I am having an intense struggle in my heart and mind over this issue of the Sabbath. This is a major influence on me and will weigh heavily upon my decision of which Church I will join. I would really appreciate any insight you can give.
May the Lord bless you and keep you. May the Lord make his face to shine upon you, and be gracious to you. May the Lord lift up his countenance upon you, and give you peace.
This is an interesting question and you have made a very good case for Saturday observance. Thank you for that.
As I understand it, the practice of the very earliest followers of the Way, ie those in Jerusalem under James after the Lord's resurrection and ascension, was to attend synagogue on Saturday; the Sabbath. Followers of the Way in this very early church regarded themselves as Jewish, and followed Torah. They preached in synagogues, and in the temple, as the Lord himself did.
Then on Sunday, called the Lord's Day because it commemorated the Resurrection, they met in one another's homes for the Eucharist; thanksgiving for their blessings, and in accordance with the Lord's instructions. There were no Christian churches; their 'church' was still the synagogue. Meetings in homes were for the Eucharist.
All of this changed after the fall of Jerusalem in about 70AD. Tensions between followers of the Way and the Jews had gradually became more and more apparent, until Christians (as they began to be called) were no longer welcome in the synagogue. Believers gradually learned to identify themselves in contradistinction to Judaism, as hostility between the two groups grew. At this point synagogue attendance for Christians was no longer possible, and it would be more and more difficult for any Christian to regard him or herself as a fully Torah observant Jew AND a Christian. There were too many differences by that point for such an identity to be easily held, and this remains true today. Although there are Messianic Christians, they do not have an easy life; Jews don't regard them as Jewish and Christians too often treat them with a lack of charity and (falsely) accuse them of legalism.
So, to the OP. Given that many of us have the unheard of luxury of 2 day weekends there may well be a case for saying, Sunday is the Lord's Day; the day when we commemorate his resurrection by partaking of the Eucharist. Meanwhile, Saturday can remain the Sabbath of the Lord, as given to Moses and not cancelled by Christ. This might be countered, however, by saying that we are to work for six days and rest on one; we are not authorised to have two Sabbaths and therefore must choose one or the other.
So it becomes a choice of three options:
1 Have 2 Sabbaths; one of rest, one of resurrection.
2 Follow Jewish tradition and have Saturday Sabbath, in which case we might have a problem accessing the Eucharist.
3 Follow predominant Christian tradition and have Sunday Sabbath, Sunday Eucharist and worship.
Personally I do not really mind which of these anyone else chooses, as long as their choice is made in all conscience; I do not think any of them are forbidden to Christians because of the example of the very earliest church in Jerusalem, contrasting with later practice as outlined in Acts. Both are Biblical, in other words.
What I think is less acceptable is the pages and pages of argument on this thread, attempting to convince the Others that they are Wrong. They are not wrong; they are following their own conscience on this matter.
Christians are not forbidden from honouring the Sabbath as Jewish people do. There is a very good case to be made for the blessings that this might bring, and the OP has made that case very well imo.
On the other hand, Christians who treat Sunday as their Sabbath are also not under condemnation. This has been the practice of the church for such a very long time that Sunday worship effectively defines our faith; every Sunday is a Feast Day of the Resurrection; a day to celebrate and praise God for his many blessings to us. As long as we are working 6 days and resting 1, it can make little difference to God if, as the Lord tells us, the Sabbath is made for us, not we for the Sabbath.
Whichever anyone chooses, I hope we can remember to speak with respect to the others, and allow them freedom of conscience on this matter.
