1 Cor 16:2 (ESV)
2 On the first day of every week, each of you is to put something aside and store it up, as he may prosper, so that there will be no collecting when I come
Acts 20:7 (ESV)
7 On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight
It's a pity when a believer deliberately misleads others. How do these verses endorse Sunday worship or abrogate the Sabbath? Have you not read that the apostles broke bread daily? The verse about collecting offerings leaves the question of worship. Keeping the Sabbath is more than collecting offerings.
Acts 2
42 And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.
43 And fear came upon every soul: and many wonders and signs were done by the apostles.
44 And all that believed were together, and had all things common;
45 And sold their possessions and goods, and parted them to all men, as every man had need.
46 And they,
continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,
To compare the Sabbath to the Passover is to be disingenuous. One is the fourth commandment, while the other is part of ceremonial law. Would you say not committing adultery is as biding as keeping the feast of weeks? In any case, Christians celebrate Passover regularly, hence if some ceremonial laws are so well kept, what about the commandments? The Ten Commandments have never been abrogated, and the sanctity of the Sabbath remains. When you get a scriptural abrogation of the Sabbath commandment, the debate can progress. Let me repeat the questions asked by the author of the Catholic Mirror articles.
1st. Which day of the week does the Bible enjoin to be kept holy?
2nd. Had the New Testament modified by precept or practice the original command?
3rd. Have Protestants, since the sixteenth century, obeyed the command of God by keeping "holy" the day enjoined by their infallible guide and teacher, the Bible? And if not, why not?
By the third question, the Catholic Mirror opens up that only up to the 16th Century, Christians kept the Sabbath (some kept both Saturday and Sunday). It was only up to the 16th Century that the Reformation picked up and unveiled her nakedness (tradition over the word of God).
Let me recap some of the arguments that have been brought up in response to Rome's Challenge (here and elsewhere).
1. Sunday is the Lord's Day. This has been thoroughly discredited. All references in the bible about "the day of the Lord" are about the day of judgment. The Catholic Mirror shows it better than I ever could.
2. The Catholic church transferred solemnity from Saturday to Sunday. This is the brutal, honest truth. The church purported to change the law of God.
3. Paul met Christians on the first day of the week to collect offerings. This is no command to overturn the fourth commandment.
4. Jesus rose on Sunday, so we worship on that day. Nowhere do you see Christ asking the church to mark the day, nor does scripture record the apostles keeping Sunday in this manner. The same deception brought about Christmas, a pagan holiday adopted by apostate Christianity. Christ never marked his own birthday.
5. We have lost track of time, so you cannot tell which is the Sabbath. Jews exist for a good reason. They have never lost track of the weekly cycle. In any case, Sunday keepers never bring up this question when they worship Sunday after Sunday like clockwork.
6. The Sabbath is not binding today, it was nailed to the cross. A preposterous claim. Were the commandments to honor father and mother, not commit adultery, not to steal etc also nailed to the cross? Christians have no problem with the Ten commandments, but when you ask them about the fourth commandment, they begin to google in the sand.
7. We do not worship the Sabbath, every day is the same. Another hollow argument, considering that the Sunday worshipers keep Sunday faithfully.
8. Anybody can choose his own day to worship. That would be fine for idol worship or those who worship themselves. Nobody makes such excuses for other commandments. The Sabbath is commanded by God and not man.
