Shalom Chaverim (Friends),
Of course, there are a lot of difference perspectives, and among Jewish people there are a lot of different perspectives.
As a Jewish believer in Yeshua, I am going to share with you mine, my veiw as for how I see things concerning the Sabbath.
The fourth mitzvah (commandment) of the Ten Commandments concerns the rememberance of the "Shabbat" (Sabbath).
"Shabbat" literally means "rest ... to desist from work."
Unfortunately, through the years, I believe that the "Shabbat" has been misunderstood by both Jews and Christians.
I do not believe that the "Shabbat" was ever intended to be a "intorable burden" laced with hundreds of additional man-made expectations.
I find that God's guidelines for "Shabbat" in the Torah are really quite simple: rest, don't work, and hold a holy convocation to the Lord.
Moreover, no where in Scripture can it be found that God replaced "Shabbat" with Sunday.
So who changed it?
Church history reveals that for "Shabbat" to be replaced by Sunday, was ordained by a Church council only a few centuries after Yeshua.
Moreover, the mitzvah to rest on the "seventh day" did not, in fact, originate in the Ten Commandments, but was sanctified by God at the end of creation! (see Genesis 2:1-3)
The purpose of this special day is to rest, be with family, gather at God's house for worship, and get refocused and refreshed for the coming week.
"Shabbat" is to be a time of rest for our souls as well as our bodies.
The TaNaKH (Hebrew Scriptures) says,
"Remember the day, Shabbat, to set it apart for God."
(see Exodus 20:8)
The B'rit Hadashah (New Covenant Scriptures) says,
"So there remains a Shabbat-keeping for God's people."
(see Hebrews 4:9)
For my part, at least, I chose to take seriously the commandment concerning "Shabbat" and to dedicate this day to the Lord, and to that I add "Lord, help me to live every day resting in you."
Shabbat Shalom.
Yehuda
