What the messianics sometimes fail to understand is that old covenant gave way to new. The rabbis went in one direction while Jesus and His apostles when in another. The old covenant Sabbath was temporary, and looked on as an accommodation within the new Christian community until the transition from old covenant to new was completed. This happened around AD70 with the destruction of the temple. We see a gradual transition in the NT, esp., in Acts as more and more gentiles are added to the faith.
The only “Christians” who continued to insist on a seventh-day religious sabbath were the heretics like the Ebionites. Today we have a new breed of Ebionite. Trying to follow shadowy, ersatz old covenant forms, some not sure of the trinity, trying to place gentiles under the (expired) law of Moses.

Are we there yet ? Do you mean YHvH's New Covenant as in Jeremiah 31:31-37 ?
