Sabbath day was never a day of worship forrest, but only ever a day of rest from labor. Worship is the seven days a week part that Protestants have dropped, we only "worship" one day a week now right lol, so we have a perfect score, every principle is warped now.
The Romans changed the name to Saturn-day btw, from Sabado or Sabata or Shabbat. i could even eventually dig up the edict, but it was mostly Roman custom first, i mean we even observe a Roman calendar lol. Every time you say "Saturday" you are bowing to Rome and Saturn, whether in ignorance or not. Iow our name for Sabbathday is even corrupted now; if you want the real name, ask a Latino.
The name we use was enacted by law under punishment of death, of course
maybe it was in the Saturnalia, i'll snoop around
Pax!
