There is nothing “ceremonial” or “shadow”y about the Sabbath. It was a straight-forward commemoration of the Creation of the universe. A pretty awesome event. We are given this one day to worship God and His Goodness and reflect on our duties to Him. You have free will. Take a pass if you wish.
Wrong; under the new cov. required annual religious observances of "days, and months, and times, and years" are not upheld, and no OT specific day of worship is mandated while holydays, or the new moon, or the sabbath days are distinctly stated to be a a shadow of things to come. (Col,. 2:16)
It is simply unreasonable to suppose the 4th commandment would not be reiterated or repeated while the rest are, and the only teaching regarding Christian observance of the 7th day is that which makes it part of the ceremonial laws, and a shadow of the rest that believers are given in Christ, and that the only specific day the NT church met together was the 1st day.
And based on your past statements, it does not appear you think a believer has freedom in the issue if he will be saved.
Time to enter my daily rest now!
