Who changed the Sabbath to Sunday?

Below are statements from the Roman Catholic Church which give the simple answer as to why most Churches now keep Sunday as the Sabbath. Most Christians have no idea that this even happened or how it happened. Revelation 13 tells us that Satan gave his power and authority to the Catholic Church. Why? It was Satan's plan to have this Church change the Sabbath to Sunday. Why did Satan do this? The Sabbath is about who we give our allegiance to. If we obey God and keep His Sabbath day Holy, we give our allegiance to God. If we obey the Commandment of the Catholic Church and keep their day Holy, who do we give our allegiance to then? The Catholic Church answers this question below with two of their quotes. But looking deeper, who gave this Church power so God’s true day of worship could be changed?

Does the Bible support the change to Sunday? “Most Christians assume that Sunday is the biblically approved day of worship. The Catholic Church protests that it transferred Christian worship from the biblical Sabbath (Saturday) to Sunday, and that to try to argue that the change was made in the Bible is both dishonest and a denial of Catholic authority. If Protestantism wants to base its teachings only on the Bible, it should worship on Saturday.” Rome’s Challenge www.immaculateheart.com/maryonline Dec 2003
“For example, nowhere in the Bible do we find that Christ or the Apostles ordered that the Sabbath be changed from Saturday to Sunday. We have the commandment of God given to Moses to keep holy the Sabbath day, that is the 7th day of the week, Saturday. Today most Christians keep Sunday because it has been revealed to us by the [Roman Catholic] church outside the Bible.” Catholic Virginian, October 3, 1947, p. 9, article “To Tell You the Truth.”

Who Made Sunday Holy? “Perhaps the boldest thing, the most revolutionary change the Church ever did, happened in the first century. The holy day, the Sabbath, was changed from Saturday to Sunday. ‘The day of the Lord’ was chosen, not from any direction noted in the Scriptures, but from the (Catholic) Church’s sense of its own power...People who think that the Scriptures should be the sole authority, should logically become 7th Day Adventists, and keep Saturday holy.” St. Catherine Church Sentinel, Algonac, Michigan, May 21, 1995.
“Question - Which is the Sabbath day?“Answer - Saturday is the Sabbath day.“Question - Why do we observe Sunday instead of Saturday?“Answer - We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A.D. 364), transferred the solemnity from Saturday to Sunday.” Peter Geiermann, C.S.S.R., The Convert’s Catechism of Catholic Doctrine, p. 50, 3rd edition, 1957.

Whose Day of Worship is Sunday? “They [the Protestants] deem it their duty to keep the Sunday holy. Why? Because the Catholic Church tells them to do so. They have no other reason...The observance of Sunday thus comes to be an ecclesiastical law entirely distinct from the divine law of Sabbath observance...The author of the Sunday law...is the Catholic Church.” Ecclesiastical Review, February 1914.
“It is well to remind the Presbyterians, Baptists, Methodists, and all other Christians, that the Bible does not support them anywhere in their observance of Sunday. Sunday is an institution of the Roman Catholic Church, and those who observe the day observe a commandment of the Catholic Church.” Priest Brady, in an address reported in The News, Elizabeth, New Jersey, March 18, 1903.

Who Do We Reverence by Keeping Sunday Holy? “It was the Catholic church which...has transferred this rest to Sunday in remembrance of the resurrection of our Lord. Therefore the observance of Sunday by the Protestants is an homage they pay, in spite of themselves, to the authority of the (Catholic) church.” Monsignor Louis Segur, Plain Talk About the Protestantism of Today, p. 213.

Who Made Sunday Holy? “Written by the finger of God on two tables of stone, this Divine code (ten commandments) 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 the neighbour; He proclaimed them as binding under the New Law in Matthew 19 and in the Sermon on the Mount (Matthew 5)...The (Catholic) 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...He (God) claims one day out of the seven as a memorial to Himself, and this must be kept holy...”The Catholic Encyclopaedia, vol. 4, “The Ten Commandments”, 1908 edition by Robert Appleton Company; and 1999 Online edition by Kevin Knight, Imprimatur, John M. Farley, Archbishop of New York.

Note 1: Paul and Peter both predicted false teachers would come after their death:
(Acts 20:29-30) "For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them."
(1 Timothy 4:1) "Now the Spirit speaks expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of demons;"
(2 Peter 2:1-2) "But there were false prophets also among the people, even as there shall be false teachers among you, who privately shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of."

Doctrines of Devils and False teachers: They teach that Jesus rose on Sunday, and that Sunday is the day of worship and rest.
Privily shall bring in damnable heresies: In the privacy of the council of Laodicea, they substituted Sunday for the Sabbath.
Denying the Lord: It was Jesus who said, "keep the commandments." (Matthew 19:17), "but in works they deny him," (Titus 1:16), by not keeping them.
Many shall follow their pernicious ways: Almost all of Christianity keeps Sunday as a day of worship, instead of the Sabbath.
The way of truth shall be evil spoken of: Almost all of Christianity speaks against keeping the Sabbath commandment, which is the truth (Psalm 119:151).The scripture has this to say on the matter:

(Romans 6:16) "Do you not know, that to whom you yield yourselves servants to obey, his servants you are to whom you obey;"So who are we obeying when we keep Sunday as a day of worship instead of Saturday?

(1) We are obeying men, because men changed the Sabbath commandment for Sunday, and we are told not to do this:

(Acts 5:29) "Then Peter and the other apostles answered and said, We ought to obey God rather than men."(1 Corinthians 7:23) "You are bought with a price; do not you be the servants of men."

God commanded the Sabbath, and men commanded Sunday

(2) We are obeying the spirit of Antichrist, because it is the Antichrist, who will "think to change times and laws:" (Daniel 7:25). This spirit was already in the world in the time of the apostles, for John wrote, "this is that spirit of antichrist, whereof you have heard that it should come; and even now already is it in the world." (1 John 4:3). The spirit of antichrist is really the spirit of the Devil, because he is the one who gives the antichrist his authority:

(Revelation 13:2) "the dragon gave him his power, and his seat, and great authority."

Therefore, when we obey the commandments of men (keeping Sunday), which is inspired by the spirit of antichrist, we are really bowing to Satan because we keep his law instead of God's.

Note 2: Jesus had things to say about honouring man's tradition:

(Matthew 15:1-9) "Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying,
2 Why do your disciples transgress the tradition of the elders? for they do not wash their hands when they eat bread
3 But he answered and said to them, Why do you also transgress the commandment of God by your tradition?
4 For God commanded, saying, Honour your father and mother: and, He who curses father or mother, let him die the death.
5 But you say, Whoever shall say to his father or his mother, It is a gift, by whatever you might be profited by me;
6 And does not honour his father or his mother, he shall be free. Thus you have made the commandment of God of no effect by your tradition.
7 You hypocrites, well did Isaiah prophesy of you, saying,
8 This people draws near to me with their mouth, and honours me with their lips; but their heart is far from me.
9 But in vain they do worship me, teaching for doctrines the commandments of men."

Jesus severely rebuked the Pharisees, and called them hypocrites (v7), for pretending to love God, while at the same time breaking one of the Ten Commandments by their tradition. Where does this leave you dear reader? Do you say that you love God, while at the same time break the Sabbath commandment? Are you honouring the tradition of men (keeping Sunday), or honouring the commandment of God (keeping the Sabbath)?
