Well while I certainly think the OT has many many merits, and should not be discarded, we know much of the "law" was "replaced" with "grace". Leviticus, and I think numbers possibly are some books that provide insight into the early sabbath. However we both know what the Sabbath had become by the time of Jesus. We know the Sabbath basically means to "rest" and we know we use that rest to worship and give glory to God.
Jesus said "The Sabbath was made for man, not man for the sabbath."
so is there really any "specific" way to observe the Sabbath? Other than following the basic principals we observe as Christians and applying them to a gathering? It seems like when Jesus said "The Sabbath was made for man, not man for the Sabbath." he gave us a lot of leeway on how to observe it, because of how societies, and cultures vary. It makes sense because there has to be multiple ways to observe as needed by the situation. When Christians were persecuted we could hardly afford to gather en-mass in the open like we do now.
