Absolutely agreed. However, in Hebrews 7-8, we read this (emphasis mine):
"For on the one hand, a former commandment is set aside because of its weakness and uselessness (for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God. And it was not without an oath. For those who formerly became priests were made such without an oath, but this One was made a priest with an oath by the One Who said to Him: 'The Lord has sworn and will not change His mind, "You are a priest forever."’ This makes Jesus the guarantor of a better covenant. The former priests were many in number, because they were prevented by death from continuing in office, but He holds His priesthood permanently, because He continues forever. Consequently, He is able to save to the uttermost those who draw near to God through Him, since He always lives to make intercession for them. Now the point in what we are saying is this: we have such a high priest, One Who is seated at the right hand of the throne of the Majesty in heaven, a minister in the holy places, in the true tent that the Lord set up, not man. For every high priest is appointed to offer gifts and sacrifices; thus it is necessary for this priest also to have something to offer. Now if He were on earth, He would not be a priest at all, since there are priests who offer gifts according to the law. They serve a copy and shadow of the heavenly things. For when Moses was about to erect the tent, he was instructed by God, saying, 'See that you make everything according to the pattern that was shown you on the mountain.' But as it is, Christ has obtained a ministry that is as much more excellent than the old as the covenant He mediates is better, since it is enacted on better promises. For if that first covenant had been faultless, there would have been no occasion to look for a second."
[Hebrews 7:18-8:7]
I'll just say that it is not of utmost importance that we get the day of the week exactly correct, but just that we, as God said,
"(r)emember the Sabbath day, to keep it holy" (Exodus 20:8), and that we
"not (neglect) to meet together, as is the habit of some, but (encourage) one another, and all the more as (we) see the Day drawing near" (Hebrews 10:25).
Grace and peace to you, Phoneman.
