now, taking advantage of the false light in which he had thus caused it to be regarded, he cast contempt upon it as a Jewish institution (Which the Bible never claims). While Christians generally continued to observe the Sunday as a joyous festival, he led them, in order to show their hatred of Judaism, to make the Sabbath a fast, a day of sadness and gloom.
In the early part of the fourth century the emperor Constantine issued a decree making Sunday a public festival throughout the Roman Empire.
The day of the sun was reverenced by his pagan subjects and was honored by Christians; it was the emperor’s policy to unite the conflicting interests of heathenism and Christianity. He was urged to do this by the bishops of the church, who, inspired by ambition and thirst for power, perceived that if the same day was observed by both Christians and heathen, it would promote the nominal acceptance of Christianity by pagans and thus advance the power and glory of the church. But while many God-fearing Christians were gradually led to regard Sunday as possessing a degree of sacredness, they still held the true Sabbath as the holy of the Lord and observed it in obedience to the fourth commandment.
The archdeceiver had not completed his work. He was resolved to gather the Christian world under his banner and to exercise his power through his vicegerent, the proud pontiff who claimed to be the representative of Christ. Through half-converted pagans, ambitious prelates, and world-loving churchmen he accomplished his purpose. Vast councils were held from time to time, in which the dignitaries of the church were convened from all the world. In nearly every council the Sabbath which God had instituted was pressed down a little lower, while the Sunday was correspondingly exalted. Thus the pagan festival came finally to be honored as a divine institution, while the Bible Sabbath was pronounced a relic of Judaism, and its observers were declared to be accursed.
The great apostate had succeeded in exalting himself “above all that is called God, or that is worshiped.” 2 Thessalonians 2:4.
He had dared to change (Daniel 7:25) the only precept of the divine law that unmistakably points all mankind to the true and living God. In the fourth commandment, God is
revealed as the Creator of the heavens and the earth, and is thereby distinguished from all false gods. It was as a memorial of the work of creation that the seventh day was sanctified as a rest day for man. It was designed to keep the living God ever before the minds of men as the source of being and the object of reverence and worship.
Satan strives to turn men from their allegiance to God, and from rendering obedience to His law; therefore he directs his efforts especially against that commandment which points to God as the Creator.
Protestants now urge that the resurrection of Christ on Sunday made it the Christian Sabbath. But Scripture evidence is lacking. No such honor was given to the day by Christ or His apostles. The observance of Sunday as a Christian institution had its origin in that “mystery of lawlessness” (2 Thessalonians 2:7, R.V.) which, even in Paul’s day, had begun its work. Where and when did the Lord adopt this child of the papacy? What valid reason can be given for a change which the Scriptures do not sanction?
“Protestants accept Sunday rather than Saturday as the day for public worship ‘after’ the Catholic Church made the change …..BUT the Protestant mind does not seem to realize that….in observing the Sunday, they are accepting the authority of the spokesman for the church, the Pope”, (‘Our Sunday Visitor’, February 5, 1950).
Romans 6:16 “Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness ?”
“Sunday is a Catholic insitution,and its claims to observance can be defended only on Catholic principles….Fromthe beginning of scripture to the end (Genesis-Revelation) there is not one single passage that warrants the transfer of public worship from the 7th day of the week, to the 1st day of the week”, (‘Catholic Press’, Sydney, Autralia, August, 1900).
“IF Protestants would follow the Bible, they shouldworship God on the Sabbath day. In keeping the Sunday they are following a Law of the Catholic Church” (Albert Smith, Chancellor of the Archdiocese of Baltimore, replying for the Cardinal, in a letter dated February 10, 1920).
“The Church changed the observance of the Sabbath to Sunday by right of the divine, unfallable authority given her by her founder, Jesus Christ.
The Protestant claiming the Bible to be their only guide to faith, has no warrant for observing Sunday.
In this matter, the Seventh-Day Adventist is the only consistent Protestant”, (“The Catholic Universe Bulletin’, August 14, 1942).
“It was the Catholic church which by the authority of Jesus Christ, has transferred this rest (from the Bible Sabbath) to Sunday….Thus the observance of Sunday by the Protesant is in homage they pay, in spite of themselves, to the authority of the Catholic Church”, (Monsignor
Louis Segur, ‘Plain Talk about the Protestant of Today’, Page 213).
