From the Catholic catechism;
Q: What day is the Sabbath?
A: Saturday is the Sabbath
Q: Why do we worship on Sunday?
A: Because the Holy Catholic Church changed the day from Saturday to Sunday.
And the mainline protestant churches just followed along. See Daniel 7:25 for eschatological implications of this change, and before anyone tries to "justify" the change through Scripture (please hold the flames), see Revelation 12:17 & 14:12, which state clearly that "keeping the commandments of God" is the thing that the end times are about.
How many FReepers will shout for blood when keeping Sunday is instituted as per the author's suggestion, and some refuse to do it, despite our being a "nation of laws" hmmmm?
Fine, then let's take the whole weekend off. 8-)
Sunday is the "L-rd's Day" (See e.g.:Catholic Home Study Service - Sunday Is The Lord's Day .)

Not only did they change the day....they also changed the way the days were reckoned. God said in Genesis 1:5, "And there was evening, and there was morning-the first day.
The Sabbath begins on Friday at "Even"...sunset, and continues through Saturday at sunset. Modern tradition now stipulates that the new day begins at "Mid-night"???
Isn't it amazing....God's way has 12 hours of darkness and 12 hours of light. So natural. Leave it to mankind to confuse such a simple concept!
The Roman Catholic church, despite its pretentious claim, is not the authority behind the change of the Sabbath from the 7th day to the 1st day (or Lord's Day). Jesus, as Lord of the Sabbath (Mk 2:28), indicated the change himself by rising from the dead and showing himself to his disciples on the first day. His next appearance was on the first day of the following week. Thereafter the apostles, and the church in general, gathered on the first day of the week for worship and celebration of the Lord's Supper (Ac 20:7; 1 Cor 16:2). This day was known to the apostolic church as "the Lord's Day" (Rev 1:10). It has always been so observed by the church, including the Protestants at the Reformation.
At the same time, the obligations of the 4th Commandment are perpetual, since it is part of the moral law (as opposed to the ceremonial law exemplified in the temple worship). The observance of the Sabbath was a creation ordinance patterned after God's own rest at creation, and was not an original Mosaic institution. The reasons for the Old Testament 7th day Sabbath (rest and worship) are precisely the same as the reasons for the Lord's Day. It is therefore evident that Christ, consistent with his Lordship over it, changed the Sabbath from the 7th day to the 1st day as a memorial of his resurrection, and that the obligations of the Old Testament Sabbath now pertain to the Lord's Day.
Three cheers for Hobby Lobby and Chic-filet, courageous businesses in a time of moral declension in society, and doctrinal anaemia in the church. May God bless them.
