I also agree that to change the Seventh Day Sabbath to Sunday is something the scriptures absolutely give no warrant to do.
Really? Since when? Have I finally found something over which we actually disagree? Someone bring out the flags right now please. Sorry veks, but you're on the wrong side of this argument. Both the NT and early church fathers most emphatically attest to the change to Sunday as the traditional day of Christian worship.
Maybe your lack of Greek background & knowledge has made you vulnerable to SDA, JW, WWCoG and Jewish 'logic'. I could, for example, cite a lot more evidence than Rev. 1:10, but that reference alone is enough to sink all sabbatarian arguments without trace. For they all come to grief on the hard fact that Κυριακή ημέρα is tautologically and eponymously both the Lord's Day and the first (or 8th) day of the week, and has been the Gk for Sunday since its earliest recorded usage in the most ancient extant authorities, including the NT itself. Ask any Gk what day is Κυριακή ημέρα (pronounced kiriaki imera), and without fail, they will tell you 'Sunday' whilst simultaneously wondering 'what's this dingbat's problem?'
Please don't make me pull out my Arndt/Gingrich/Bauer to prove my point, but I will if I hafta, and I can promise you, you won't survive the onslaught. I really would hate to bash you about the head with the biggest tome in my library.
But if you are now feeling a little bruised, don't forget I still love you, despite this minor spat over nothing very much.
